FOUR-DIMENSIONAL ENSEMBLE KALMAN FILTER ASSIMILATION OF HIGH TEMPORAL RESOLUTION PHASED ARRAY RADAR DATA WITH REAL CONVECTIVE STORM CASES
(2020-05)With the US National Weather Service (NWS) Weather Surveillance Radar-1988 Doppler (WSR-88D) radar network aging, a candidate for replacing it is phased array radar (PAR). The defining feature of PAR is an electronically ... -
Improving High-Resolution Tropical Cyclone Prediction using a Cycled, GSI-Based Hybrid Ensemble-Variational Data Assimilation System for HWRF with Vortex Scale Observations
(2019-12-13)A Gridpoint Statistical Interpolation analysis system (GSI)-based, continuously cycled, dual-resolution hybrid ensemble-variational (EnVar) data assimilation (DA) system is developed for the Hurricane Weather Research and ... -
Improving short-term forecast of severe and high-impact weather events using a weather-dependent hybrid ensemble-variational data assimilation system with radar and satellite derived observations
(2023-05-12)A hybrid ensemble-variational (EnVAR) data assimilation and forecast system, namely WoF-Hybrid, was initially developed at the National Severe Storms Laboratory (NSSL) supported by the NOAA Warn-on-Forecast project (WoF). ... -
Tropospheric Polar Vortices and Impacts on Atmospheric Flow from the Arctic to the Mid-Latitudes using a New Global Modeling System
(2020-05-08)The observed rapid changes in the Arctic are important to quantify not only for understanding the region, but also for understanding how processes between the Arctic and lower latitudes can interact to culminate in high-impact ...
