| Zusammenfassung |
| Long-term changes in rainfall and associated tropical cyclone (TC) activity
in transition seasons between the wet and dry seasons in South and Southeast
Asia, namely boreal spring and fall, were examined, using gridded rainfall,
TC tracks, and reanalysis datasets, the focus of discussion being the
long-term changes in coastal regions. It was found that long-term changes in
rainfall during the transition seasons in South and Southeast Asia were
closely associated with those in TC activity over the north Indian Ocean and
South China Sea. Rainfall in May increased in the last 40 years over and
around Myanmar, which indicates an earlier monsoon onset over the western
Indochina Peninsula. Rainfall over and around northern Vietnam also increased
in the last 40 years during October, which is known as the monsoon retreat
period. These increases were associated with the long-term changes in TC
activity. Furthermore, although linear trends have been previously suggested,
monotonically increasing or decreasing trends in these long-term changes were
not found over the last 60 years. |
