摘要:

应用1991 ~2000年西北地Ix.基本站资料,统计分析了西北地区降雹的时空分布特征。结果表明:西北地区降雹主要的高频区在青藏高原中部、祁连山和天山山脉西段,并呈带状分布,多雹中心一般位于东西走向山脉的南坡,南北走向山脉的东坡。西北地区降雹旬、侯分布不均匀,产生双一多峰特征,从多雹区各代表站的旬或候际演变看,高原北部降冰雹来的比其南部旱且持续时间民,但降雹日数明显少于其南部。天山山脉、祁连山降雹盛发期处于波动状态而高原中部降雹盛发期比较集中。

Abstract:

 Based on the climatic; data of  ten years(1991一2000)China are analyzed.  The result show that the hail distribution is the spatial一temporal distribution(harac;teristi<、of hail in Northwest in belt patterns and the main hail zone is in the middle part of Tibetan plateau Qilian mountain and the west part of Tianshan mountain the more frequent、entre is in the south side along the east一WPSt mountains than that and the east side along the north一、outh mountains } the date o<(urrin} hails in mOthe south part of the plateau and the hail duration is lone but the hail days are the north part of Tibetan Plateau is earlier fewer than that in the south part of the plateau from the (urves of dec;adal and pentad evolution of hail days

Key words: northwest China, hail, temporal--patial distribution
