MCS Rainfall Forecast Accuracy as a Function of Large-Scale Forcing
Publisher: American Meteorological Society
Abstract: The large-scale forcing associated with 20 mesoscale convective system (MCS) events has been evaluated to determine how the magnitude of that forcing influences the rainfall forecasts made with a 10-km grid spacing version ...
Diagnosis and Optimization of Ensemble Forecasts
Publisher: American Meteorological Society
Abstract: In the current study, a technique that offers a way to evaluate ensemble forecast uncertainties produced either by initial conditions or different model versions, or both, is presented. The technique consists of first ...
The 4 June 1999 Derecho Event: A Particularly Difficult Challenge for Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: Warm season convective system rainfall forecasts remain a particularly difficult forecast challenge. For these events, it is possible that ensemble forecasts would provide helpful information unavailable in a single ...
Influence of Initial Conditions on the WRF–ARW Model QPF Response to Physical Parameterization Changes
Publisher: American Meteorological Society
Abstract: To assist in optimizing a mixed-physics ensemble for warm season mesoscale convective system rainfall forecasting, the impact of various physical schemes as well as their interactions on rainfall when different initializations ...
The Impact of Different Physical Parameterizations and Their Interactions on Cold Season QPF in the American River Basin
Publisher: American Meteorological Society
Abstract: The most significant precipitation events in California occur during the winter and are often related to synoptic-scale storms from the Pacific Ocean. Because of the terrain characteristics and the fact that the urban and ...
Evaluation and Comparison of Microphysical Algorithms in ARW-WRF Model Simulations of Atmospheric River Events Affecting the California Coast
Publisher: American Meteorological Society
Abstract: Numerical prediction of precipitation associated with five cool-season atmospheric river events in northern California was analyzed and compared to observations. The model simulations were performed by using the Advanced ...
The Impact of Different WRF Model Physical Parameterizations and Their Interactions on Warm Season MCS Rainfall
Publisher: American Meteorological Society
Abstract: In recent years, a mixed-physics ensemble approach has been investigated as a method to better predict mesoscale convective system (MCS) rainfall. For both mixed-physics ensemble design and interpretation, knowledge of the ...
An Evaluation of NOAA Modeled and In Situ Soil Moisture Values and Variability across the Continental United States
Publisher: American Meteorological Society
An Adaptive Approach for the Calculation of Ensemble Gridpoint Probabilities
Publisher: American Meteorological Society
Abstract: AbstractTraditional ensemble probabilities are computed based on the number of members that exceed a threshold at a given point divided by the total number of members. This approach has been employed for many years in ...
