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. 


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.

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.

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.

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.
