Abstract:
Based on the five station data in middle and north Ningxia from 1961 to 2000, the relationship between temperature in last winter and precipitation and frequency of sandstorm are analyzed. The results shows that the frequency of sandstorm in spring is corresponded with precipitation in last year and low air-temperature in winter. In March and April, it is also corresponded with the Asia circulation index. Because of the difference of their surface and peoples activity at each station, the correlation is obviously different too. As for various stations, their different correlation between the sandstorm frequency and Asian circulation in spring maybe just due to their different locations and surface conditions.
