Daily update- Tuesday, May 3, 2016

NWPAC outlook, 03 MAY

NWPAC outlook, 03 MAY

A strong spring storm slides through the north region and shares some of the energy with parts of the central region. Seasonal heat and humidity takes over in the south as the tropic region very slowly gets it act together. 

NORTH

A very strong spring storm system is rolling through eastern Asia today, en route to Japan by tomorrow. Parts of northeastern China, eastern Russia, and the Korean peninsula will see strong winds and occasionally heavy rain with the system as it moves to the east. Although Japan will get through today with no problems, it will start going downhill tonight as the system moves into the nation. For more on this spring storm system, check out Rob’s in-depth report. Elsewhere, with the majority of the energy located in the east, most of the north region is in a fairly stable weather situation today, with warm temperatures and sunny to partly cloudy skies.

CENTRAL

A cold front extending down from the strong spring storm system in the north region will bring a good chance for scattered thunderstorms across parts of southeastern China, and possible strong storms over eastern China, Taiwan, and the Ryukyu Islands. Moisture feeding into the system from the southwest is traversing southern China and northern Vietnam, helping fuel afternoon thunderstorms there as well. Temperatures are no surprise and will be seasonably warm across the region.

 SOUTH

It’s still quite hot in the south region, but we are far from the ridiculous numbers of April. Hottest locations will once again be parts of interior Indochina, and inland areas of the northern Philippines. Tropical moisture is settling into the region firmly, and the southern two-thirds of the region will see a good chance for showers or thunderstorms as weak tropical energy slides through.

 TROPICS 

Activity in the tropics appears to be taking a slow, gradual upward trend, which is climatologically normal, really, so it should not shock many. But, following the record season last year, in which we had already seen our 6th named storm, and were watching the development of our 7th taking shape at this point of the year, it has been utterly dead out there. SST’s (Sea-Surface Temperatures) are quite favorable, and increasing…overall, VWS (Vertical Wind Shear) is rather favorable…and moisture is in place, but is still depressed in terms of latitude, being relegated to areas below about 8 degrees north latitude. Although it’s not unheard of for systems to form below 5 degrees north latitude, it’s certainly a rarity early in a season’s development, due to weak Corliolis forces and a lack of sufficient wind convergence near the equator. All of this is resulting in a rather benign scenario for tropical development. All that being said, we see very little in the way of organized activity out there right now with just weak pulses of energy sliding along the I.T.C.Z. (Inter-Tropical Convergence Zone). One trough extends to the southeast out of the eastern islands of Micronesia; a second is draped in a NE to SW configuration from the same point of origin near Chuuk. A third is moving out of the southern Philippines, and the last is moving out of the WPAC near Malaysia. These impulses will bring showers and thunderstorms to these locations, while everyone else enjoys a warm, sunny day.

Daily update- Monday, May 2, 2016

NWPAC outlook, 02 MAY

NWPAC outlook, 02 MAY

Parts of the north region cool down after a very warm weekend, while unsettled weather continues across the central region. The heat is back on in the south following a weekend of rainy relief, and the tropics are heating up and starting to show a light resurgence. 

NORTH

A storm system moving through the north region is bringing down the temperatures significantly, as compared to the record-setting warmth of the past weekend. Rain-cooled temperatures will struggle to reach 20C (68F) today across Beijing, where weekend highs were at a record-setting 30C (86F). The current storm system will slide eastward across the region today, bringing clouds, rain and a few thunderstorms to most of eastern Russia, eastern China, and Korea, with increasing clouds across Japan through the day. Locations to the west and north will also see cooler temperatures today, with just a few scattered clouds.

Tokyo 22 17 72 63 Increasing cloudiness
Xi’an 26 11 79 52 Partly Cloudy
Shanghai 24 18 75 64 Thunderstorms likely

 

CENTRAL

The monsoon front is setting up well across the central region, as a train of weather systems from the west slide along the boundary between the very warm tropical air that is trying to work its way to the north, and the cooler continental air mass that has dominated the entire WPAC for the past 5-6 months. Fortunately, the latest pulse of energy has moved to the north of the central region, with only the easternmost locales seeing any chance for precipitation as a few scattered thunderstorms could pop up is southeastern China and Taiwan. Naha will see increasing clouds through the day as the impulse slides eastward, well to the north, but drags a bit of energy through the area in the next 24 hours. The remainder of the region will see a nice, warm day ahead, with lots of sunshine.

 SOUTH 

After a weekend of clouds and showers providing some relief to interior portions of Southeast Asia, the heat is ramping back up over the region under mostly clear skies. Shower and thunderstorm activity will once again be pushed to the south and west as tropical moisture moves westward through Malaysia and Singapore, and also through the southern Philippines.

 TROPICS 

The tropics are showing a slow turn towards a more active profile as we enter the month of May. Data shows that baseline conditions are quite favorable for development with high SST’s and low wind shear over the region. However, in the eastern half of the region, repeated impulses of weak, dry energy have been sliding down from the northwest and mixing in with the moisture below 10 degrees north latitude, and this has been drying out the overall profile of the atmosphere, which in short, is just not supplying enough fuel for the engine to get started. The song will remain the same according to long-range computer model forecasts, with no development expected. A few weak pulses of energy are drifting along the I.T.C.Z. (Inter-Tropical Convergence Zone) today with one located between the Marshall Islands and eastern Micronesia, and second, very broad, area of convergence rolling through the remainder of Micronesia, a third wave bringing much-needed rainfall to the southern Philippines, and a final wave abut to exit the region to the west near Malaysia and Singapore.
