中文摘要: 为了建立长江中下游地区梅雨季节的新样本，采用以环流为主导的常规方法，利用
NCEP/NCAR逐日再分析资料及长江中下游5站降水资料，对2006年长江中下游地区梅雨季节的
特征量进行了诊断分析，并讨论了梅雨与夏季风的关系。结果表明，将6月5候和7月4候分别
划为2006年长江中下游地区梅雨季节的起始和结束时间是较为合适的；2006年长江中下游地
区梅
雨季节对应的梅雨量较常年偏少，这与梅雨季节中印度夏季风和东亚夏季风（包括南海夏季
风和副热带夏季风）强度较常年偏弱有关。

Abstract:In order to add new Mei Yu season sample in the Mid Lower Reaches of t
he Changjiang River, the daily data
of reanalysis from NCEP/NCAR and the precipitation observation of 5 stations i
n the Mid Lower Reaches of the Changjiang River are used and some routine met
hods based on circulation consideration
are adopted to diagnose the characteristic parameter of summer Mei Yu period
in the Mid Lower Reaches of the Changjiang River in 2006, and to discuss the
relationship between Mei Yu season and
summer monsoon in that year. The result shows that it is reasonable to ensure th
at the beginning and ending Mei Yu season in the Mid Lower Reaches of the C
hangjiang River are the 5th pentad of June and the 4th pentad of July respective
ly, also the total Mei Yu precipitation
of 2006 is below the normal due to the weaker Indo monsoon and east Asia mons
oon
(including summer the South China Sea monsoon and summer subtropical monsoon) o
f that season.
