Brief Introduction

Guyu 谷雨 is the sixth of the 24 Solar Terms二十四节气. It begins when the Sun reaches the celestial longitude of 30° and ends when it reaches the longitude of 45°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 30°.

Grain Rain originates from the old saying, “Rain brings up the growth of hundreds of grains,” which shows that this period of rainfall is extremely important for the growth of crops. The Grain Rain signals the end of cold weather and a rapid rise in temperature.

Guyu 谷雨

Grain Rain is a solar term reflecting the phenomenon of precipitation. In the northern part of China, the first heavy rain usually occurs during this time of year, which is the peak time for planting rice, corn, and the growth of cotton.

Climatic Change

The main feature of Guyu is rainy. As the last solar term in spring, the rainfall frequently, and the humidity in the air gradually increases, which is conducive to the growth of crops. Entering the Grain Rain solar term, the precipitation increases significantly in the middle and lower reaches of the Yangtze长江 River and the south of the Yangtze River, especially in southern China, once the cold air meets the warm and humid air, it often forms a long-term rainy weather.

The Qinling–Huaihe Line秦岭淮河线is basically the dividing line between the spring rain in the south of the Yangtze River and the spring drought in the north. From the vicinity of the Qinling-Huaihe River to the north, the spring rain decreases sharply. In the north, Grain Rain is a symbol of the “final frost”. There are fewer cases of cold air invading the south, but the cold air activities affecting the north have not stopped, and early thunder will occur in many areas.
