Why is it so hot recently?

It's so hot recently because in dog days, it is often said that it is "dog days hot", which is the hottest and hottest weather in a year. Three volts is the general term for initial, middle and final volts.

It is a well-known fact that it is hot in dog days, but do you know why it is the hottest in dog days?

We know that the sun is the source of heat and light on the earth. Without sunshine, there would be no warmth and seasonal changes on the earth, and all living things would not grow.

In summer, the sun is high at the zenith. Every summer, the sun shines directly on the Tropic of Cancer. At this time, the northern hemisphere gets the most sunshine, and the height angle of the sun is the largest. At noon, the sun is close to the ground. At this time, the thickness of the atmosphere through which sunlight passes is the smallest, and the light and heat of the sun are absorbed, scattered and reflected by the atmosphere, and more of them reach the ground, which is beneficial to the temperature rise of the ground. Secondly, in summer, the days are longer than the nights, the days are longer, the sunshine time is longer, and the heat absorbed by the ground is far greater than the expenditure, which makes the accumulated heat on the ground increase day by day and the temperature continue to rise. In midsummer, that is, in dog days, the accumulation of surface heat reaches its peak. In summer, there is much rain and high air humidity, and the heat capacity of water is much larger than that of dry air, which is also one of the important reasons for the sultry weather. In July and August, the subtropical high intensified. Under the control of subtropical high, the descending airflow inside the high makes the weather clear and partly cloudy, which is beneficial to sunshine and ground radiation warming.
