RISEnvironmental Conditions Associated with the Dallas Microburst Storm Determined from Satellite Soundings
Publisher: American Meteorological Society
Abstract: The thermodynamic structure of the troposphere in the vicinity of the microburst storm at Dallas-Ft. Worth Airport (DFW), Texas on 2 August 1985 is described. The analysis was based principally on a set of vertical soundings ...
Advances in the Detection and Analysis of Fog at Night Using GOES Multispectral Infrared Imagery
Publisher: American Meteorological Society
Abstract: A technique is described for the detection of fog and low clouds at night using multispectral infrared (IR) imagery from Geostationary Operational Environmental Satellites (GOES). The technique requires subtraction and ...
Detection of Important Atmospheric and Surface Features by Employing Principal Component Image Transformation of GOES Imagery
Publisher: American Meteorological Society
Abstract: The detection of dust, fire hot spots, and smoke from the Geostationary Operational Environmental Satellite (GOES) is made easier by employing the principal component image (PCI) technique. PCIs are created by an eigenvector ...
Assessment of Aircraft Icing Potential and Maximum Icing Altitude from Geostationary Meteorological Satellite Data
Publisher: American Meteorological Society
Abstract: A satellite product that displays regions of aircraft icing potential, along with corresponding cloud-top heights, has been developed using data from the Geostationary Operational Environmental Satellite (GOES) imager and ...
An Objective Clear-Air Turbulence Forecasting Technique: Verification and Operational Use
Publisher: American Meteorological Society
Abstract: An objective technique for forecasting clear-air turbulence (CAT) is described. An index is calculated based on the product of horizontal deformation and vertical wind shear derived from numerical model forecast winds ...
Recent Improvements to the GOES Microburst Products
Publisher: American Meteorological Society
Abstract: The downburst is defined as a strong downdraft produced by a deep convective storm that induces strong or damaging winds on or near the earth's surface. Because of the intense wind shear they produce, downbursts are a ...
Improvements to an Operational Clear-Air Turbulence Diagnostic Index by Addition of a Divergence Trend Term
Publisher: American Meteorological Society
Abstract: An operational clear-air turbulence (CAT) diagnostic index has been modified to improve its performance. The Ellrod?Knapp turbulence index (TI) was developed in the early 1990s and is in use at many aviation forecasting ...
Structure and Interaction in the Subcloud Region of Thunderstorms
Publisher: American Meteorological Society
Abstract: The subcloud inflow and outflow structures of two multicell thunderstorms were synthesized from data by a variety of observation systems. The systems included digitized radar, instrumented aircraft, radar chaff, rawinsondes ...
An Evaluation of the Efficacy of Using Observed Lightning to Improve Convective Lightning Forecasts
Publisher: American Meteorological Society
Abstract: ynamic lightning forecasts [total and cloud to ground (CG)] were produced on a convection-allowing forecast grid with 4-km grid spacing with lightning assimilation (ASML) and without lightning assimilation [control (CNTL)]. ...
A Multiple-Case Analysis of Nocturnal Radiation-Fog Development in the Central Valley of California Utilizing the GOES Nighttime Fog Product
Publisher: American Meteorological Society
Abstract: Radiation fog in the Central Valley of California has received very little attention in terms of climatological research. This study uses the Geostationary Operational Environmental Satellite (GOES) nighttime fog product ...
