Integrated Wind and Thermodynamic Profiling for High-Impact Nowcasting

Continuous boundary layer wind and thermodynamic profiles from regional networks are widely acknowledged as essential for accurate high-impact weather modeling and forecasting[1]. Single-site integrated profiles became available more than a decade ago[2] and networks are now proliferating[3]. Integrated profiles can be ingested in radiosonde analysis and display software, providing continuously updated Forecast Indices and Tools. The profiles can also be assimilated in numerical weather models. We present integrated thermodynamic (radiometer) and wind (radar, lidar, sodar) profiles combined with numerical weather models via variational analysis[4], and discuss resulting high impact Nowcasting case studies.
