New Estimate of Transport through the Taiwan Strait and Influence of Typhoons
The volume transport through the Taiwan Strait during the period 2005-2008 is estimated using a two-way nested 2D model forced by high spatio-temporal resolution meteorological data.On average,predicted monthly mean transports range from -0.38 Sv (December) to 2.02 Sv (June) and annual mean transport is 0.78 Sv.Compared with the estimates calculated from bottom-mounted and shipboard ADCP observations,these monthly mean transports seems more reasonable than previous results.Two contrast experiments have been conducted to figure out the possible causes of improvement in the transport estimate.One experiment run without air pressure demonstrates that including air pressure in the model has little contribution to the estimate of transport.The other experiment driven by multiyear-averaged monthly mean forcing data provides different monthly mean transports,particularly in winter,ranging from 0.03 Sv (December) to 1.87 Sv (July).In addition,it is found that typhoons have an evident influence on monthly mean transports in typhoon season and even on annual mean transport.High spatio-temporal resolution wind fields with a synoptic scale are necessary in order to improve the estimate of monthly and annual mean transports through the Taiwan Strait.
