季风循环是水蒸汽运输的一个重要搬运人,并且它象水蒸汽平衡一样通过大规模水蒸汽运输和分布的限制和控制影响 monsoonal 区域的降水。关于在在东方季风中国上的降水的稳定的氢和氧同位素的全面研究能有益于 monsoonal 降水机制的全面理解。在降水(CHNIP ) 的同位素的中国网络的十七个地车站被选择了在年期间收集每月合成的降水样品 20052006。D 和 18O 的部件被分析了完成空间与时间的分布。当同位素输入越过这个区域工作,基于 274,获得的月刊取样的确定的本地大气的水线 D=7.46 18O+0.90 能被对待,由于基本上反映在东方季风中国上的特定的地区性的气象学的条件。价值弄空从对内部区域沿海。在南部的中国和东北中国,有 18O 的典型周期的模式。不同主导的影响度量衡学的因素与不同区域被提起了。从南方到北方, 18O 的温度效果提高了,当数量效果从在南部的中国在 all-year-scale 存在到在在诺思中国和东北中国的主要雨季期间仅仅是显著的变化了时。主要地理控制在东北中国在南部的中国和诺思中国从高度变化了到纬度。而且, 18O 有进展的一个含意和季风以及降雨带转移的撤退。18O 也是为台风和热带暴风雨的运动路径的 tracer。
Monsoon circulation is an important carrier of water vapor transport, and it impacts the precipitation of the monsoonal regions through the constraints and controls of large-scale water vapor transport and distributions as well as the water vapor balance. An overall research on stable Hydrogen and Oxygen isotopes in precipitation over Eastern Monsoon China could benefit a comprehensive understanding of the monsoonal precipitation mechanism. Seventeen field stations of the Chinese Network of Isotopes in Precipitation (CHNIP) have been selected to collect monthly composite precipitation samples during the years 2005-2006. Components of δD and δ^18O have been analyzed to achieve the spafiotemporal distributions. The established Local Meteoric Water Line δD=7.46δ^18O+0.90 based on the 274 obtained monthly samples could be treated as isotope input functions across the region, due to basically reflecting the specific regional meteorological conditions over Eastern Monsoon China. The 8-value depleted from coastal to inner area. In Southern China and Northeastern China there were typical periodic patterns of δ^18O. Different dominant affecting metrological factors have been raised with different regions. From south to north, the temperature effect of δ^18O enhanced, while the amount effect changed from existing at an all-year-scale in Southern China to being only remarkable during the main rainy seasons in North China and Northeastern China. Main geographical controls varied from altitude in Southern China and North China to latitude in Northeastern China. Furthermore, δ^18O had an implication of advance and retreat of the monsoon as well as rainfall belt transfer. δ^18O was also a tracer for the movement path of typhoon and tropical storms.
