| 摘 要： | 利用2006年NCEP/NCAR再分析资料和广东省86个测站的逐日降水资料,分析了广东汛期降水的大气环流低频特征.结果表明,华南汛期的降水主要有7～20天和60天左右的周期振荡,广东汛期的明显降水过程主要出现在60天左右低频振荡的正位相中,当7～20天振荡与60天左右的低频振荡正位相同相叠加时,广东降水明显增强.前汛期...

| Abstract: | In this paper,the characteristics of atmospheric low-frequency oscillation over Guangdong during the rainy season in 2006 are studied by using the NCEP/NCAR reanalysis data and daily precipitation data of 86 stations in Guangdong.The results are shown as follows.Heavy rainfall mainly occurs in the positive phase of a 60-day low frequency oscillation;when the positive phases of oscillations with periods of 7~20 days and 60 days appear at the same time,the precipitation increase significantly.Analysis of the ... |
