What's the matter with such hot weather?

The earth's orbit around the sun is elliptical, and the distance between the sun and the earth is constantly changing. Every year, 65438+10.3 is the latest day, and July 4 is the farthest day. It should be hot in June and cold in July, but the actual situation is just the opposite.

In fact, it is the angle of the sun that really determines the heat and cold on the earth. Because the earth revolves around the sun obliquely, the angle at which the sun shines somewhere on the earth will change constantly. In summer, the sun shines directly in the northern hemisphere; In winter, the sun sets in the northern hemisphere. For the same amount of sunlight, direct sunlight is smaller than oblique sunlight. Then, in the same size place, when the sun is in direct sunlight, it is hot when it receives more sunlight; When the sun is slanting, it receives less sunlight, so the weather is naturally cold.
