Case Study of Squall Lines Passing Over Dakar Using NOAA Sounders

Squall Lines (SL) are fast and well organized mesoscale convective systems. These phenomena of primary importance have been the subject of numerous studies, mainly descriptive and dynamic. Applications made of satellite data for the study of Squall lines are mostly descriptive. The advantage of ATOVS data is that they provide a vertical view of the atmosphere by considering wavelengths. Thus we made a study of the atmosphere subjected to the passage of squall line with these data. In this study, five passages of squall lines allowed us to show the radiative signature of SLs with ATOVS data.
