It has a great impact on agricultural production, transportation and so on. Among them, the autumn wind is an agricultural meteorological disaster in which the booting stage of rice occurs for three consecutive days from August to early September, and the daily average temperature is lower than 20 degrees, which leads to an increase in rice empty shell rate and a decrease in yield.
