Comparison of Evaporation and Cold Pool Development between Single-Moment and Multimoment Bulk Microphysics Schemes in Idealized Simulations of Tornadic Thunderstorms
TL;DR: In this article, a multimoment bulk microphysics parameterization scheme capable of predicting up to three moments of the particle or drop size distribution (DSD) for several liquid and ice hydrometeor species is evaluated and compared with traditional single-moment schemes.
Journal ArticleDOI

TL;DR: In this paper, the authors explored the ability of short-range convective-scale ensemble forecasts to provide guidance that could be used in warning operations for five events: two tornadic supercell thunderstorms, a macroburst, a damaging windstorm and a flash flood.
Journal ArticleDOI
Low-Level ZDR Signatures in Supercell Forward Flanks: The Role of Size Sorting and Melting of Hail
Daniel T. Dawson,Edward R. Mansell,Youngsun Jung,Louis J. Wicker,Matthew R. Kumjian,Ming Xue +5 more
TL;DR: In this article, the authors used a multimoment bulk micro-physics scheme, in which size sorting is allowed or disallowed for hydrometeor species, in the presence of vertical wind shear.
Journal ArticleDOI
Impact of the Environmental Low-Level Wind Profile on Ensemble Forecasts of the 4 May 2007 Greensburg, Kansas, Tornadic Storm and Associated Mesocyclones
TL;DR: In this paper, the early tornadic phase of the Greensburg, Kansas supercell on the evening of 4 May 2007 is simulated using a set of storm-scale (1-km horizontal grid spacing) 30-member ensemble Kalman filter (EnKF) data assimilation and forecast experiments.
Journal ArticleDOI
Diagnosing the Intercept Parameter for Exponential Raindrop Size Distribution Based on Video Disdrometer Observations: Model Development
TL;DR: In this paper, a diagnostic relation of N0 as a function of rainwater content W is derived based on two-dimensional video disdrometer (2DVD) measurements, which reveals a clear correlation between N0 and W in which N0 increases as W increases.
