- Abstract:
-
Based on the data of dust-storm occurrence times and time from 1954—2001 in Hohhot area, sandstorm occurrence rules were summarized and sandstorm occurrence impacting factors were analyzed to provide theory reference to dust-storm prevention and disaster reduction. Following results were founded though the research. The trend of sandstorm occurrence times was declining in recent 48 years in Hohhot area. But the dust-storm occurrence times appeared increasing trend and rapidly increased especially from the year of 2000. The period from afternoon to nightfall was frequently occurring stage though analysis dust-storm occurrence time. In the seasonal change of dust-storm occurrence of view, dust-storm occurrence duration and times were high in spring season, the most occur in April. The dust-storm occurrence times appeared rapid decrease and the lowest was in August and October. The dust-storm occurrence is correlated with precipitation, wind speed and the most vegetation coverage of the last year. It shows negative relation with precipitation and the most vegetation coverage of the last year and positive relation with wind speed.
