What is the difference between spring and summer?

1. Spring: As far as solar terms are concerned, spring begins in the beginning of spring (February 2 -5) and ends in the long summer (May 5 -7).

2. Summer: the meteorological summer is from May 2 1 (Xiaoman) to August 22 (midsummer); In the south temperate zone, the meteorological summer is165438+1October 2 1 (light snow in the northern hemisphere) to February 18 of the following year (rain in the northern hemisphere).

Second, the astronomical integrity is different:

1, spring: The angle between the equator of the earth and its orbit is the fundamental reason for the seasonal change. In spring, the direct point of the sun gradually moves from the tropic of Capricorn to the north, crosses the equator after the vernal equinox, and the sun shines directly into the northern hemisphere. In spring, the distance between the earth and the sun is getting farther and farther. Every year around 65438+10.3, the earth is closest to the sun. Seen from the ecliptic plane, the sun is on the background of Aquarius, Pisces and Aries.

2. Summer: In summer, the direct point of the sun is always in the northern hemisphere. At first, it moved north, reached the Tropic of Cancer in the summer solstice, and then "returned" to the south. Summer is the longest sunshine season in the northern hemisphere, and there will be extreme days in the Arctic Circle, and the sun will not set all day. 1-3 In July, the earth will move to the farthest point of its orbit. Seen from the ecliptic plane, the sun is on the background of Taurus, Gemini and Cancer.

Difference three. Different weather:

1. Spring: As hot air begins to move northward and cold air often stays, the temperatures of land, water and air rise at different rates. Spring is the wettest season in many parts of the earth. There is famous Huangmei weather in the south of China, strong storms often occur in Europe, tornadoes in North America and windy weather in the north.

2. Summer: In May, China's coastal areas heated inland, and the formation of southwest depression led to southwest monsoon. The southwest monsoon reached China's coastal areas in May, when the northeast monsoon was blocked by the southwest monsoon and rarely affected in summer. It will not be affected until the end of August to mid-September. With the arrival of the first southwest monsoon, China has entered the summer.
