Record Scorcher Across Western Pacific, Blowing Yellow Sand Tracks To Japan’s Northeast

Iloilo City, Philippines, 23 April 2012, (1600Z)–Intense heat induced by prevailing “Ridge of High Pressure,” along the Northwest Pacific has caused record-high temperatures across Southeast Asia. In Manila, Philippines alone, the state weather bureau, Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) has yet again raised the alarm of excessive heat in the metro where Mercury rising rapidly at maximum of 36.8C at 0700Z (0300PM-PHL/MAL), recorded at Science Garden in Quezon City, and a lot higher at 38C in Cabanatuan City. Many Filipinos have been trying to keep cool under the heat of the Sun as this year’s Summer heat was among the most intense since 2010.

 As the heat continues to peak usually this April, a respite from all these has not yet arrived and there had been observations that in the country alone, for the last decade, the number of hotter-than-usual periods have become more evident, which now ushers lesser number of hours of cooling, as a result, the relative humidity in cities across the country have been intensely associated with the prevalence of concrete structures and lesser vegetation as compared to the rural areas where lush trees, open spaces and adequate interval between structures can still be found.

At some point there had been sporadic rains associated with the “Orographic lift,” from which warm air collides with cold air, where such occurrence usually happen along the terrains or near bodies of water, that could produce precipitable water in the clouds, that could propagate rain-bearing thunderstorms, if all things go well into place.

In Thailand capital Bangkok, temperatures soar at 40C, one of the most extreme in the region so far, wherein Tropical moisture have become trapped especially in the metropolis heat where paved roads, wide concrete spaces and towering superstructures tend to trap in the heat and increase the “Real-feel,” of the human body as relative humidity also shoots up and as “H2O molecules,” becomes super-heated, the air becomes rapidly evaporates and condensation do not eventually result to rain-bearing clouds, which only add up to the unbearable heat.

 

Terrible Heat Spawn Thunderstorms

Usually, “Cumulonimbus,” (Cb) clouds form due to rising of warm air and colliding with cooler winds produce rain-bearing clouds, but are commonly referred to as developing thunderstorms, which shoots higher into the upper atmosphere several thousands of kilometers in altitude to begin a process of evaporation and condensation that could potentially bring some severe weather, at some point lead to “Hail” storms and in some occasions, they become so severe, it may produce some “Tornado,” in the process.

Malaysia Peninsula, however got some cloudy periods but less rainfall was being reported. Borneo however, has gotten some precipitation today under the intense tropical heat.

 

Severe Weather Over Hong Kong Territory

In Hong Kong, authorities have been issuing warnings for potentially “Severe,” storms brought about by a lingering “Low” over the territory which has traversed Central China for the last two (2) days. It has already brought huge amounts of rainfall and lightning storms can be seen across the metropolis throughout the night. The said weather system should continue to track Eastwards, reaching Northern Taiwan by tomorrow afternoon, and by Sunday, it should affect the Southern seaboards of the Korean Peninsula and once again, Japanese coast can expect another wave of severe weather, with potential for high winds, thundery rains well into Monday work-week if the system does not stall over the Yellow Sea and Sea of Japan in the process.

At the moment, a choking and blinding “Dust storm,” from the Gobi Deserthas been whipping towards the Yellow Sea from Northern and Eastern Chinese border. The Westerlies prevailing over the region, compounded by dry winds blowing to the East, as the exiting “Low,” that has traversed over Japanese Islands these past few days have been tracking Northeastwards, pulling along with it the “Yellow wind,” dubbed as “Aeolian sand,” which has now reached the Northernmost region of Hokkaido.

The said phenomenon intervenes with visibility in the region, and at times, cancellation of transportation can add up to the anxiety especially during windy conditions.

Tropical Disturbance “97W,” has been battered by the persistent “Ridge of High Pressure,” North of it for the last three-four (3-4 ) days now, and the compounding drier region of air mass has been inflicting detrimental conditions to its “Low-level circulation center,” (LLCC). The Joint Typhoon Warning Center (JTWC) in Hawaii Island, USA has pegged the system has a “Low” chance of development.

Looking Forward Into The Forecast

Meanwhile, the trailing Intertropical Convergence Zone (ITCZ) across the Tropics, has been more evident along the lower Pacific, near the Equator, which has yet to usher more thunderstorm activity Westwards, and has a potential to spawn a Tropical Cyclone in the foreseeable weeks.

