sensible atmosphere
1.Over the Tibetan Plateau, strong vertical diffusion resulting from intense surface sensible heat flux to the overlying atmosphere contributes most to the boundary layer heating, condensation associated with large-scale ascent is another contributor to the lower layer heating.
2.By using the gradient and Bruin methods, the ground surface sensible flux, which indicates the land?atmosphere interaction, is calculated respectively from the Large Aperture Scintillometer observed data and meteorological station data in Lezhi county of Sichuan Basin from 2000 to 2001. The monthly average of the two data is compared carefully.
3.Since the 1970s,the sensible heat flux and latent heat flux sent to the atmosphere from the Greenland Sea and the Barents Sea has increased,this is mainly due to the reduction of sea ice concentration and the weakening effect of insulator and shield of the solid ice accordingly caused by the increase of air temperature.
4.Soil temperature,moisture,and thermal and water fluxes between adjacent soil layers,obtained from ESES,were used for calculating exchanges of radiation,latent and sensible heat between soil surface and its immediately overlying canopy air. Data for model validation came from a southern study area(53°59′N,105°07′W) of BOREAS(Boreal Ecosystem-Atmosphere Study) located in Saskatchewan,Canada and beloging to temperate climatic zone.
