My academic expertise is in climate data analysis and dynamic mechanism examination of global and regional precipitation changes. Most of my research has focused on exploring how climate change affects precipitation changes in Taiwan (Table 1). In particular, I have conducted a series of studies to prove that the local afternoon rainfall events in Taiwan are affected by large-scale circulation changes on multiple timescales. The time scales covered by my research topics include: climatology, long-term trend, interdecadal variation, interannual variation, intraseasonal variation, and future projection.

The major achievement of this research group is to successfully investigate the characteristics and maintenance mechanisms of afternoon rainfall activities in Taiwan from a new perspective of changes in multiple timescales. For a long time, the afternoon rainfall convection in Taiwan has been regarded as a local event mainly modulated by changes in the local diurnal circulation. However, our research works show that the activities (frequency and intensity) of afternoon convective rainfall in Taiwan include long-term trend, interdecadal, interannual, and intraseasonal changes. These changes are not only regulated by changes in local circulation, but also by changes in large-scale circulation. In addition, through the application of global climate model data, our research works have demonstrated the possible impact of future atmospheric circulation changes on precipitation in Taiwan. These findings are very important for understanding how the precipitation in Taiwan can be affected by global climate changes. Recently, we have also expanded research interests to prove the ability of new satellite precipitation observations applied for research uses in Taiwan.
