What effect does the weather have on agriculture?

The influence of weather on agricultural sustainable development is mainly reflected in meteorology and its derivative disasters. The frequency and severity of meteorological disasters in China are determined by its unique natural geographical environment and are closely related to social and economic development. Chinese mainland faces the Pacific Ocean in the east, facing the largest typhoon source in the world, and the Qinghai-Tibet Plateau in the west is the highest in the world. The land-sea atmospheric system interacts with each other and has a complex relationship. The weather situation is changeable, and various meteorological disasters occur frequently. China's topography is high in the west and low in the east, and the rainfall is unevenly distributed in time and space, which is easy to form large-scale floods and droughts. China has many conditions for breeding diseases, insects, rats and grasses. With the warming of climate and the aggravation of environmental pollution, biological disasters are quite serious. The mountainous areas, plateaus and hills in China account for more than two thirds of the country. Neotectonic movement and earthquake activity are frequent, and sudden geological disasters such as collapse, landslide and debris flow are almost all over the country. China is also a region with frequent agrometeorological disasters, such as drought, flood, chilling injury, hail, forest fire and frost. In addition, the technical level of agro-meteorological disaster prevention is limited, which makes China's agricultural production always in an unstable state and seriously restricts the sustainable development of China's agriculture.
