| 摘 要： | 利用2004年5、6月和2005年7、8月沈阳观象台的探空资料及棋盘山新一代天气雷达的三维体扫资料,应用压高方程和相对湿度与露点的关系,按不同温度、高度范围和温度露点差统计云体出现的频数,并对统计数据进行二元二次回归和历史拟合,得到沈阳地区夏季不同温度、高度条件下识别云体的温度露点差指标。将该指标与数值预报产品中的温度露点差值进行比较,即可得知未来沈阳地区的云顶相对高度范围和温度,进而判断未来降水云系的人工增雨潜力并制定人工增雨作业方案。

| Abstract: | With sounding data in May and June of 2004 and July and August in 2005 from Shenyang observatory and three-dimensional volume scans data from new generation weather radar in Qipanshan Mountain,the occurring frequency of clouds was statisticed from aspects of different temperature and altitude range and depression of dew point according to barometric height formula and relationship between relative humidity and depression of dew point.The dualistic and quadric regression and history matching of the statistic... |
