Abstract. It is widely recognised that the variation of average surface chlorophyll a concentration (Chl) in South China Sea (SCS) closely related to wind forcing, especially during intense winter monsoon. In this study, we demonstrate after removal seasonal cycles, Chl showed strong asymmetric responses speed under El Niño or La Niña conditions. The analysis was based on time-series study area (115–117° E, 17–19° N) around SEATS (South-East Asian Time-series Study) station located central...
Abstract The rightward tendency (in northern hemisphere) of enhanced phytoplankton bloom often observed in the wake a tropical cyclone has commonly been attributed to bias mixing due stronger wind and wind‐current resonance. We demonstrated using high‐resolution biophysical model that vertical alone resulted only weak asymmetry after passage storm. was caused instead by decreased turbulence restratification submesoscale recirculation cells preferentially produced on right side, shift cool...
Abstract A significant poleward shift of tropical cyclones (TCs or typhoons) and TC‐induced storm surge in the western North Pacific has occurred recent decades. Here we use 64 year rainfall observations around Taiwan to provide an independent evidence shift. We show that, due island's unique location relative typhoon tracks, trends are significantly rising west north island but insignificant east southeast, caused by a preference decades for TCs veer more poleward. Analyses large‐scale...
Abstract In this study, we investigate the processes of phytoplankton growth and decline in mesoscale eddies western North Pacific Ocean based on situ chlorophyll data obtained from 52 cruises conducted by Japan Meteorological Agency together with idealized numerical simulations. Both observation model results suggest that chlorophyll/phytoplankton concentrations are higher cold than warm near‐surface water (z > −70 m). simulation, isopycnal movements associated upwelling/downwelling...
Abstract This study examines the spatiotemporal characteristics of diurnal precipitation over Luzon and nearby oceans in boreal spring. The focuses on exploring impact interaction between large- local-scale circulation changes modulation precipitation. We analyze satellite data obtained from Tropical Rainfall Measuring Mission Global Precipitation Measurement during spring (March–May) 2001–2019. results show that consists a clear eastward propagation signal. direction this is opposite to...

Abstract In the Malay Archipelago (Indonesia and Malaysia), forest is lost on large scales to cash-crop plantation (oil palm, rubber, acacia, including fallow lands) urban expansion. Deforestation changes land surface properties fluxes, thereby modifying wind rainfall. Despite expansive land-cover change over a climatically sensitive region of tropics, resulting impact Asian summer monsoon has not been studied. Here we study atmospheric response caused by island due deforestation into...
The hypothesis that a warm ocean feature (WOF) such as eddy may cause passing typhoon to undergo rapid intensification (RI), is, the storm’s maximum 1-min wind speed at 10-m height increases by more than 15.4 m/s in 1 day, is of interest forecasters. Testing challenge, however. Besides internal dynamics, intensity depends on other environmental factors vertical shear and storm translation. Here we designed numerical experiments exclude these factors, retaining only WOF’s influence change. We...
A new algorithm for modeling LED is proposed. We use normalized cross correlation to verify the validity of simulation in 1-D intensity pattern as well 2-D irradiance various mid-field distances.
