RISThe Birth and Early Years of the Storm Prediction Center
Publisher: American Meteorological Society
Abstract: An overview of the birth and development of the National Weather Service?s Storm Prediction Center, formerly known as the National Severe Storms Forecast Center, is presented. While the center?s immediate history dates to ...
Cold Pools and MCS Propagation: Forecasting the Motion of Downwind-Developing MCSs
Publisher: American Meteorological Society
Abstract: The primary factors that affect the direction of propagation and overall movement of surface-based mesoscale convective systems (MCSs) are discussed. It is shown that although propagation is indeed related to the strength ...
The Meteorological Operations Division of the National Meteorological Center
Publisher: American Meteorological Society
Abstract: The Meteorological Operations Division of the National Meteorological Center is the primary analysis and forecast facility of the National Weather Service. The division's many products provide guidance to the meteorological ...
Elevated Convection and Castellanus: Ambiguities, Significance, and Questions
Publisher: American Meteorological Society
Abstract: The term elevated convection is used to describe convection where the constituent air parcels originate from a layer above the planetary boundary layer. Because elevated convection can produce severe hail, damaging surface ...
Views on Applying RKW Theory: An Illustration Using the 8 May 2009 Derecho-Producing Convective System
Publisher: American Meteorological Society
Abstract: his work presents an analysis of the vertical wind shear during the early stages of the remarkable 8 May 2009 central U.S. derecho-producing convective system. Comments on applying Rotunno?Klemp?Weisman (RKW) theory to ...
A Proposed Revision to the Definition of “Derecho”
Publisher: American Meteorological Society
Abstract: he word ?derecho? was first used by Gustavus Hinrichs in 1888 to distinguish the widespread damaging windstorms that occurred on occasion over the mid?Mississippi Valley region of the United States from damaging winds ...
Easing Into Norman: Ed Kessler on the Origins and Growth of the National Severe Storms Laboratory
Publisher: American Meteorological Society
Abstract: wing essay is excerpted from conversations with Edwin Kessler, founding director of NOAA's National Severe Storms Laboratory in Norman, Oklahoma, conducted by Ariel Cohen and Stephen and Sarah Corfidi of the National Weather ...
A Preliminary Study of Severe Wind-Producing MCSs in Environments of Limited Moisture
Publisher: American Meteorological Society
Abstract: An examination of severe wind-producing mesoscale convective systems that occur in environments of very limited moisture is presented. Such systems, herein referred to as low-dewpoint derechos (LDDs), are difficult to ...
Forecasting the Maintenance of Quasi-Linear Mesoscale Convective Systems
Publisher: American Meteorological Society
Abstract: The problem of forecasting the maintenance of mesoscale convective systems (MCSs) is investigated through an examination of observed proximity soundings. Furthermore, environmental variables that are statistically different ...
