Gregory Jennrich-March 6-Weather and Climate Systems Seminar
In the United States and throughout the world, extreme precipitation events are a major cause of loss in life, property, and economic progress. Although the science of hydrometeorology has made significant improvements to the prediction and understanding of these events in recent decades, there is still much to learn about these events in the subseasonal to seasonal (S2S) timescale.

Day-ahead (20 - 22 hour) 3-km grid spacing convection-allowing model forecasts are performed for a severe hail event on 8 May 2017 using six different multi-moment microphysics (MP) schemes including: the Milbrandt and Yau double-moment (MY2), Thompson (THO), NSSL double-moment (NSSL), Morrison double-moment graupel (MOR-G) and hail (MOR-H), and Predicted Particle Properties (P3) schemes.

In a previous study, Chen and Snyder (2007) showed that a large location error in the background forecast can result in a poor performance of ensemble Kalman filter (EnKF) data assimilation (DA) due to the violation of the Gaussian assumptions. One way to alleviate this issue is to apply vortex relocation (VR) before the ensemble-based DA.

Abstract: The maximum upward vertical velocity at the leading edge of a density current is commonly between 8-10 m/s. However, while the propagation speed and depth of a density current have been the subject of past studies, research describing the vertical velocity at the leading edge of a density current is relatively limited.
