Abstract：
The research focused on finding the roles of oceanic mesoscale variability in changing the oceanic and atmospheric environments in/over some sea areas around Taiwan, where are rich of oceanic mesoscale variability. During the periods when large-scale sea-surface-temperature (SST) fronts were strong, the oceanic mesoscale variability (including ocean eddies and Kuroshio intrusions) would change the spatial distribution of SST significantly, forming some tongue shapes of warm and cold SST through horizontal heat advection.
Corresponding to the warm and cold SST tongues, sea surface wind was highly uneven in spatial distribution. Its speed was faster over the warm SST tongues but slower over the cold SST tongues, than the surrounding areas. The non-uniformity of SST and sea surface wind could move with the eddy motion in space and co-vary with the Kuroshio intrusions in time, having a possibility of affecting the local rainfall. These findings from satellite observations give us an opportunity to study the roles of oceanic mesoscale variability in ocean-atmosphere interaction on weather timescales.
