Purpose of Review

What does recent work say about how changes in convective organization could lead to changes in extreme precipitation?

Recent Findings

Changing convective organization is one mechanism that could explain variation in extreme precipitation increase through dynamics. In models, the effects of convective self-aggregation on extreme precipitation are sensitive to parameterization, among other factors. In both models and observations, whether or not convective organization influences extreme precipitation is sensitive to the time and space scales analyzed, affecting extreme precipitation on some scales but not others. While trends in observations in convective organization associated with mean precipitation have been identified, it has not yet been established whether these trends are robust or relevant for events associated with extreme precipitation.

Summary

Recent work has documented a somewhat view of how changes in convective organization could affect extreme precipitation with warming, and it remains unclear whether or not they do.

对流组织变化程度作为极端降水动态变化的机制

 审查目的

最近的研究对对流组织的变化如何导致极端降水的变化有何看法？

 最近的发现

对流组织的变化是一种可以通过动力学解释极端降水增加变化的机制。在模型中，对流自聚集对极端降水的影响对参数化等因素很敏感。无论是模型还是观测，对流组织是否影响极端降水都对分析的时间和空间尺度敏感，在某些尺度上影响极端降水，但在其他尺度上则不影响极端降水。虽然与平均降水相关的对流组织的观测趋势已经确定，但尚未确定这些趋势是否稳健或与极端降水相关的事件相关。

 概括

最近的工作记录了对流组织的变化如何影响变暖引起的极端降水的某种观点，但目前尚不清楚它们是否会影响。
