大气强迫日变化对东中国海海温模拟的影响
Impacts of Diurnal Forcing on Temperature Simulation in the Shelf Seas of China
摘要
Abstract
The diurnalatmosphericforcing has ability to change the horizontal gradient of sea surface temperature (SST) and enhance the vertical mixing between the surface and subsurface.Itis non-ignorable for the precise description of the upper ocean.In this study,the Regional Ocean Modeling System (ROMS) Model with the 4 times a day NCEP/NCAR forcing data has been used to investigate these kinds of impacts on the temperature simulation in the shelf seas of China.Comparing with the daily mean forcing,the diurnal forcing makes the model havea betterperformance.The diurnal forcing causes a decrease in net surface heat flux from the ocean about 13 W · m-2 in summer and an increase of it about 10 W · m-2 in winter,increasingthe temporal mean heat absorption in the shelf seas of China about 1.4.The high frequency diurnal forcinginfluences the vertical structure of the sea temperatureby the thermal and dynamic processes of the sea air interface.It leads to an increase of the mixed layer depth (MLD) about 10％,an increase of the mean temperature of the Yellow Sea Cold Water Mass (YSCWM) about 0.5 ℃ and a decrease of the meanvolume of the YSCWM about 1/3.关键词
