The vernal equinox is of great significance in astronomy. On this day, the northern and southern hemispheres are divided equally day and night. Since then, the direct position of the sun has continued to shift from the equator to the northern hemisphere. The days in the northern hemisphere are longer than the nights, while the southern hemisphere is the opposite. In terms of climate, there are also obvious characteristics. In addition to the Qinghai-Tibet Plateau, Northeast China, Northwest China and North China, China has entered a beautiful spring.

In ancient China, the vernal equinox was divided into three periods: "First, waiting for the arrival of mysterious birds;" Second, wait for Lei Nai to make a sound; Third, wait for electricity.

The average daily temperature in all parts of China has steadily increased to above 0℃ except the mountainous areas in winter and the areas north of 45 north latitude. At this time, the cold has passed and the temperature has risen rapidly, especially in North China and Huanghuai Plain. The daily average temperature rises to above 10℃ almost at the same time as the rainy areas along the Yangtze River and the south of the Yangtze River, entering a bright spring.

From Mongolia to the northeast, there are often low-pressure activities and cyclone development. Low-pressure movement causes cold air to go south, and it is windy and windy in the north. When the long wave trough moves eastward, there will be continuous rainy and cold weather due to the intersection of cold and warm air masses. After the vernal equinox, the south began to enter a period of frequent strong convective weather. As the weather gets warmer and the soil thaws, the dusty weather in the northern region also increases.