This would be all for now, from your Weatherguy, hailing from the Philippines! =)

BREAKING: Deep Low Over Japan Moving Away, Rough Conditions Persist Over Vladivostok; Extreme Tropical Heat In Philippine Archipelago, Malaysian Peninsula Surges On

By: Weatherguy Adonis

Adonis S. Manzan

Deep “Low” Ushers Bad Weather Across Japan, Korean Peninsula & Vladivostok

Iloilo City, Philippines, 23 April 2012, (1600Z)–Earlier on Sunday, 22 April 2012, a massive “Low” forges forward off the Yellow Sea, and into West & Southern Japanese Islands, bringing heavy rains and sporadic thunderstorms which has become severe in Naha, Okinawa and the Ryukus Region, and Muroto, just Southwest of Tokushima. The severe weather has also caused disruptions in transportation as dangerous conditions such as flooding potential and occurrence of “Tornadic” activity was not ruled out by the local authorities.

According to Japan Meteorological Agency (JMA), the deep “Low” Pressure system was causing windy conditions and rough seas, along the East China Sea and the Sea of Japan. The highest winds were recorded near Ryukus Islands, where based on ASCAT wind analysis, I have been observing that top winds have reached to 50 kt (92 km/hr) at most, with stronger gusts as the system continues to drape the Japanese mainland with much convective clouds, and trailing along with it was an active “Front,” anchored along another area of “Low,” just off Hainan Island, in China.

JMA has been issuing several watches on the severe thunderstorm activity affecting the Ryukus Islands, and some parts of Fukui Region, and in Tsuruga, where the agency has been watching a potential for a “Tornado,” of which they have been issuing a “Level 1,” advisory there since 1500-JST (0600Z/0200PM-PHL/MAL).

Heavy precipitation was being observed also especially along Naha, in Okinawa Island, and in Ryukus Islands, wherein rainfall accumulation has reached to 150 mm to 200 mm in just 2 hours of intense rainfall brought about by the system. There were no reports of damage to property or injuries associated with the storm in the region.

The storm has been especially slow in its track Northeastwards, but remains “Quasi-stationary,” at the moment along Vladivostok, the Russian Federation territory.

High Pressure Ridge Pushes “Front,” To Dip South, New “Spring Storm” In Progress

The said “Front,” was being forecast to move through along the Okinawa Region within the next 12 hrs, pushing the “Low,” clear off Japan’s West and Central Prefectures by early Monday afternoon. Having said that, the “Front,” was being pushed ultimately Southwards by a dominant “Ridge of High Pressure,” that has been persistent for the last four (4) days along the East Chinese mainland, causing the spillage into the Northwestern periphery of Luzon and the Taiwanese Islands, in between Batanes Island Group and the Babuyan Channel to the North of the Philippines. This has been the reason for a surge of cooler air mass from the West Philippine Sea, a.k.a. “South China Sea,” which has been oscillating some thunderstorms across the Northernmost towns of Luzon, especially along Cagayan and Isabela Provinces to the East, and the grand Cordilleras Region to the Center of Luzon, flanked by Zambales to the West, and Manila in the farther South of it.

As the sweltering heat continues to take its hold across Southeast Asian Region, I have been positive in noting that in the coming 2-3 days, another “Spring Storm,” is forecast to head towards Eastern China, and through Tuesday or Wednesday into the new working week, the Korean Peninsula and Japanese coast could expect another round of severe weather and dipping temperatures especially in higher elevations, more specifically in Sapporo and Hokkaido’s Northernmost tip this week.

Meantime, Hong Kong could yet again experience another week of severe weather as two (2) brewing storms off Central China has been developing for the last 24 hrs, and this could again spill some exceptionally supercharged atmosphere in the territory in the coming days, which the Hong Kong Observatory (HKO) has been closely monitoring its progress.

Flood Warnings For Mindanao, Scattered Thunderstorms Underway 

The Philippine Atmospheric Geophysical & Astronomical Services Administration (PAGASA), based in Quezon City, Philippines has been issuing a warning on potential flooding along Mindanao, as the trailing effects of the Intertropical Convergence Zone (ITCZ), and the prevailing High Pressure affecting Luzon. This was being reflected in their 0900Z (0500PM-PHL/MAL) advisory on Saturday, 22 April 2012, which the agency did not made mention of a surging “Front,” emanating from mainland China, which could spell some respite from the searing heat that has yet jumped to 38.9C on the same day in Tuguegarao City, in Cagayan Province, and Manila sizzled at 36C, which are based on the highest reading that was obtained at 0700Z (0300PM-PHL/MAL).

