| 摘 要： | 大气中的水汽是大气中重要的组成部分,水汽含量在人类日常生活中扮演重要的角色,大气水汽含量探测工作对于水汽循环、水汽输送、人工降水以及水资源评估等气象研究具有重要意义。本文对高质量的欧洲中期数值预报中心(ECMWF)再分析资料的进展进行了介绍,并且利用该资料对天津地区水汽含量的时空变化进行了分析,研究发现水汽含量的变化具有明显的季节性,受季风的影响显著。在空间分布上,天津上空水汽含量呈现从东部沿海往西部内陆地区逐步均匀减少的趋势,并且其上空的水汽含量呈现逐年增加的趋势,水汽含量的增加可能和温室效应有关。

| Abstract: | The water vapor is an important component of the atmosphere.The water vapor content plays an important role in human daily life.The detection of atmospheric water vapor content is of great significance for meteorological research such as water vapor circulation,water vapor transport,artificial precipitation,and water resources assessment.This paper introduces the progress of high-quality ECMWF reanalysis data,and uses the data to analyze the temporal and spatial variation of water vapor content in Tianjin.The study found that the variation of water vapor content has obvious seasonality,which is affected by monsoon.In terms of spatial distribution,the water vapor content over Tianjin gradually decreased from the eastern coastal to the western inland.Besides,the water vapor content showed an yearly increasing trend,the increase of water vapor content may be related to the greenhouse effect. |
