HYDROMETEOR CHARACTERISTICS UNDER LAND-OCEAN AND URBAN-RURAL INTERFACES

Several SPOL systems have been installed in Brazil recently. Two SPOL dataset records of 2015 are used to characterize hydrometeors of convective systems under different boundary layer conditions over land, ocean, urban and rural areas of São Paulo and Espírito States. The hydrometeor and associated microphysics are explored by means of polarimetric variables such as ZDR and KDP to indicate CCN and differential heat effects under those four boundary layer types. The heat island effect in the metropolitan area of São Paulo produces very deep thunderstorms affected by a rich urban CCN boundary layer with distinct polarimetric variables overall features as high values of ZDR at lower levels and negative KDP aloft. The convective cells and their microphysics over land and ocean in Espírito Santo State indicate higher values of ZDR over the ocean as well as less developed convective cells. These analyses are carried out with summer 2015 datasets to establish a basic climatology of local e mesoscale features under these four boundary layers.
