| Research Abstract |
Using global reanalysis data (JRA25/JCDAS) , ocean surface flux data (J-OFURO2) and various numerical models, we clarified (1) the overall features of explosively developing cyclone activity in the vicinity of Japan, (2) the combined effects of the East Asian winter monsoon variability and sea surface temperature (SST) fronts on the explosive cyclone activity, (3) the important roles of the explosive cyclones in extremely heavy snowfall/rainfall and freak-wave events, and also assessed (4) the long-term changes of the explosive cyclone activity associated with the occurrence frequency of the heavy snowfall on the Japan Sea coast under global warming. In addition, we constructed the database on the explosive cyclones and the associated natural disasters.
