RISOn the Role of Snow Cover in Depressing Air Temperature
Publisher: American Meteorological Society
Abstract: This study empirically examines the role of snow depth on the depression of air temperature after controlling for effect of temperature changes above the boundary layer. In addition, this study examines the role of cloud ...
The Synergistic Relationship between Soil Moisture and the Low-Level Jet and Its Role on the Prestorm Environment in the Southern Great Plains
Publisher: American Meteorological Society
Abstract: Changes in low-level moisture alter the convective parameters [e.g., convective available potential energy (CAPE), lifted index (LI), and convective inhibition (CIN)] as a result of alterations in the latent and sensible ...
Derecho Hazards in the United States
Publisher: American Meteorological Society
Abstract: Convectively generated wind-storms occur over broad temporal and spatial scales; however, the more widespread and longer lived of these windstorms have been given the name ?derecho.? Utilizing an integrated derecho database, ...
Interepochal Changes in Summer Precipitation in the Southeastern United States: Evidence of Possible Urban Effects near Atlanta, Georgia
Publisher: American Meteorological Society
Abstract: Through modification of the planetary boundary layer, urbanization has the potential to have a significant impact on precipitation totals locally. Using daily summer-season precipitation data at 30 stations from 1953 to ...
Estimations of Hazardous Convective Weather in the United States Using Dynamical Downscaling
Publisher: American Meteorological Society
Abstract: igh-resolution (4 km; hourly) regional climate modeling is utilized to resolve March?May hazardous convective weather east of the U.S. Continental Divide for a historical climate period (1980?90). A hazardous convective ...
Patterns and Causes of Atlanta's Urban Heat Island–Initiated Precipitation
Publisher: American Meteorological Society
Abstract: Because of rapid growth and urbanization of Atlanta, Georgia, over the past few decades, the city has developed a pronounced urban heat island (UHI) that has been shown to enhance and possibly to initiate thunderstorms. ...
Standardizing the definition of a “pulse” thunderstorm
Publisher: American Meteorological Society
Abstract: solated, short-lived thunderstorms forming in weakly forced environments are referenced through a surplus of terminology. Further, the language used to describe the strongest, severe-weather-producing subset of these storms ...
Convection Initiation along Soil Moisture Boundaries in the Southern Great Plains
Publisher: American Meteorological Society
Abstract: Boundaries between two dissimilar air masses have been shown to be the focus region for convection initiation. One feature that has been shown to create these boundaries, as well as mesoscale circulation patterns conducive ...
A Climatology of Derecho-Producing Mesoscale Convective Systemsin the Central and Eastern United States, 1986–95. Part I: Temporal and Spatial Distribution
Publisher: American Meteorological Society
Abstract: In 1888, Iowa weather researcher Gustavus Hinrichs gave widespread convectively induced windstorms the name ?derecho?. Refinements to this definition have evolved after numerous investigations of these systems; however, ...
