the measured records of the frequency changes in the four monsoon directions show that the average maximum wind direction appears counterclockwise from spring to winter every year, followed by SW→S→SE→N, and the static wind (C) has the highest frequency. In spring (March-May), the north wind gradually decreases and the southwest wind increases, which is an important factor of spring drought. According to statistics, the southerly wind in spring accounts for about 38% of all wind directions.