Based on the runs that I have been focused on, the surging “Cold air,” mass from the mainland China, colliding with the “Warm front,” from the East of the country could spell the “Orographic lift,” that could spawn some localized thunderstorm activity and increase convection along the coastlines of Palawan, Southern Visayas and Mindanao, and also along the West Philippine Sea, just West of Southern Tagalog Provinces and the Greater Manila Area (GMA) later today.

I am positive on this because the odds are getting better for “Rain showers,” in spots across the country’s Western seaboards and the Eastern coast of Mindanao and Visayas, specifically in Leyte-Samar Provinces, too. We’ll see about it later today when it finally happens.

Fig. 3.0 "An ominous thunderstorm activity which I took photo of on Sunday, 22 April 2012, 24-ft high above the ground over Iloilo City, Philippines. Image Courtesy: Weatherguy Adonis."

The problem I was encountering for almost two (2) years now is the absence of PAGASA’s Doppler Radar Imagery, which I have been consistently been campaigning them to officially open the said facility to public access considering the fact that it was bound to serve the greater purpose of educating most of the 92-million strong Filipinos in the country. I really don’t know why the weather bureau hides it from public eye.

I am calling the attention of the current administration, being led by His Excellency Benigno S. Aquino III, of the Philippine Republic, to look into this matter and forge a better organization within the system that governs the country’s weather bureau, whom enjoys a very unpopular reputation amongst majority of its constituency–the Filipino people deserve more from PAGASA, no more slump in forecasting capability, but an empowered workforce, better equipped agency with a primordial duty to protect its citizenry from the adverse effects of climatic challenges of perennial storms and recurring droughts.

Also, I have been monitoring the situation over Luzon, the rest of Southern Tagalog Regions for the last 48 hours, since we got some welcome rains here in Iloilo City on Saturday night, 22 April 2012, coupled with intense thunderstorm activity and rolling thunder across the horizon that could be heard from afar.

Malaysia Is Never Far

Based on the Global Forecasting System (GFS), a lot of tropical rainfall could be persisting especially along the near-Equatorial Regions of Asia-Pacific in the coming days, which include our fellow weather caster, Francis Chuah, from Kedah, Malaysia’s Northwesternmost Region is currently located.

Mr. Chuah has been reporting that at around 1300Z (0900PM-PHL/MAL), there has been lightning and some thunder rolling through the night sky, and as the night progresses further, at around 1545Z (1145PM-PHL/MAL), rains have finally fallen in his location. This was also confirmed by their Malaysian Meteorological Department (MalayMet), through Doppler Radar Imagery.

At the onset, there has been two (2) separate “Lows” affecting Malaysia Peninsula and Borneo, which could induce more tropical rains within the next 2-3 days in the forecast. Summer heat can become unbearable especially between early 0200Z (1000AM-PHL/MAL), and 0700Z (0300PM-PHL/MAL), which are mostly affecting the “Diurnal” episode of the convective processes of condensation and evaporation rate per area, that also would depend on the prevailing “Warm air,” and “Cold air” masses that collides which should provide an “Orographic lifting,” that provides the formation of Cb clouds, between low and high elevations. This process also allows the air masses to rise and cool down almost instantaneously as it generates “Humidity,” which result to “Precipitable” cloud formations, and on the most favourable of all conditions, it yields what we call, “Rainfall.”

BREAKING: Low Pressure Eyes Japan Once More, Welcome Rains Give Respite On Extreme Heat Across Philippines

By: Weatherguy Adonis

Adonis S. Manzan

Another Low Heading For Japan

Iloilo City, Philippines, 21 April 2012, (1240Z)–As Northern town of Hong Kong reels from the ill-effects of a “Tornadic” activity yesterday, 20 April 2012, which according to reports, several livestock and damages to property caused by the severe weather and damaging winds associated with a deep Low Pressure system that has yet again set its eyes on Western Japan as of posting.  Our meteorologist Robert Speta has made his analysis on the system earlier today, that “A deep low pressure system is now cruising across Korea and on to Japan today after bringing nasty weather to South Eastern China this past week. Even a report of a tornado occurred just North of Hong Kong.”

