摘要
利用西北地区10个站近30年(1971—2000年)春季月平均气压与沙尘暴、扬沙、浮尘月发生次数计算分析了沙尘暴多发年、正常年、少发年春季地面气压场(距平均)特征差异,研究了中国西北地区春季扬沙、浮尘月发生次数与春季地面气压场的相关性。
By using the data of monthly average barometric pressures and the monthly frequency of sand storm,dust blowing and dust floating in springs in 1971-2000 in ten stations of northwest region,this paper analyzes the characteristic differences of spring surface pressure field among higher frequency year,normal frequency year and lower frequency year of dust storm,researches the correlation between the monthly frequency of dust blowing and dust floating in springs and spring surface pressure field in northwestern China.
