京津冀夏季短历时降水气候分析

Climate Analysis of Summer Short-Period Precipitation in Beijing -Tianjin- Hebei Area

本文根据气象站夏季(6—8月)逐时降水资料的统计结果,分析了京津冀地区短历时降水气候概率和条件气候概率时空变化的特征,并给出城市热岛对降水分布的影响.这些工作为京津冀地区降水甚短期预报提供了气候背景.

In this paper, statistical results of the data of hourly precipitation at meteorological stations in summer (June- August) are used to analyze the temporal-spatial varations of climatological precipitation probability and conditional climatological precipitation probability in Beijing, Tianjin and Hebei, and the influence of the city heat island on precipitation distribution. This work will provide the very short-range forecasting of the precipitation in Beijing, Tianjin and Hebei with climatological background information.
