Verification of 10-Meter Wind Forecasts from NSSL-WRF in Predicting Severe Wind-Producing MCSs
(2016-12-16)
Predicting convective winds associated with mesoscale convective systems (MCSs) remains a major challenge for operational severe weather forecasters. To assess the performance of the Weather Research and Forecasting Model ...
A Two Part Study in the Evaluation of Quantitative Precipitation Forecasts from Convection-Allowing Models
(2017-12)
Previous studies examining convection-allowing models (CAMs), as well as NOAA/Hazardous Weather Testbed Spring Forecasting Experiments (SFEs) have typically emphasized “day 1” (12-36 h) forecast guidance. These studies ...
Kinematics, Thermodynamics, and Microphysics of the 25-26 June 2015 Kansas MCS during PECAN
(2018-05)
This case study analyzes a nocturnal mesoscale convective system (MCS) that was observed in northeast Kansas as part of the Plains Elevated Convection at Night (PECAN) field experiment on 25-26 June 2015. Over the course ...
Characteristics of Tropopause Polar Vortices Based on Observations Over The Greenland Ice Sheet
(2018-12-14)
Tropopause Polar Vortices (TPVs) are long-lived, coherent vortices that are identified by closed material contours of potential temperature on the dynamic tropopause. They are characterized by PV anomalies that spend most ...
Understanding and Predicting Nocturnal Convection Initiation using an Ensemble-based Multi-scale Data Assimilation System
(2016-08-12)
A nocturnal maximum in precipitation exists over the Great Plains during the summer. The initiation of nocturnal storms is notoriously difficult to forecast in numerical models due to the storms often involving interactions ...
