Contribution of energy storage and vertical advection to the surface energy balance over oases
With the observational data located in an oasis at the Yingke site irrigation area of Northwest China and supported by the watershed allied telemetry experimental research project,the contribution of each energy storage term and vertical advection to the surface energy balance was analyzed.The results showed that after considering the total energy storage,the residual of energy balance (RES) was reduced with the maximum reduction between 09:00 and 12:00 of the local time,and the daily average of energy balance ratio (EBR) increased by 0.13 with a maximum increase of 0.23 between 07:00 and 09:00 and 0.09 from the canopy heat storage and the energy by photosynthesis.After adding the vertical heat advection into the energy balance equation,the root mean square of RES in the daily average underwent a reduction of 24.2 W/m2 with the maximum reduction between 12:00 and 15:00,and EBR increased by 0.07 with the maximum of 0.17 between 15:00 and 17:00,and 0.12 from the vertical latent heat advection.In contrast to the eddy correlation observations,the revised sensible and latent heat fluxes had witnessed reduction of about 16.5％ and an increase of about 7.4％ with the addition of the vertical sensible and latent heat advection.
