Daily update- Tuesday, March 29, 2016

NWPAC outlook, 29 MAR

NWPAC outlook, 29 MAR

Spring sticks around for another day across the north and central regions, as summer heat continues to build in the south. The tropics are still quiet, but conditions are shaping up for an active season. 

NORTH

Very warm, spring-like temperatures persist across the north region today. A couple of storm systems are sliding through, with the first very far to the east of Japan, pulling clouds and moisture away from the Land Of The Rising Sun, and a second weak system draped across northern China, Korea, and eastern Russia. This frontal system is quite weak, and will do nothing more than reinforce the northerly and northwesterly wind flow, doing little in terms of lowering temperatures in the near-term. Skies will be cloudy along, and ahead, of the front, affecting portions of central China from east to west, and bringing some showers to the Korean peninsula.

Ulaanbaatar 11 (52) -3 (27) Fair
Vladivostok 9 (48) -3 (27) PM Showers
Beijing 23 (73) 6 (43) Fair

Tokyo 18 (64) 9 (48) Fair
Xi’an 23 (73) 9 (48) Cloudy
Shanghai 23 (73) 14 (57) Cloudy

 

CENTRAL

Temperatures continue to edge slowly upwards across the central region, as mostly sunny skies dominate the majority of locations. Moisture being dragged in from the west ahead of a cold front in China will bring some clouds to southwestern China and northern Vietnam. The remainder of the region will see a nice day with plenty of sunshine.

Kunming 21 (70) 10 (50) Cloudy & Windy

Taipei 23 (73) 15 (59) Fair
Iwo To 17 (63) 16 (61) Fair
Hanoi 22 (72) 17 (63) Cloudy

 

 SOUTH

Intense heat continues to build in the south, with hotter days yet to come across the region. The northern island of Luzon in the Philippines is still feeling the effects of the latest late-season cool surge, with temperatures a bit lower than the rest of the region, and moisture polling up along the eastern coastal mountain ranges, helping provide some lift and squeeze out some showers. The southern Philippines will see moisture moving in from the east, helping enhance rain chances there as well. Singapore will see another round of scattered afternoon thunderstorms in the afternoon heat, but the remainder of the region will see lots of sunshine.

Davao City 34 (93) 24 (75) Showers
Brunei 33 (91) 26 (79) Partly Cloudy
Singapore 32 (90) 27 (81) Scattered T-storms

 

 TROPICS 

After a brief flare-up of convergence along the I.T.C.Z. (Inter-Tropical Convergence Zone) over the past 4 days, conditions appear to be quieting down a bit across the tropics today. No development is expected anytime soon, which is typical for a season following a strong El Nino event. A few showers will fall over portions of Micronesia and the Marianas but, all-in-all; it will be a nice day across the region.

City High Temp C (F) Low Temp C (F) Conditions
Guam 28 (82) 23 (73) AM Showers
Yap 32 (90) 25 (77) Partly Cloudy
Palau 32 (90) 23 (73) Partly Cloudy

Pohnpei 31 (88) 27 (81) Cloudy
Majuro 29 (84) 27 (81) Ptly Cloudy & Wind
Wake 26 (79) 23 (73) Ptly Cloudy & Wind

S.S.T.’s (Sea-Surface Temperatures) are increasing quite nicely across the region as we progress through the days of Spring, due to the increased sun angle and longer heating duration of each day. However, moisture is not very plentiful west of 150 degrees longitude, and south of 10 degrees north latitude. With the impulses of drier air moving in from the northwest over the next few weeks, this will inhibit any significant development in the mid-term.

Daily update- Monday, March 28, 2016

NWPAC outlook, 28 MAR

NWPAC outlook, 28 MAR

Cooler temperatures creep into parts of the north region, as the weather stays mostly nice across the central region. The heat cranks up once again in the south region, and the tropics pose no threat. 

