30-day query of weather forecast in three northeastern provinces

Today, Xiaobian will share with you the knowledge of the weather in the three northeastern provinces, and will also answer the 30-day query of the weather forecast in the three northeastern provinces. If you can solve the problem you want to know, pay attention to this website.

Will the winter in 2022 be warm in the three northeastern provinces?

2022 is the year of La Nina. La Nina will lead to a cold winter, so the winter in the three northeastern provinces this year is a cold winter, not a warm winter.

La Nina refers to the phenomenon that the sea surface temperature in the eastern and central equatorial Pacific Ocean continues to be abnormally cold (just the opposite of El Ni? o phenomenon). According to the Department of Emergency Disaster Reduction and Public Service of China Meteorological Bureau, since July 20 10, the cold SST in the equatorial Middle East and Pacific Ocean has lasted for five months, and its comprehensive intensity has reached La Nina standard. The analysis of historical events shows that La Nina is beneficial to the strong wind in winter in China, which leads to the overall cold climate in winter and the dryness in North China and South China, which may lead to staged extreme low temperature events.

202 1 2022 is the year of La Nina. Because 202 1 is a double La Ni? a year, La Ni? a events occurred in the first half of the year -202 1 autumn and winter, entered La Ni? a state in 2021June, and a weak to moderate La Ni? a event occurred in winter.

La Nina meteorological principle:

The winter in 20021-2022 is expected to be cold winter, mainly because this year is still the "La Nina year", which means that the probability of cold winter in the south is higher than that in the north, so it is prone to extreme cold.

La Nina phenomenon is an abnormal cooling of seawater in the central and eastern Pacific Ocean. The southeast wind blows the seawater heated by the sun to the western part of the Pacific Ocean, causing the sea level in the western part to rise by nearly 60 cm compared with that in the eastern part, the sea temperature in the western part to increase, the air pressure to decrease, the accumulation of wet air to form typhoons and tropical storms, and the bottom seawater in the eastern part to flow backward, resulting in the cooling of the sea water in the eastern part of the Pacific Ocean.

There is heavy rain in Huanghuai in Northeast China and high temperature in South China. Why is the weather so abnormal this year?

There are two main reasons for the continuous high temperature weather: first, the water vapor conditions in the north are poor, the atmosphere is dry and the relative humidity is low; Second, controlled by the ridge of high pressure, the northwest downward airflow prevails at high altitude, the solar radiation is strong, and the high temperature weather begins to develop and strengthen. "In the future, the high temperature in the north will gradually weaken. After the subtropical high moves northward, it will mainly control the south of the Yangtze River and the central and eastern parts of South China, and the high temperature in the south will develop again, and there may be long-lasting high temperature weather.
