Abstract:

By using a total of 49 years(1955~2003)duststorm data from 13 representative sites in Ningxia,We established a intensity standard of regional dust storm in Ningxia,divided extremely strong,strong,andordinary dust storm after 1955,and studied the time and intensity evolving features of Ningxia dust storm.By the analyse of temporal-spatial distribution features of sand stormsc ontrast to Gansu province,Some scientific basis of sand storm monitoring,warning,forecasting and preventing were provided for the east of Northwest China.

Key words: NingXia, sandstorm, divisive standard, feature difference

摘要:

选取宁夏13个代表站1955~2003年共49a的沙尘暴实测资料,确定了宁夏区域性沙尘暴天气过程强度标准,划分了1955年以来的特强、强和一般性沙尘暴天气过程,研究了宁夏沙尘暴过程的时间和强度演变特征,得出了一些新的认识。最后与上游甘肃省沙尘暴过程进行了时空分布特征的对比分析,为西北东部地区沙尘暴的监测预警和联报联防提供了一定的科学依据。
