This paper is based on the planning and design of wan Jja valley reservoir .

本文系根据万家沟水库规划设计中的一些认识与体会而撰写的。

The character of water vapor transportation path in North China region in summer months ( JJA ) is very different from 1950 ′ s to 2000 ′ s.

华北地区1950&2000年代夏季（6~8月）逐月水汽输送轨迹变化特征明显。

On the interannual time scale , there exists significant positive correlation between the transient heat flux and the strength of jet stream in summer ( JJA mean ), June , July , August , respectively .

年际变化上，夏季平均和6、7、8各月平均的热量涡动输送和急流强度都存在显著的正相关。

Based on the canonical ensemble correlation prediction ( CECP ) model for seasonal precipitation anomaly , space-temporal characteristics between SSTA and summer ( JJA ) precipitation in China are analyzed , using various seasons and different regional sea surface temperature anomalies ( SSTA ) as predictor fields .

利用季降水异常的典型集合相关降水模式，分析了不同时段和不同区域的海温场与我国夏季（6-8月）降水之间的时空分布特征。

The secular trend and interdecadal variation of precipitation from June to August ( JJA ) in 1948-2001 over the Northern Hemisphere ( NH ), the Southern Hemisphere ( SH ), China , Eurasia , Africa , Australia , North America , South America and Antarctica are investigated .

研究了1948&2001年南、北半球及欧亚大陆、非洲大陆、澳洲大陆、北美大陆、南美大陆、南极大陆和中国7个大尺度区域6～8月降水的长期趋势变化和年代际变化。
