How long will it be hot this year?

Every summer, everyone thinks the weather is very hot. If you don't stay in an air-conditioned room, you will feel that the whole person is melting. Generally speaking, there is the hottest time in summer, and people will feel much more comfortable afterwards. Now it is summer, and many people are concerned about how long the high temperature in summer will last and how hot it will be this summer. Let's take a look at how many days and degrees the high temperature is expected to be in the summer of 20021year.

202 1 How many days is the high temperature expected?

As we all know, since May, summer has officially arrived. Although the season ends after August, due to the dog days and autumn tigers, the high temperature will not be bid farewell to until 10 at the latest, while in the south, the air will not drop until 1 1.

Generally speaking, the southern region begins to get hot in May, while the northern region may not get hot until June and July. 202 1 which month is the hottest? Generally speaking, it is in the midsummer in the dog days, that is, from July 3 1 to August 9.

For example, Guangdong, located in the south, usually starts to get hot at the end of May. The hottest month in a year is July, and the average monthly temperature in the province reaches 28 ~ 29℃. The extreme maximum temperature reaches 42℃.

In the northern region, although it has become hot in May, there will still be a week of low temperature after mid-May, and there will even be frost around May 15.

Is 202 1 a hot year?

202 1 may be a hot year, but the actual climate is the main factor.

After beginning of spring, the sunshine time will increase and the weather will get warmer. As the weather gets warmer, the cold air in the northern ocean of China will gradually decrease, and the water vapor in the northern ocean of China will fall on our land.

Therefore, after the water vapor in the north moved south, most parts of China were in a state of water shortage. Once the land is short of water, the evaporation of water vapor decreases after the sun shines. Because the water vapor in the air can continue to evaporate, the rainfall decreases and the temperature rises, which will accelerate the evaporation of water vapor on the ground. The more water vapor evaporates, the higher the temperature.

202 1 what is the predicted high temperature in summer?

This year, with the arrival of cold air in the south, the water vapor over the south has moved to the South China Sea, the surface water in the south is scarce, and the water vapor in the south has also decreased, so the warm and humid airflow is not obvious, and the water vapor in the south cannot be transported to the north.

So there will be many days of hot weather in summer. According to experts' prediction, the national high temperature forecast this summer is around 35 degrees, the highest temperature in some parts of the south is over 40 degrees, and the national average summer temperature is around 18C ~ 28, but the weather forecast is the main one.

202 1 In which month did the summer high temperature appear?

July and August

"Three volts" refers to the front, middle and back three volts, that is, from mid-July to mid-August every year. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are longer than the nights. Every day, the ground absorbs more heat than it emits, and the temperature near the ground is getting higher every day. During the "three volts" period, the heat absorbed by the ground is almost less than the heat emitted, and the weather is the hottest.

Later, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature slowly dropped. Therefore, the hottest time of the year usually occurs on the solstice in summer.

The hottest time in summer is 2-3 pm. At this time, although the sun is inclined to the west, the altitude angle is still very large, and the heat stored on the surface is still greater than the heat released, so that the temperature continues to rise, the local surface heat balance, and the surface temperature reaches its peak. After that, the heat released from the surface is greater than the stored heat, which reduces the surface temperature.
