RISThe Role of Convective Instability in an Oklahoma Squall Line
Publisher: American Meteorological Society
Abstract: Previous investigations of the 8 June 1966 National Severe Storms Laboratory case show that mesoscale lift from an ?inland sea breeze? due to a newly formed temperature gradient preceded convection. Using additional surface ...
Convective Inhibition as a Predictor of Convection during AVE-SESAME II
Publisher: American Meteorological Society
Abstract: The AVE-SESAME 11 data set of 19 April 1979 is examined to determine the thermodynamic conditions prior to the onset of deep convection in western Kansas. The observations indicate that the convective region was characterized ...
A Preliminary Investigation of Temperature Errors in Operational Forecasting Models
Publisher: American Meteorological Society
Abstract: Temperatures taken from model output (FOUS reports) routinely transmitted by the National Centers for Environmental Prediction are tabulated to determine errors during three months in the summer of 1996. These short-term ...
Simulation of the New England Sea Breeze: The Effect of Grid Spacing
Publisher: American Meteorological Society
Abstract: The fifth-generation Pennsylvania State University?National Center for Atmospheric Research (Penn State? NCAR) Mesoscale Model (MM5) was run for seven cases from 2001 in which a sea breeze develops along the eastern New ...
The Spread of Tropical Storm Tracks in Three Versions of NCEP’s Global Ensemble Model: Focus on Hurricane Edouard (2014)
Publisher: American Meteorological Society
Abstract: AbstractSince 2012, the National Centers for Environmental Prediction?s Global Ensemble Forecast System (GEFS) has undergone two major upgrades. Version 11 was introduced in December 2015, with a new dynamic scheme, improved ...
Global Ensemble Forecast Tracks for Tropical Storm Debby
Publisher: American Meteorological Society
Abstract: perational-model track forecasts for Tropical Storm Debby (June 2012) diverged as much as 180°, making the National Hurricane Center forecast particularly challenging. Forecast tracks from the members of the National Centers ...
Forecasts for the Community by Students at the University of Lowell
Publisher: American Meteorological Society
Abstract: Students in the meteorology program at the University of Lowell provide weather forecasts for the university community and for the residents of the Lowell area. The forecasting service is organized and run entirely by the ...
A Mesobeta-Scale Model in Boundary-Layer Coordinates
Publisher: American Meteorological Society
Abstract: A mesobeta-scale numerical model is described that is designed specifically for operational use on relatively small computers (supermicro-class computers of the MicroVAX 3000/4000 type). A major aspect of the model leading ...
Steering Flow Sensitivity in Forecast Models for Hurricane Ian (2022)

Regional and Large-Scale Influences on Summer Ozone Levels in Southern California
Publisher: American Meteorological Society
Abstract: he links between daily ozone levels in Southern California and atmospheric circulation at regional and large scales are examined for July?September 1994?2001. The monitoring station in Pasadena is used as the primary basis ...
