Abstract:

85-station daily precipitation data from 1961―2010 provided by the National Meteorological Information Center and the NCEP/NCAR 2010 daily reanalysis data are used to investigate the low-frequency variability on the precipitation of the first rain season and its relationships with moisture transport in South China, and channels of low-frequency water vapor transport and sources of low-frequency precipitation are revealed. The annually first raining season precipitation in 2010 is mainly controlled by 10–C20 d and 30–C60 d oscillation. The rainfall is more (interrupted) when the two low-frequency components are in the same peak (valley) phase, and the rainfall is less when they are superposed in the inverse phase. The 10–C20 d low-frequency component of the moisture transport is more active than the 30–C60 d. The 10–C20 d water vapor sources lie in the South India Ocean near 30° S, the area between Sumatra and Kalimantan Island (the southwest source), and the equatorial middle Pacific region (the southeast source), and there are corresponding southwest and southeast moisture transport channels. By using the characteristics of 10–C20 d water vapor transport anomalous circulation, the corresponding low-frequency precipitation can be predicted 6 d ahead.