Currently, the Low Pressure system has already traversed over the Yellow Sea, just over the edge of Eastern China, that borders along Western seaboards of North and South Korea.

A recent ASCAT wind analysis yielding a 50+kt winds (92 km/hr) near the Ryukus Islands along the Southernmost tip of the Japanese Island chain. Early this evening, a “Front,” has been developing just moving past over Hong Kong, and has now propagated and surging along the Northernmost tip of Taiwan, and heading Northeastwards well into the North Philippine Sea.

A Ridge of High Pressure has been consistently pushing the Low system well into the Korean Peninsula overnight, with it are strong gusty conditions, severe thunderstorm activity and high seas. Meantime, the Western seaboards of Japan are now on watches for the incoming storm, just two weeks since the last one has hit the region.

Despite the system could bring nasty weather into the Japanese coast into Sunday, the authorities there have been warning its residents of dangerous sea and driving conditions ahead of the storm.

Welcome Rains, Thunderstorms Douse Unrelenting Heat Across Philippines

In the recent tropical activity along the Philippine archipelago, the sweltering heat was just staggering for the last 5 days, reaching to 38C & 39C in the country’s Northernmost tip of Cagayan, where in Tuguegarao City alone, the highest temperature was recorded at 39C on Friday, which made the sunnier days in Manila has been an uncomfortable 36C, making it more unbearable for most of the Filipinos.

Fig. 2.0 "A brief snapshot I made of the ongoing thundery rains persisting along Western Visayas tonight. Image Courtesy: NRL Mry."

On Saturday morning, 21 April 2012, an area of large convective precipitation has been earmarked to bring welcome rains along the Eastern sections of Mindanao, parts of Southern Visayas, and as we have confirmed today, we got rains here in Western Visayas region, where at around 1000Z (0600PM-PHL), thunderstorms loom over Iloilo City where I am located at the moment, and neighboring Iloilo Provincial towns to include Guimaras Island, which celebrate its merry “Annual Manggahan Festival,” on 15-22 April 2012.

The rains have been quite generous tonight, coupled with frequent thunder and flashes of lightning across the darkest of nights. I know that it won’t last until midnight but at least it has successfully provided some respite from the heat. I should say a lot of people are happier tonight.

The brewing storm was being observed since 0600Z (0200PM-PHL) today, there were feedback from Negros Island and Nueva Valencia, in Guimaras Island, that they too were getting some rains. That I thought strongly that rains could come our way and it did cooled the environs tonight.

The current wave of Intertropical Convergence Zone (ITCZ) has been pushing the precipitation well into a West to West-northwest trajectory across the Cental regions of the country well into Palawan Islands.

I do hope and pray that Luzon too will have its fair share of moisture through Sunday and Monday in the coming workweek as another “Tropical Wave,” has been spotted along a line of thunderstorms in the Pacific Ocean.

The Dawn Of A New Beginning: NHK World’s Newest Resident Meteorologist Robert Speta Debuts

By: Weatherguy Adonis

Adonis S. Manzan

Meteoric Leap, Empowering More People Across Asia Pacific, World

Iloilo City, Philippines, 09April 2012, (1430Z)–Long before I was entrusted this humbling experience of being an author here on Westernpacificweather.com, I have been amazed with the way Meteorologist Robert Speta was doing his Tropical Updates focusing more on Western Pacific Region for the last two (2) years.  There ain’t no other “American” guy you can find online that does these humbling stuffs and giving more emphasis on Asia’s weather but him.  His profound dedication and sheer honesty to his craft, and worth mentioning beyond his being accessibly friendly nature and blessed with the knowledge and proper training, there could be no doubt, he will do great wonders and an asset to NHK World’s sentinel of equally sensible and great team of forecasters we ought to see on television, heard on the radio and online.

Little did I know that Mr. Speta is a Broadcast and Operational Meteorologist rolled into one.  I could still remember his helpful video feeds from his website especially during times of great need like an approaching Typhoon about to affect my country, the Philippines back in 2011.

Additionally, he had seven (7) years of service with the United States Navy (USNavy), and now, he is engaged in anchoring the weather segment broadcast in Japan’s top-rating Newsline at NHK World Headquaters in Tokyo, effective today, 09 April 2012, Monday.

