WSR-88D 4-Panel Storm-Relative Velocity Map (SRM) Image This is a four-panel display showing storm-relative velocity map (SRM) data over south-central Indiana. In this image, all panels represent data at the same time, but at four different radar elevation angles.  The upper left (lower right) panel shows data at the lowest (highest) altitude. For more information on WSR-88D velocity data, consult "Overview of the WSR-88D Radar System." Red (green) colors are winds directed away from (toward) the radar site (not shown, but located to the south of (below) the image area). The image shows low-level storm-relative inflow (light red colors over eastern Washington County) directed into a supercell mesocyclone (red-green rotational couplet) along the Jackson-Washington County border that produced a tornado. At high altitudes (lower right), storm top divergence is suggested.
