Radar CAPPI's for 990223


This page contains CAPPI images (gif format) of reflectivity and storm relative winds for the 990223 event. These images have the UND Citation and NASA ER2 flight tracks overlaid (solid and dashed lines, respectively). The flight tracks split the 20:50 and 21:00 UTC radar volumes.

Note that the absence of dual Doppler winds in the north west portion of the convective region is due to lack of coverage by the TOGA radar. Reflectivites shown below are from the S-pol radar (click here to compare the 2 km level cappi from the TOGA radar at 21 UTC). Also, gaps in the data above 6 km at far range (i.e., greater than 100 km) are due to the lack of sufficient number of points for mapping the radar data to a cartesian grid (click here for more information on the effect of gridding on the dual Doppler analysis).
