%X The variations of cloudiness in five regions and the relationships between cloudiness and precipitation are analyzed. Decreasing trends in cloudiness were observed in most of the country, except the South China Coast and Southwest China regions. The ENSO and QBO time -scale fluctuations showed up in most regions. The oscillations of 3-4 year periods were very weak in the sixties and seventies and began enhancing in the eighties. It indicated a possible connection between the interannual variations of some meteorological elements and the long term climatic changes.
