Climate type

Twenty-four solar terms are the product of agricultural civilization and the knowledge system formed by ancient ancestors by observing celestial movement combined with geographical climate and phenological laws. Agricultural production is closely related to geographical and climatic resources, and superior geographical and climatic resources are important conditions for the birth of agricultural civilization. China is located in the east of Asia-Europe continent and the west coast of the Pacific Ocean, with great differences in thermal properties between land and sea, forming the most typical monsoon climate in the world.

Monsoon climate is a mixture of continental climate and maritime climate. In winter, affected by the dry and cold air flow in the inland, the weather is cold, dry and rainy; In summer, it is hot, humid and rainy because of the warm and humid air currents in the ocean. Sufficient sunshine, abundant precipitation, high temperature and humid rain and heat coexist, which is a very superior climate resource in China. The high temperature period is consistent with the rainy season, and the water and heat are well coordinated, which is very beneficial to the growth of crops.
