Climatic phenomena of arctic oscillation, polar front jet and super cold current viewed from wind

The cold current is particularly fierce. The Meteorological Bureau predicted that it was caused by the Arctic Oscillation, and made a video to let everyone know what the Arctic Oscillation is. Windyty is a network tool that can observe global climate and temperature changes. In addition to watching typhoons, the current Arctic Oscillation phenomenon can also clearly see the appearance of the Arctic cold wind heading south, which is more real and emotional than the educational film of the Meteorological Bureau. I will teach you a lesson this time.

According to Wikipedia, the polar front jet that limits the oscillation of the Arctic usually appears at a height of 7~ 12 km. First set the animation data to "temperature" on Windyty website, and then select the altitude above 8000m, and the following figure will appear.

The fast-moving airflow in the sky should be the so-called polar front jet, and the blue and purple blocks on the map are the locations of the cold air in the Arctic. Obviously, this cold air mass has covered the nearby mainland, South Korea and Japan, and Taiwan Province Province is just at the junction of the rapids. Although the influence of temperature is not as great as that of northern countries, we are fed up with rainy weather. Be sure to keep warm when you go out, and don't forget to keep ventilation indoors to avoid hypoxia and poisoning!
