Polarimetric signatures and hydrometeor classification of West African squall lines
Autor: Georges Scialom, Yvon Lemaître, Raquel Evaristo, Nicolas Viltard
Publikováno v: Quarterly Journal of the Royal Meteorological Society. 136:272-288
During the AMMA campaign, the Doppler and polarimetric radar Ronsard was deployed in Kopargo, Benin. In the present paper, three squall lines sampled during that period are described. It was the first time this type of system had been observed with a
