RISObservations of Urban Heat Island Influence on Lake-Breeze Frontal Movement
Publisher: American Meteorological Society
Abstract: redictions of lake and sea breezes are particularly important in large coastal population centers because of the circulations? influence on heat-wave relief, energy use, precipitation, and dispersion of pollutants. While ...
Sounding Characteristics that Yield Significant Convective Inhibition Errors due to Ascent Rate and Sensor Response of In Situ Profiling Systems
Publisher: American Meteorological Society
Abstract: Accurate measurements of the convective inhibition (CIN) associated with capping inversions are critical to forecasts of deep convection initiation. The goal of this work is to determine the sounding characteristics most ...
The Impact of Sensor Response and Airspeed on the Representation of the Convective Boundary Layer and Airmass Boundaries by Small Unmanned Aircraft Systems
Publisher: American Meteorological Society
Abstract: AbstractThe objective of the research presented is to assess the impact of sensor response and aircraft airspeed on the accuracy of in situ observations collected by small unmanned aircraft systems profiling the convective ...
Lake-Effect Thunderstorms in the Lower Great Lakes
Publisher: American Meteorological Society
Abstract: Cloud-to-ground (CG) lightning, radar, and radiosonde data were examined to determine how frequently lake-effect storms (rain/snow) with lightning occurred over and near the lower Great Lakes region (Lakes Erie and Ontario) ...
Elevated Potential Instability in the Comma Head: Distribution and Development
Publisher: American Meteorological Society
Abstract: AbstractThe development of elevated potential instability within the comma head of a continental winter cyclone over the north-central United States is examined using a 63-h Weather Research and Forecasting (WRF) Model ...
Dynamics of Cloud-Top Generating Cells in Winter Cyclones. Part II: Radiative and Instability Forcing
Publisher: American Meteorological Society
Abstract: ecent field observations suggest that cloud-top precipitation generating cells (GCs) are ubiquitous in the warm-frontal and comma-head regions of midlatitude winter cyclones. The presence of fallstreaks emanating from the ...
Dynamics of Cloud-Top Generating Cells in Winter Cyclones. Part I: Idealized Simulations in the Context of Field Observations
Publisher: American Meteorological Society
Abstract: his paper assesses the influence of radiative forcing and latent heating on the development and maintenance of cloud-top generating cells (GCs) in high-resolution idealized Weather Research and Forecasting Model simulations ...
Dynamics of Cloud-Top Generating Cells in Winter Cyclones. Part III: Shear and Convective Organization
Publisher: American Meteorological Society
Abstract: AbstractCloud-top generating cells (GCs) are a common feature atop stratiform clouds within the comma head of winter cyclones. The dynamics of cloud-top GCs are investigated using very high-resolution idealized WRF Model ...
The Role of Cloud-Top Generating Cells and Boundary Layer Circulations in the Finescale Radar Structure of a Winter Cyclone over the Great Lakes
Publisher: American Meteorological Society
Abstract: ata from airborne W-band radar are used in conjunction with thermodynamic fields from the Weather Research and Forecasting Model and air-parcel back trajectories from the HYSPLIT model to investigate the finescale reflectivity, ...
Finescale Radar and Airmass Structure of the Comma Head of a Continental Winter Cyclone: The Role of Three Airstreams
Publisher: American Meteorological Society
Abstract: ata from airborne W-band radar, thermodynamic fields from the Weather Research and Forecasting (WRF) Model, and air parcel back trajectories from the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model ...
