华北初夏高温低频特征研究

Study on Characteristics of Low Frequency High Temperature in North China during Early Summers

利用华北236个站气象观测资料,对华北初夏(6-7月)低频高温特征进行分析。结果表明:华北初夏高温主要表现为30~60 d的季节内振荡和10~20 d的准双周振荡特征。

Based on the meteorological observation data of 236 stations,the characteristics of low frequency high temperature during early summers(June to July)in North China are analyzed.It is found that the high temperature in north China during early summer has two periods of oscillation which are 30~60 d(intraseasonal oscillation(ISO)and 10~20 d(quasi-biweekly oscillation(BWO).
