Analysis of the Surface Flux Difference in Shenzhen Area before and after the Monsoon Rainfall
In order to further understand the influence of Southwest Monsoon on surface flux in Shenz-hen,the observed data of radiation from a meteorological gradient tower and a vortex covariance system were used to study the variation characteristics of surface flux in the process of heavy monsoon precipitation in this area.The results are shown as follows.During and after the monsoon precipitation,the solar radiation near the ground in Shenzhen weakened significantly and the albedo decreased.During the precipitation,the sur-face sensible and latent heat flux in Shenzhen were significantly lower(as a carbon source)than those before and after the precipitation(as a carbon sink).
