Impacts of Different Onset Time El Niño Events on Winter Precipitation over South China

open access: yesAtmosphere, 2018
Winter precipitation over South China tended to be much higher than normal for the spring El Niño events during 1979–2016. For the spring El Niño events, the meridional and zonal circulations served as a bridge, linking the warmer sea
