Assimilation of ZDR Columns for Improving the Spin-Up and Forecast of Convection in Storm-Scale Models Achieving accurate storm-scale analyses and reducing the spin-up time of modeled convection is a primary motivation for assimilating radar data and an active area of research. One popular technique for accomplishing this is diabatic initialization, in which latent heat and/or […]

SENSITIVITY OF ENSEMBLE FORECASTS OF SUPERCELLS TO INITIAL CONDITION UNCERTAINTY   The sensitivity of full-physics ensemble forecasts of supercells to initial condition (IC) uncertainty is investigated. The motivation for the study largely stems from the NOAA Warn-on-Forecast (WoF) program, where the primary objective is to develop a storm-scale ensemble prediction system that will generate probabilistic […]

Forecaster Cognitive Workload With increasing amounts of data becoming available to forecasters, the question of how rapidly-updating phased array radar data will affect forecasters’ cognitive workload is of interest. In this seminar, an overview of cognitive workload will be given, including examples of the types of methods and tools that can be used to measure […]

Microphysical Treatment of Hail in High-Resolution Supercell Simulations   Hail causes over $1.0 billion in damage annually in the United States, despite this explicit hail prediction remains a relatively understudied subject.  This study compares high-resolution (500 m horizontal grid spacing) hail simulations for a severe hail event that impacted central Oklahoma on 19 May 2013.  […]

Impact of Aircraft Observations on Hurricane Prediction using a Regional OSSE Framework   Aircraft reconnaissance missions remain the only means of collecting direct measurements of marine atmospheric conditions affecting tropical cyclone (TC) formation and evolution. These airborne measurements are crucial in both the operational forecasting of TCs and the understanding of the mechanisms that drive […]

Storm-Scale Downdraft Evolution in a High-Precipitation Supercell Thunderstorm

Numerous observational studies have shown that the strength and position of the rear-flank downdraft (RFD) in supercell thunderstorms can vary substantially during the mesocyclone life cycle.
