| Outline of Final Research Achievements |
The mechanism of the past regional climate around Japan and Asian regions was investigated. Recent increase of heat wave over Northeast Asia is associated with the land-atmosphere interaction and the decadal variation of atmospheric wave propagation running across the Eurasian continent. Over South Asia, recent change in monsoon circulation reduces the frequency of mesoscale convective systems, leading to the decrease in the heavy rainfall events. In Japan, observations show that extremely high water vapor amount rises corresponding to the air temperature increase. The analysis of geostationary satellites over more than twenty years demonstrated that the frequency of mesoscale convective systems increases when land surface temperature is heterogeneously distributed. The finding is expected to improve the prediction of severe storms which develops rapidly.
These results provide insights into the understanding of mesoscale and synoptic meteorological systems.
