Will it be cold in winter from 2020 to 20021year (will it be cold in winter from 202 1 2022)?

The winter of 2020 has arrived, and the weather is getting colder and colder. In recent days, the weather has been particularly cold. So many people say that this year is a cold winter. 2020-202 1 Will it be cold in winter? Is it true to enter the extreme cold era in 2020?

2020-202 1 Will it be cold in winter?

It will get cold.

According to the research of the Meteorological Bureau, there are three major factors that can indicate that this year is the cold winter of 2020-202 1 year. First, the extreme low of sunspots will last for the third year in 2020; Secondly, 2020 is the possible year of La Nina; And PDO will return to the cold phase in 2020; According to the current analysis of the earth's air and sea, the probability of PDO cold phase and La Nina event forming next year is high, and various indications show that the winter in 2020-202 1 year will be cold.

Is it true to enter the extreme cold era in 2020?

It depends on the actual situation, and there is no scientific basis at present.

According to the data released by the American Climate Prediction Center, La Nina phenomenon has been formed in 2020, and the temperature this winter will be lower than in previous years, but in fact, it has little change in the overall global winter temperature.

The main reason is that under the general trend of global warming, even under the influence of La Nina phenomenon, it will not enter extreme cold. However, because winter lasts for three months, it is also very common to have short-term extremely cold weather due to meteorological changes.

At this time, people are generally advised to pay attention to the weather forecast in time, pay attention to recent weather changes, increase or decrease clothes according to temperature changes, adjust travel measures, and prevent cold and freezing.

The latest news of La Nina in 2020

According to the latest weather, the development of La Nina phenomenon in the second half of 2020 is a foregone conclusion, and its intensity continues to increase after its formation, which has a great impact on the global climate.

Generally speaking, the year when La Ni? a phenomenon develops will lead to the global temperature drop. China's climate is prone to low temperature, and it is more likely to have a cold winter. However, the specific situation cannot be accurately explained, because there are not a few climatic phenomena affecting China, which need to be determined according to the specific situation.

What is La Nina phenomenon?

La Nina phenomenon is an abnormal cooling of seawater in the central and eastern Pacific Ocean. Mainly due to the southeast wind, the seawater heated by the sun was blown to the western Pacific Ocean, causing the sea level in the west to rise by nearly 60 cm compared with that in the east. The sea water temperature in the west rises, the air pressure drops, the wet air accumulates to form typhoons and tropical storms, and the bottom sea water in the east hangs upside down, which makes the sea water in the eastern Pacific cool, which belongs to the phenomenon that the sea surface temperature continues to be abnormally cold.

The symptoms of La Nina phenomenon are hurricane, rainstorm and severe cold, and it and El Ni? o phenomenon will cause serious global climate anomalies.
