RISPredictability and Dynamics of Warm-Core Mesoscale Vortex Formation with the 8 May 2009 “Super Derecho” Event
Publisher: American Meteorological Society
Abstract: he predictability and dynamics of the warm-core mesovortex associated with the northern flank of the 8 May 2009 ?super derecho? event are examined by coupling the Advanced Research Weather Research and Forecasting Model ...
Analysis of the Wind Field Evolution Associated with the Extratropical Transition of Bonnie (1998)
Publisher: American Meteorological Society
Abstract: Extratropical transition brings about a number of environmentally induced structural changes within a transitioning tropical cyclone. Of particular interest among these changes is the acceleration of the wind field away ...
A Climatology of Indirect Tropical Cyclone Interactions in the North Atlantic and Western North Pacific Basins
Publisher: American Meteorological Society
A Climatology of Extreme South American Andean Cold Surges
Publisher: American Meteorological Society
Abstract: AbstractCold surges represent one of several phenomena by which midlatitude features can modulate the atmosphere, both dynamically and thermodynamically, deep into the tropics. This study involves the construction of a ...
The 8 May 2009 Superderecho: Analysis of a Real-Time Explicit Convective Forecast
Publisher: American Meteorological Society
Abstract: erein, an analysis of a 3-km explicit convective simulation of an unusually intense bow echo and associated mesoscale vortex that were responsible for producing an extensive swath of high winds across Kansas, southern ...
Development of an Intense, Warm-Core Mesoscale Vortex Associated with the 8 May 2009 “Super Derecho” Convective Event
Publisher: American Meteorological Society
Abstract: n this study, the dynamical processes contributing to warm-core meso-?-scale vortex formation associated with the 8 May 2009 ?super derecho? are examined utilizing two complementary quasi-Lagrangian approaches?a circulation ...
Synoptic Composites of the Extratropical Transition Life Cycle of North Atlantic Tropical Cyclones: Factors Determining Posttransition Evolution
Publisher: American Meteorological Society
Abstract: A 34-member ensemble-mean trajectory through the cyclone phase space (CPS) is calculated using Navy Operational Global Atmospheric Prediction System (NOGAPS) analyses for North Atlantic tropical cyclones (TCs) undergoing ...
Sensitivity in the Overland Reintensification of Tropical Cyclone Erin (2007) to Near-Surface Soil Moisture Characteristics
Publisher: American Meteorological Society
Abstract: his study investigates the impact of abnormally moist soil conditions across the southern Great Plains upon the overland reintensification of North Atlantic Tropical Cyclone Erin (2007). This is tested by analyzing the ...
How Do Forecasters Utilize Output from a Convection-Permitting Ensemble Forecast System? Case Study of a High-Impact Precipitation Event
Publisher: American Meteorological Society
Abstract: he proliferation of ensemble forecast system output in recent years motivates this investigation into how operational forecasters utilize convection-permitting ensemble forecast system guidance in the forecast preparation ...
Assessing the Predictability of Convection Initiation in the High Plains Using an Object-Based Approach
Publisher: American Meteorological Society
Abstract: his study investigates the short-range (0?12 h) predictability of convection initiation (CI) using the Advanced Research Weather Research and Forecasting (WRF) Model (ARW) with a horizontal grid spacing of 429 m. A unique ...
