What are the changes in the rainy weather in February/2002/KLOC-0? Introduction of rain weather changes in 202 1 February.

1, the rain solar term means entering the spring in the meteorological sense. After the "rain", the temperature in most parts of China rose to above 0℃, the daily average temperature in Huanghuai Plain reached about 3℃, the average temperature in Jiangnan was about 5℃, the temperature in South China was above 10℃, and the average temperature in North China was still below 0℃.

2. Before and after rainfall, rape and winter wheat generally turn green and grow, which requires high water content. "Spring rain is as expensive as oil", so proper precipitation is particularly important for crop growth. At this time, the precipitation in North China, Northwest China and Huanghuai areas is generally less, which often cannot meet the needs of agricultural production. If there is little rain in early spring, the best economic benefit can be obtained by timely spring irrigation before and after the rain.
