Observations of an 11 September Sahelian Squall Line and Saharan Air Layer Outbreak during NAMMA-06

(a) A horizontal constant altitude plan position indicator (CAPPI) image at 4.0 km altitude and radar height indicator RHI plots of the NPOL radar reflectivity (dBZ) along the leading convective line on 11 September 2006 at 0900 UTC. The negative sign in the CAPPI images indicates distance in the westward direction. The dashed line in the CAPPI image represents the location of the cross section. In the RHI images, ordinate axis is height z in km and the azimuthal is the distance in km along the cross-section. (b) A horizontal constant altitude plan position indicator (CAPPI) image at 4.0 km altitude and radar height indicator RHI plots of the NPOL radar reflectivity (dBZ) along the leading convective line on 11 September 2006 at 1000 UTC. The negative sign in the CAPPI images indicates distance in the westward direction. The dashed line in the CAPPI image represents the location of the cross section. In the RHI images, ordinate axis is height z in km and the azimuthal is the distance in km along the cross-section. (c) A horizontal constant altitude plan position indicator (CAPPI) image at 4.0 km altitude and radar height indicator RHI plots of the NPOL radar reflectivity (dBZ) along the leading convective line on 11 September 2006 at 1100 UTC. The negative sign in the CAPPI images indicates distance in the westward direction. The dashed line in the CAPPI image represents the location of the cross section. In the RHI images, ordinate axis is height z in km and the azimuthal is the distance in km along the cross-section.
