Abstract

The article analyzes the characteristics of precipitation in the first and the second raining seasons in Guangdong province, and it founds that the precipitation changes violently after 90s.Through relationship analysis between SST of the North of the Pacific and the precipitation, the article founds that the precipitation in the first raining season is affected by the SST abnormality of last November-December in the keyl district(150 E~180° E,30° ~45° N),while in the second raining season it is affected by the SST abnormality of last May-July in the key2 district(140° E~20° W,10° ~15° N). The further analysis by singular value deposition (SVD)also proves this result, and it explains that the influence to the precipitation by SST is holistic in Guangdong province.
