China is bracing for a severe cold wave, with temperatures forecast to drop over 10°C below the seasonal average in many regions. Northern areas are particularly affected, with Shenyang expecting a 13°C plunge and Yinchuan set to reach lows of -8°C. Snowstorms have blanketed northwestern regions, with some areas reporting snow accumulation of up to 8cm.

The extreme cold is driven by a weakened polar vortex, allowing frigid air from the north to spread further south. This is compounded by the Siberian high-pressure system, which is funneling cold, dry air into China, intensifying the already low temperatures.

Snowstorms and Travel Disruptions

The cold wave has caused heavy snowfall in northwestern China, raising concerns about travel disruptions during the festive season. Additional snowfall is expected later in the week, which may further hinder transportation and holiday plans.

Cold Air Spreads to Thailand

The cold air mass over China has extended into Thailand, causing significant drops in temperature and strong winds. Northern, central, and eastern regions of Thailand, including Bangkok, have experienced 2-4°C falls, with northeastern areas seeing drops of 3-5°C.

Meteorologists have also predicted that the La Niña phenomenon will bring stronger winds, increased humidity, frequent thunderstorms, and cooler-than-average temperatures in the coming months.

Blizzard Conditions in Alaska

Meanwhile, Alaska is battling its own extreme weather, with heavy rain, strong winds, and snowstorms causing significant disruptions. Gusts of up to 70mph (116km/h) lashed southern Alaska, resulting in widespread flooding in low-lying areas.

Avalanche warnings have been issued for Turnagain Pass, Summit Lake, and Chugach State Park due to unstable snow conditions caused by a combination of intense winds, rainfall, and snowfall. Temperatures in Alaska are expected to plunge further by the end of the week, bringing the coldest polar air of the season.

Conclusion

The severe weather conditions in China and Alaska highlight the impact of climate phenomena like the polar vortex and La Niña. As these regions grapple with snowstorms, avalanches, and plunging temperatures, weather authorities continue to monitor the situation closely to ensure safety during this challenging period.
