As we all know, the factors that affect the price change of agricultural products are obtained through the production and processing of crops, and the growth and harvest of crops greatly affect the final output. Therefore, for agricultural products, seasonal and climate change are unique influencing factors, which are even greater than industrial and chemical products. With the large-scale and centralized development of agricultural planting, the influence of weather on agricultural output is increasing. The weather factor is beyond the control of the current level of science and technology. Therefore, the occurrence of extreme weather will inevitably affect the price fluctuation of agricultural products in the futures market. For example, the growth process of soybean is mainly divided into planting period, flowering period, filling period and harvest period. If the difference of precipitation and temperature in planting period obviously affects the growth of soybean seedlings, if there is little rain in filling period, it is easy to cause pod setting and insufficient soybean seeds. Therefore, the weather is a necessary consideration in the price analysis of agricultural products.
