Weather tracker: cold wave sweeps China as new year approaches

Temperatures in some areas could fall to more than 10C below seasonal average. Plus, blizzard fears in Alaska. China was hit by snowstorms and a significant cold wave over the weekend, and the extreme conditions are expected to persist as the country approaches the new year on Wednesday.
Temperatures are forecast to drop to more than 10C (50C) below the seasonal average in some areas, with northern regions experiencing the most severe weather. Maximum temperatures in Shenyang are expected to plummet by more than 13C, while Yinchuan could tumble to -8C.
Snowstorms have been affecting north-western China, with accumulation reaching 8cm in some areas. Additional snowfall is expected later this week, potentially disrupting travel during the festive period. The cold wave is primarily caused by a weakening of the polar vortex, allowing cold air from the north to push farther south. This is exacerbated by a high-pressure system known as the Siberian high, which is funnelling cold and dry air from Siberia southwards, trapping it over the region and intensifying the drop in temperatures.
The high pressure and associated cold air over China has extended south into Thailand, triggering a notable fall in temperatures and strong winds in the country. Northern, central and eastern Thailand – including the capital, Bangkok – have experienced temperature drops of 2-4C, with 3-5C in the north-east.
According to the national meteorological department, the La Niña phenomenon is likely to bring strong south-easterly winds in the coming months. This will cause increased humidity, a higher frequency of thunderstorms and cooler-than-average temperatures.