NORTH

A bit of cooler air has started moving into the north region from Siberia, as a storm system migrates eastward across Mongolia, northern China, and into eastern Russia over the next 24-48 hours. Temperatures behind the frontal system are noticeably cooler, but moisture is scarce, therefore, precipitation is rather isolated. Another storm system is located to the east of Japan, and is moving away, but some rain showers are possible over eastern prefectures along a weak trough extending westward from the low pressure area located well offshore. The rest of the north region will see a nice day, with warm spring temperatures and plenty of sunshine.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar 4 (39) -7 (19) Cloudy
Vladivostok 9 (48) -2 (28) Partly Cloudy
Beijing 23 (73) 7 (45) Partly Cloudy

Tokyo 16 (61) 7 (45) Scattered Showers
Xi’an 24 (75) 10 (50) Partly Cloudy
Shanghai 19 (66) 9 (48) Fair

 

CENTRAL

Spring weather is well in place across the central region, as high pressure builds into the region and temperatures moderate within the high pressure area currently in place. A weak impulse of energy and moisture is located in the western extent of the region, bringing a few showers to western China. The remainder of the central region will see a nice day, with warming temperatures and just a few scattered clouds.

Iwo To 18 (64) 6 (43) Partly Cloudy
Hanoi 22 (72) 17 (63) Partly Cloudy

 

 SOUTH

The heat is back in place across the majority of the south region, as temperatures soar over Southeast Asia. Northern locales of the Philippines are seeing a bit of relief, thanks to a cool surge that has moved into the area. Some moisture will pool along the Sierra Madre Mountains, and the eastern seaboard, of the island of Luzon as the seasonal northeast monsoon get a bit of reinforcement with high pressure building in. Warm air advection is making for a hot day across the southern Philippines as well, with dangerously high heat indices expected in Mindanao. Singapore will see a few scattered afternoon showers today, but the rest of the region will see lots of intense sunshine and just a few scattered clouds.

Brunei 32 (90) 27 (81) Partly Cloudy
Singapore 34 (93) 27 (81) Scattered Showers

 

 TROPICS 

The tropics are mostly quiet, as weak wind convergence continues across the most southerly latitudes within the I.T.C.Z. (Inter-Tropical Convergence Zone). The convergent energy is draped along the entirety of the region from Micronesia to the Marshall Islands, but with no real focusing mechanism, rainfall will be sparse. Temperatures continue to be a bit cooler across northern locations within the region, as continental air masses affect these areas. Aside from mostly cloudy conditions in eastern Micronesia, everyone should see a pretty nice day with lots of sunshine.

Weekend update- March 26/27, 2016

NWPAC outlook, 26/27 MAR

NWPAC outlook, 26/27 MAR

The rebound is on for the north region as the central region holds steady to cooling slightly. Portions of the south are seeing a break in the intense heat and the tropics look just a tad busier today.

NORTH

Temperatures will trend upwards this weekend across the north region, as return flow for high pressure pumps in warmer air from the south. A weak cold front is draped over Mongolia, and will slowly slide southeastward over the coming days. The entire north region, south of this frontal system, will see a great weekend, with fair to partly cloudy skies and warm spring-like afternoon highs.

CENTRAL

Changeable weather conditions persist over the central region, as residual moisture from the latest storm system, and the jet stream, help bring some cloudiness and showers to parts of the region. Temperatures will hold steady across the region this weekend, as the air mass associated with the latest surge moderates a bit. A new weather system to the west will help kick up some showers in west-central China and bring clouds to northern Vietnam on Sunday. A few showers will also fall across portions of eastern China and Taiwan on Sunday.

 SOUTH

A new late-season surge of continental air is slowly working its way through the Philippines this weekend, bringing some much-needed relief from the heat to the northern half of Luzon. However, the remainder of the region continues to bask in the summer-like heat, with no end in sight. Warm air advection south of the surge will keep it hot over Southeast Asia and the southern Philippines, and increased moisture riding along the I.T.C.Z. (Inter-Tropical Convergence Zone) will bring some rainfall to the southern Philippines, Indonesia, Brunei, Singapore, and Malaysia through the weekend.

TROPICS

The tropics appear to be ramping up in terms of general activity as moisture increases south of the 10th parallel region-wide. MIMIC-TPW (Total Precipitable Water) loops show a plume of moisture extending to the northwest from the equator, between 150E and 135E, migrating westward along the I.T.C.Z. (Inter-Tropical Convergence Zone). This moisture will impact western locales early next week, enhancing rainfall possibilities. Satellite photos indicate a series of weak waves of convergence in the region, one over Indonesia and Brunei, the second over western Micronesia, a third in Eastern Micronesia, and the last out near the Marshall Islands. The ripples of energy will enhance rainfall possibilities this weekend for the entire region, but long-range computer models are showing nothing in the way for development.
