Research Abstract

Intraseasonal oscillation of rainfall and convection over the land area (the Yangtze River Basin and the Yellow River Basin) of the East Asian monsoon were examined. Intraseasonal oscillation on 7-25-day timescales is dominated in the both basins, although there is large interannual variation. Mid-latitude Rossby waves primary factor to induce the intraseasonal oscillation of rainfall and convection.
