Water vapor is a kind of greenhouse gas which has more powerful greenhouse effect than carbon dioxide.It supplies hydroxyl radicals to photochemical reaction in stratosphere.When the water vapor condensed into ices,the ozone will be consumed more quickly because the ices can supply heterogeneous interface to chemical reaction.The vertical transport by deep convective overshoot is one of the most important sources of stratospheric water vapor,thus the research of deep convective overshoot transporting water vapor into stratosphere can provide reference for climate change research.Some advances of water vapor vertical transport by deep convections are collected in the study,including evidences of water vapor injects into stratosphere,detection methods of deep convective overshoot,mechanism and influence factors of water vapor vertical transport.And some possible prospects are discussed in the end.
