What are the climatic characteristics of Xiaoman solar terms? Will it be hot in Xiaoman?

The second solar term in summer. Xiaoman-refers to the summer crops with full seeds, but not yet mature, just small and not yet full. Every year from May 20th to 22nd, when the sun reaches 60 degrees, it is in full bloom.

Generally speaking, if the cold air in the north can penetrate into the south of China, and the warm and humid airflow in the south is also strong, it is easy to cause heavy rain or torrential rain in South China. Therefore, the late Xiaoman solar term is often the tense stage of flood control in these areas.

There is another saying in the middle and lower reaches of the Yellow River: "Xiaoman is dissatisfied, and wheat is risky." This "one risk" means that wheat has just entered the stage of milk ripening at this time, and it is very vulnerable to dry and hot winds, which leads to insufficient grain filling, grain shrinkage and reduced yield. There are many ways to prevent dry hot wind, such as building shelterbelts and spraying chemicals, which are all very effective measures.
