The beginning of the matter
In our impression, the winter in Heilongjiang is very cold, most of the time it is more than 20 degrees below zero, but the temperature in Heilongjiang has dropped rapidly in the past two days. It has reached minus 40 degrees Celsius. It is reported that this is the coldest day in Heilongjiang in 50 years. So do you know how this extremely cold weather is formed? Detailed analysis
Such a low temperature is mainly related to the cold wave. When the cold wave from the outside reaches a place, it will cause the temperature of the area to drop rapidly. Secondly, it has to do with geographical location. Heilongjiang is located in the northeast, facing the cold air from the outside world, so there are some changes in the outside world. It has a huge impact on the climate of Heilongjiang. Finally, because of the overall global climate, the temperatures this year are on the low side. It is reported that it may be related to the state of the equator. Written to everyone
Most parts of the country are suffering from the cold wave this year. Everyone must keep warm, drive safely on the way to work, be careful of slippery roads, and wear more clothes when going out to prevent frostbite. . At home, if you have a heater, turn on the heater, and if you have an air conditioner, turn on the air conditioner. Don't save a little money. Your body is your own, and you have to know that it costs more to get sick. Finally, I hope everyone will spend every day safely and happily in the new year. Related quotes

According to Tang Yuang, general salesperson of the Mohe Meteorological Bureau, the first reason for the extremely cold weather this year is that the northern polar vortex is weak, the Arctic air mass is squeezed, and the cold air breaks out southward, causing a large-scale cold wave The second is that the equatorial central and eastern Pacific is in a La Niña state, and the sea surface temperature continues to be abnormally cold. For China, it increases the probability of a cold winter. The third is that the meridional circulation of the mid- to high-latitude Eurasian circulation is strengthening, causing the polar cold air to accelerate. The impact moved southward, causing widespread cooling.
