Influence of atmospheric forcing diurnal variation on sea-sea temper-ature simulation in east China
Abstract
The diurnal variation of atmospheric forcing can weaken the horizontal gradient of the sea surface temperature and strengthen the vertical mixing between layer and subsurface , to affect the simulation of sea temperature . article based on Regional ocean mode ROMS , with ncep/ncar published 6h 1 times ten m wind speed , shortwave radiation , Sea surface pressure etc re-analysis data , Research large effect of the diurnal variation of gas forcing on the temperature simulation of the East China Sea . is compared to the simulation of the daily average atmospheric forcing by the , , Daily Change atmospheric forcing The simulations and observations under are closer to . Atmospheric forcing changes to the sea of the East China Sea - Gas heat fluxes have significant effects , to make the East China Sea average annual sea and air heat fluxes Increase 1. 4 W / m2 , increase in summer W / m2 , reduce Winter Ten W / m2 . The diurnal variation of atmospheric forcing through the sea - the thermodynamic and dynamical processes of the gas interface affect the temperature of the Vertical structure , Strengthening the upper mixing of the East China Sea , make East China Sea mixed layer thickness ( MLD) add about 10%; The average temperature rise of the Yellow Sea Cold water regiment in summer 0 . 5 ° C , Body product reduction approximately 1/3.