On 29 March 2012, I got an invite from Mr. Speta to join him in his vision of providing adequate information relative to what he loved of doing as a goal-oriented guy from Buffalo, New York in the USA.  Mr. Speta, where most of his friends call him, “Rob,” was no less like a young gun who wanted to make the world a safer, better place for the rest of us.

Mr. Speta, based on his career portfolio, is a seasoned, American Meteorological Society (AMS) Certified Meteorologist, who loved to carry on his mission by educating more and more people about the working relationship between climatic variables and effective understanding of what weather will be in the coming days, or what could be the areas affected by a singularly important aspect of life most of us do not fully comprehend but does form part an integral thread of our way of living.  It was beyond one’s dreams that brought a throng of people line into a particular calling.

Challenges Ahead

Time could only be a constant determinant of what’s to come for I was about to embark into a new dimension, a beginning of what I do best–writing articles that could provide credible, comprehensive information on what’s been happening around us, giving more weight on the study of Climatic dynamism and tropical cyclogenesis which affects the Western Pacific since time immemorial.

I am no professional in the study of meteorology, but with Meteorologist Speta at the helm of this vessel, I know we will go farther and reach ever closer to more people that deserve nothing less but dependable and adequate ideas and workable truths in today’s relatively unstable and elaborately extreme weather.

A good friend, a brother in the Philippines, shared his wisdom, in the person of Michael Williams, Sr. said to me on this day,“I take anything I associate myself with very seriously.  It only takes ONE good screw up to ruin a reputation, thus in many times, it cannot be recovered.”

In the light of these development, I also would like to thank Mr. Speta for the trust and continued support on my works here on Westernpacificweather.com, and considering that this could be this generation’s best, by far, in the last eleven (11) days that I have been engaged in this job, we are largely being viewed back home in the Philippines and abroad, especially in Malaysia via team mate and admin for this site, a fellow author and contributor in the person of whiz kid Francis Chuah and my fellow “Kababayan,” Ian Patrick Malejana, now based in Long Island, New York, USA.  These are smart people, make no mistake, they will deliver the goods the way it should be–piping hot, in-depth analysis and no nonsense.

Here are some of today’s cut on tube in case you missed today’s broadcast.  Enjoy as we did this afternoon at around 1720PM-JST, 0920Z (0520PM-PHL) during his first broadcast LIVE on air at posh NHK World Studios in NHK HQ in Tokyo, Japan:

Fig. 2.0 "On this screen indicate a possible flood potential for the regions of Yellow Sea bordering Korean Peninsula, that could spawn thunderstorm activity that could adversely affect the scheduled Ballistic/Rocket launch by Pyongyang, NoKor on 12 April and 16 April 2012. Image Credit: Weatherguy Adonis."

In today’s weather forecast, discussed the likelihood of yet another wet and windy weather by late Tuesday, 10 April 2012 across Western edge of Southern Japan, explains further the areas to be hit by another “Spring Storm,” this week, and advised locales to bring weather implements as a sort of protection against the elements, pointing out the possible rains across Southern China, that could spill into Yellow Sea as a developing Trough of Low could yet again surge into Sea of Japan, though not as intense as last week that hit Japan.

Moving on to the other side of the Pacific Basin, he laments of the incoming moisture coming from a huge Trough of Low along the Northwestern regions of the United States, and a brewing severe storm off the Southern regions, where a potential for damaging winds, severe thunderstorm activity and golf, tennis-ball sized hail pound the Mid-states of Oklahoma, possibly “Tornadic” activity in neighboring states as well into the next coming days and a potential for damaging winds, severe thunderstorm activity which is not a good situation out there.

In Europe, across the Baltic Region, an area of Low is fast approaching the British Isles.  Spain, however was hit by record drought conditions. Rains across Barcelona, Spain could provide a respite from the excessive heat as a surging area of Low that could cause Polar air into the Baltic Seas, further plunging temperatures across Europe and wet and windy conditions in the coming days.  Portions of the Netherlands to the South, and Norway to the North could be expecting some wet and windy weather associated with the system.  Italy could be getting some pounding rains and gusty wind conditions as an area of Low also lingers a bit off greater Italy and the Mediterranean countrysides.  Some thundery showers are also in the forecast.
To give you guys a gist of what’s to come, I give you Robert Speta, a fulfilled meteorologist ready to take on the world’s challenges!

Join us as we take the center stage using the most credible insights!
