RISThe Formation of Small-Scale Atmospheric Vortices via Baroclinic Horizontal Shearing Instability
Publisher: American Meteorological Society
Abstract: his study presents a series of idealized simulations that attempt to replicate shear zones typical of drylines and other near-surface boundaries in the presence of horizontal virtual density gradients. The series of dry ...
The Formation of Small-Scale Atmospheric Vortices via Horizontal Shearing Instability
Publisher: American Meteorological Society
Abstract: otivated by high-resolution observations of small-scale atmospheric vortices along near-surface boundaries, this study presents a series of idealized simulations that attempt to replicate shear zones typical of drylines ...
A Multiscale Observational Case Study of the Development of an Isolated High Plains Tornadic Supercell
Publisher: American Meteorological Society
Abstract: On 21 May 1995, a strong tornado developed with an isolated supercell in southwestern Nebraska. Large-scale conditions were not supportive of a tornadic thunderstorm outbreak; however, evidence suggests significant mesoscale ...
A Lagrangian Objective Analysis Technique for Assimilating In Situ Observations with Multiple-Radar-Derived Airflow
Publisher: American Meteorological Society
Abstract: A new Lagrangian analysis technique is developed to assimilate in situ boundary layer measurements using multi-Doppler-derived wind fields, providing output fields of water vapor mixing ratio, potential temperature, and ...
A New Technique to Estimate Sensible Heat Fluxes around Micrometeorological Towers Using Small Unmanned Aircraft Systems
Publisher: American Meteorological Society
Abstract: AbstractUpscaling point measurements from micrometeorological towers is a challenging task that is important for a variety of applications, for example, in process studies of convection initiation, carbon and energy budget ...
Application of Bulk Richardson Parameterizations of Surface Fluxes to Heterogeneous Land Surfaces

The Dryline on 22 May 2002 during IHOP: Ground-Radar and In Situ Data Analyses of the Dryline and Boundary Layer Evolution
Publisher: American Meteorological Society
Abstract: On the afternoon and evening of 22 May 2002, high-resolution observations of the boundary layer (BL) and a dryline were obtained in the eastern Oklahoma and Texas panhandles during the International H2O Project. Using ...
Simulation of Dryline Misovortex Dynamics and Cumulus Formation
Publisher: American Meteorological Society
Abstract: dryline and misocyclones have been simulated in a cloud-resolving model by applying specified initial and time-dependent lateral boundary conditions obtained from analyses of the 22 May 2002 International H2O Project ...
Evaluation of the High-Resolution Rapid Refresh (HRRR) Model Using Near-Surface Meteorological and Flux Observations from Northern Alabama
Publisher: American Meteorological Society
Abstract: AbstractThe High-Resolution Rapid Refresh (HRRR) model became operational at the National Centers for Environmental Prediction (NCEP) in 2014 but the HRRR?s performance over certain regions of the coterminous United States ...
