Is the temperature higher or lower this year than in previous years? 202 1.

Compared with previous years, the temperature seems to be earlier this year. I read the news that the weather in 2020 will be more unusual than previous years. I wonder if the overall temperature this year is higher or lower than in previous years?

Is the temperature higher or lower this year than in previous years?

It is expected to be higher than in previous years.

Affected by global warming, the temperature in recent years is higher than before, and this year is no exception. And from the current point of view, the pace of winter in various regions seems to have slowed down. At present, most areas are still in a warm state in autumn, and the overall average temperature is about 20 degrees, which is warmer than last year. Therefore, it is expected that the overall temperature this winter will be higher than in previous years.

Why is the temperature so low in 2020?

It is normal for the temperature to be low occasionally.

The temperature will be affected by cold air changes, solar radiation, atmospheric circulation, ground conditions, ocean currents and other factors. For example, this year, due to El Nino, La Nina and other factors, there may be a big temperature change in a short time. For example, the cumulative cooling range in Harbin, Changchun and Shenyang is 65,438 10℃ or above on October 20th. The cooling range in Hohhot, Taiyuan, Beijing, Tianjin and Shijiazhuang is between 5-9.9℃; There is moderate to heavy snow in parts of Heilongjiang, Inner Mongolia, but it is sunny in most parts of the south, and the temperature is the same as in previous years. It can be seen that short-term weather changes are normal phenomena, which does not mean that the temperature has a downward trend throughout the year.

Why is the temperature abnormal in 2020?

1, La Nina phenomenon, which refers to the phenomenon that the sea surface temperature in the equatorial Middle East and Pacific Ocean is colder in a larger range than normal, and its intensity and duration reach certain conditions. Generally speaking, in the winter when most La Nina events occur, the latitude of the atmospheric circulation in the middle and high latitudes in Europe and Asia may increase, and the cold air activities affecting China are more frequent than normal, and the probability that the temperature in the central and eastern regions of China is lower than normal is higher.

2. Under the climate background of global warming, the factors affecting China's winter climate are more complicated, such as the melting of Arctic sea ice and the change of snow in Europe and Asia, which will all affect the variability of East Asian winter monsoon circulation, and then affect the winter climate anomaly in China.

At present, it is the time for autumn and winter seasons to change. It is very normal that the temperature is getting lower and lower at this time. Moreover, weather changes are closely related to people's lives and economic and social development. Many people are nervous at the sight of changes, which increases the feeling of abnormal temperature. In fact, it is no different from previous years. Pay more attention to changing clothes with the weather to avoid catching a cold.

When will the temperature begin to drop in 2020?

Every region is different.

If it is located in the north, the lowest temperature may have reached freezing point and heating has already started. However, in a few areas, such as Guangdong and Hainan, the temperature may be higher and not so cold. However, if most areas really want to enter winter, it will take five consecutive days for the average daily temperature to be equal to or lower than 10 degrees Celsius, and the temperature will drop significantly after the solar term in beginning of winter.
