NWPAC outlook, 8 MAR

NWPAC outlook, 8 MAR

Colder air continues to slowly work to the south through the north region, with sights set on the central region later this week. The heat continues to build in the south region, while the tropics see just a few clouds and showers scattered about. 

NORTH

A complicated weather scenario is playing out over the north region, as colder air slowly works to the southeast. Ripples of energy brought on by the combination of very warm air to the south clashing with the colder air mass will bring very changeable conditions to the region today. Let’s take a look at things from east to west: A strong storm system, the harbinger as I call it, is pulling away from Japan today, after serving up a good dose of clouds and showers to the nation yesterday. This system has “opened the door” for the other developments to take place over the next few days. Another stationary frontal system is settled parallel to the Japanese eastern seaboard, and will combine with the aforementioned storms system to drag the leading edge of the cool air to the east. High pressure is pushing colder air down from Siberia into central China, Korea, and eastern Russia, slowly, bringing a big downward shift in temperatures and allowing waves of energy to develop along it, bringing rain and even some snow to certain locations. Another strong ripple is expected to form near Shanghai later today, and slide to the east-northeast over Japan during the next 48 hours, helping to drag down the cooler air mass into parts of the central region.

Ulaanbaatar -14 (7) -27 (-17) Fair
Vladivostok 2 (36) -11 (12) Fair

Tokyo 21 (70) 11 (52) Partly Cloudy
Xi’an 10 (50) 3 (37) Cloudy
Shanghai 11 (52) 4 (39) Periods of Rain

 

CENTRAL

The central region is still quite warm, but all eyes are focused to the north, watching and waiting for the changes incoming later this week. The changes are helping to bring about some messy conditions across the central region as an old frontal system stalls to the southeast, and a new storm system gears up just to the north, near Shanghai. This new storms system will help pull the colder air to the south over the next 48 hours, with a noticeable drop in temperatures expected for most of the central region. Clouds, fog, and showers will affect most of eastern China and Taiwan, while the remainder of the region will see increasing clouds combining with the warm sunshine.

Taipei 27 (81) 18 (64) Scattered T-storms
Iwo To 18 (64) 7 (45) Partly Cloudy
Hanoi 31 (88) 20 (68) Partly Cloudy

 

 SOUTH

The south region continues to see the warmest temperatures of the entire NWPAC, as the sun’s angle gets higher with each passing day, allowing for slightly longer days, and more direct afternoon sunshine. It will be another scorcher across the region, and the Philippines, which has been getting lucky with the influence of the seasonal northeast monsoon, will not be spared from the heat. Part of the reason is the encroachment of a frontal system into the area, which is stalled to the north of the Philippines, with the warmest air located just to the south of the frontal boundary. The northernmost locations in the region will see sunshine with scattered clouds, while to the south, in Indonesia, Brunei, and Malaysia, a good chance for afternoon thunderstorms will be on the weather menu.

Brunei 31 (88) 26 (79) Thunderstorms
Singapore 33 (91) 27 (81) Thunderstorms

  

TROPICS 

With the strong El Nino still in place over the eastern Pacific, moisture and energy is suppressed in the tropics due to numerous intrusions of continental energy and the associated dry air. Once again, we find a day with weak ripples of convergent energy running along the weak I.T.C.Z. (Inter-Tropical Convergence Zone), with the strongest flare-up located in the Marshall Islands far to the east. Wake Island and the Mariana Islands will continue to see effects of continental energy sliding across the northern portions of the tropical region, with cooler temperatures along with a serving of showers and windy conditions for today.

Daily update- Monday, March 7, 2016

NWPAC outlook, 07 MAR

NWPAC outlook, 07 MAR

Very cold air returns to portions of the extreme north, poised to slide down into the remainder of the region this week. The central region will see another warm day as they prepare for a bit of a cool-down as well. The south continues to deal with intense heat, and the tropics stay mostly quiet. 

NORTH

Very cold air has moved into portions of northern China, Mongolia, and eastern Russia, as a cold Siberian high pressure area starts to migrate slowly southeastward. This colder air will slowly work its way across the north region during the early part of this week, bringing temperatures back down closer to normal levels. One weakening storm system is exiting the region to the northeast of Japan today. The trailing cold front will interact with moisture from a fairly potent storm system south of the archipelago, and moisture wrapping around this low pressure area will affect central and southern portions of the nation with clouds and rain showers. Overriding moisture will bring some clouds to the high country of China as well, but the remainder of the region will see a fairly pleasant day.

City High Temp C (F) Low Temp C (F) Conditions
Ulaanbaatar -14 (7) -28 (-18) Fair
Vladivostok 3 (37) -7 (19) PM Snow Showers
Beijing 11 (52) 4 (39) Fair
Seoul 15 (59) 0 (32) Partly Cloudy
Tokyo 18 (64) 12 (54) Rain
Xi’an 15 (59) 6 (43) Cloudy
Shanghai 24 (75) 11 (52) Fair

 

CENTRAL

Temperatures will remain warm across the central region for most of this week, before a cool-down takes place in the latter half. Considerable cloudiness is present across much of the region as moisture gets pulled to the east by a storm system exiting the region near Japan. Taipei will see rain fall as a result of this storm, but the remainder of the region will remain mostly dry for the time being.

Iwo To 17 (63) 10 (50) Cloudy
Hanoi 28 (82) 20 (68) Partly Cloudy

 

 SOUTH

The intense heat has eased up a bit across the Southeast Asian peninsula, for the time being, but it’s still dangerously hot over portions of the region today. Moisture being pushed in by the seasonal northeast monsoon will combine with a bit of energy to the north, and bring a few rain showers to portions of the northern Philippines. Scattered to numerous thunderstorms will affect Malaysia, Brunei, and Indonesia as waves of weak energy track along the much-retreated I.T.C.Z. (Inter-Tropical Convergence Zone) to the south. The remainder of the region will see just a few scattered clouds mixed in with the intense sunshine.

TROPICS 

The tropics remain mostly quiet, with just a few waves of weak convergent energy tracking along the I.T.C.Z. (Inter-Tropical Convergence Zone), which has retreated far to the southernmost latitudes of the region. Most of the energy that will affect the region is located far to the east in the Marshall Islands, where a few clouds and showers could erupt. Weak ripples of continental energy have once again begun to affect the Mariana Islands, and to the east, Wake Island, with cooler temperatures, clouds, showers, and occasional gusty winds on tap this afternoon. The remainder of the region will see a nice day, with plenty of sunshine and just a few scattered clouds.
