![]() We will present preliminary wind retrieval results using these refined techniques. High Resolution Version National Radar Sites Static Image Loop Alaska Guam Hawaii Puerto Rico. Using multi-Doppler and in situ data gathered from the 2017 field phase of the VORTEX-SE project, we are working to refine and improve the accuracy of three-dimensional wind retrieval solutions through incorporation of surface mesonet data and lower boundary conditions representative of terrain features in the southeast. Extrapolation assumptions that are error prone even in these relatively flat conditions are more problematic in areas with more complex terrain and varied vegetation. See the latest Iowa Doppler radar weather map including areas of rain, snow and ice. See the latest Michigan Doppler radar weather map including areas of rain, snow and ice. Multiple-Doppler wind retrievals in severe storms, which can contain intense horizontal convergence and updrafts near the ground, often are performed for storms targeted in relatively flat and vegetation-free regions of the Plains. See the latest New York Doppler radar weather map including areas of rain, snow and ice. Central Europe Lightning Radar Southeast Europe Lightning Radar. High resolution images of US radar locations with archive back to 1991: Base reflectivity, base velocity, storm tracking. See the latest Virginia Doppler radar weather map including areas of rain, snow and ice. ![]() Accurate multiple-Doppler radar wind retrievals require quantification of wind shear below the lowest matched radar scan elevation (often ~100- 300 m AGL even in high-density research deployments). This is a full resolution nexrad doppler radar loop covering the entire national lower 48 states. Although three-dimensional wind retrievals from multiple-Doppler radar observations are a common tool for severe storm analyses, few examples have been presented from cases examined in the Southeastern U.S. The 12 hour Surface Analysis map shows current weather conditions, including frontal and high/low pressure positions, satellite infrared (IR) cloud cover, and areas of precipitation. ![]()
