RISAn Algorithm for Detecting the Chesapeake Bay Breeze from Mesoscale NWP Model Output
Publisher: American Meteorological Society
Pressure Transients within MCS Mesohighs and Wake Lows
Publisher: American Meteorological Society
Abstract: By animating enhanced coarse surface pressure observations of 12 1985 Preliminary Regional Experiment for Storm-Scale Operational Research Meteorology (PRE-STORM) mesoscale convective systems (MCSs) the authors exposed 92 ...
Do Meteorologists Suppress Thunderstorms?: Radar-Derived Statistics and the Behavior of Moist Convection
Publisher: American Meteorological Society
Abstract: Meteorologists and other weather enthusiasts sometimes lament that they live in weather holes?places that receive less exciting weather than do their surroundings. This belief seems to stem from countless hours spent gazing ...
The Kinematics of a Midlatitude, Continental Mesoscale Convective System and Its Mesoscale Vortex
Publisher: American Meteorological Society
Abstract: The authors present a unique, scale-discriminating study of the environment-relative circulations within a mesoscale convective system (MCS) and mesoscale convective vortex (MCV). The MCS, a leading convective line and ...
Some Effects of Model Resolution on Simulated Gravity Waves Generated by Deep, Mesoscale Convection
Publisher: American Meteorological Society
Abstract: Over the past decade, numerous numerical modeling studies have shown that deep convective clouds can produce gravity waves that induce a significant vertical flux of horizontal momentum. Such studies used models with ...
Using Temporal Modes of Rainfall to Evaluate the Performance of a Numerical Weather Prediction Model
Publisher: American Meteorological Society
Abstract: The authors demonstrate that much can be learned about the performance of a numerical weather prediction (NWP) model by examining the temporal modes of its simulated rainfall. Observations from the Weather Surveillance ...
A Multimodel Assessment of RKW Theory’s Relevance to Squall-Line Characteristics
Publisher: American Meteorological Society
Abstract: The authors evaluate whether the structure and intensity of simulated squall lines can be explained by ?RKW theory,? which most specifically addresses how density currents evolve in sheared environments. In contrast to ...
Explicit Numerical Diffusion in the WRF Model
Publisher: American Meteorological Society
Abstract: Diffusion that is implicit in the odd-ordered advection schemes in early versions of the Advanced Research core of the Weather Research and Forecasting (WRF) model is sometimes insufficient to remove noise from kinematical ...
Techniques for Using MODIS Data to Remotely Sense Lake Water Surface Temperatures
Publisher: American Meteorological Society
Abstract: his study describes a stepwise methodology used to provide daily high-spatial-resolution water surface temperatures from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite data for use nearly in real time for ...
Temporal Changes in Wind as Objects for Evaluating Mesoscale Numerical Weather Prediction
Publisher: American Meteorological Society
Abstract: The study describes a method of evaluating numerical weather prediction models by comparing the characteristics of temporal changes in simulated and observed 10-m (AGL) winds. The method is demonstrated on a 1-yr collection ...
