利用乌鲁木齐新一代多普勒天气雷达资料,对2003年7月～2005年6月的回波资料和5个气象观测站的地面资料中的云状、云量、降水量及降水时段资料进行对比分析,总结出层状云、对流云及混合云降水的时空分布特征。结果表明,层状云是乌鲁木齐地区降水的主要云系,降水次数明显多于对流云和混合云,混合云常常造成大降水,3类降水云的季节变化有明显差异。
Using the data of a new generation of Doppler weather radar in Urumqi, the data of clouds, cloud cover, precipitation and precipitation in the ground data of five meteorological stations from July 2003 to June 2005 were compared Analyze and summarize the spatio-temporal distribution characteristics of delamination cloud and convective cloud. The results show that stratiform cloud is the main cloud system of precipitation in Urumqi area, and the precipitation is obviously more than that of convective and mixed clouds. The mixed clouds often cause heavy precipitation, and the seasonal variations of three types of precipitation clouds are obviously different.
