[AAS02-02] Future Projections of Precipitation Characteristics around Japan in Early Summer Combining GPM DPR and CMIP5 Data: Analysis of multi-model variations
Consequently, future changes in precipitation are found to vary widely among the three types in association with the large-scale environments. More than 90% of models project an overall increase in small-type precipitation and northward enhancement of organized-type precipitation around Japan in the future. Multi-model variance of future projections of organized-type precipitation tends to be large corresponding to that of large-scale circulations such as the subtropical jet, while variance of small-type precipitation is affected by variations of both large-scale circulations and SST. It is revealed that the distributions of multi-model variations of future projections also differ among the three types in association with the large-scale environments.
