内容 研究概要:In the field campaign of air-surface interaction in north-west China (HEIFE), surface flux measurements were carried out over complex land use area in arid region. The contrast between desert and vegetated oasis are remarkable in the surface radiation balance and surface heat balance, A large amount of radiative energy is released from desert surface and lead to less net radiation than the plant canopy surface. Most of the radiative energy absorbed by the oasis surface are released as the latent heat flux due to evapotranspiration. Another interesting finding is the diurnal variations of air temprerature and humidity. Air temperature over oasis surface are lower than over desert throughout a day and have larger amplitude of diurnal variation. The significant evening peak of vapor pressure is a characteristic over oasis in calm fine days.
