Intraseasonal reversal of climate has been remarkable in recent years, such as: reversed or alternating extreme cold and extreme warm events or extreme dry and extreme wet in different months or in different stages of the season. There are much challenge in climate prediction  because the intraseasonal climate variation is often within the seasonal mean variation. It is therefore urgent to understand the intraseasonal variation of climate, to identify its predictability and predictive sources, and to propose effective prediction methods and prediction models for it. We review the progresses in research during the last five years on the main characteristics, physical processes, mechanisms, predictability, and prediction of intraseasonal variation of climate in China.
