Josh Gebauer- May 3- Convective Meteorology Seminar

Name:     Joshua Gebauer Title:    Evaluating the Impact of Rapid-Scan Radar Data on Dual-Doppler Vertical Velocity Retrievals Location: NWC 5600 Date:     05/03/2019 Time:     3:00 PM Series:   Convective Meteorology (Mesoscale Dynamics) Abstract: Vertical velocity is the most difficult wind component to retrieve from dual-Doppler analysis, as radial velocities typically poorly capture the vertical component of the wind. Prior […]

Bo Huang-April 19- Convective Meteorology Seminar

Abstract: A uniform spatial localization for all scales is commonly applied in the ensemble-based data assimilation (DA) systems to treat sampling errors. Early studies suggest that the optimal effective localization length for the large scale is broader than that for the small scale.

Andrew Mahre- April 19- Convective Meteorology Seminar

With NEXRAD now approaching the 30-year mark since its installation, intense study has been underway on designing a replacement national weather radar system. One system design framework—a multifunction phased array radar (MPAR) system—is designed to meet the needs of several end users simultaneously, including NOAA, FAA, DoD, and DHS. More recently, a weather-only radar system with update times on the order of one minute has been investigated.
