| Abstract: | The time and space distribution of windy weather and blowing dust weather in Henan Province was analyzed based on meteorological data of 121 meteorological stations in Henan Province from 1981 to 2010. There was a positive correlation between windy weather and blowing windy weather. The coefficient of correlation is 0.93. These two kinds of weather usually occur in spring and winter, but rarely in summer and autumn. In addition, as they differ in space distribution, windy weather mainly occurs in the central area of Henan Province and blowing dust weather usually occurs in the northern Dart of Henan Province and both sides of the Yellow River. |
