A Radar Wind Analysis System for Nowcast Applications

Figure 3

Horizontal wind fields produced by the stand-alone RWAS at = 10 m in (a), = 500 m in (b), and = 1 km in (c) for the mesoscale front moved into the analysis domain at 025500 UTC on March 3, 2008. The color image in each panel shows the dealiased radial velocities at 0.5° tilt from the KTLX radar. The vector scale is the same for the three panels and is plotted at the lower-left corner of (b). The analysis domain size is 160 × 160 × 3 km³. The horizontal resolution is = = 2 km and the vertical resolution is = 250 m. The radial-velocity color scales are the same as those shown on the top of each panel of Figure 4. The green lines plot the county boundaries.
