Forecasting Drought Using the Agricultural Reference Index for Drought (ARID): A Case Study
(American Meteorological Society, 2012)rought forecasting can aid in developing mitigation strategies and minimizing economic losses. Drought may be forecast using a drought index, which is an indicator of drought. The agricultural reference index for drought ... -
A Modified Flood Severity Assessment for Enhanced Decision Support: Application to the Boscastle Flash Flood of 2004
(American Meteorological Society, 2012)modified flash flood severity assessment is presented, based on scoring a set of factors according to their potential for generating extreme catchment-scale flooding. Improvements are made to the index through incorporation ... -
Climatological Characteristics of Fog at Cape Town International Airport
(American Meteorological Society, 2013)he character of fog at Cape Town International Airport (CTIA), South Africa, is investigated, using 13 yr of historical hourly data during the period 1997?2010. Hourly surface observations are used to identify fog types ... -
Hurricane Eyewall Slope as Determined from Airborne Radar Reflectivity Data: Composites and Case Studies
(American Meteorological Society, 2012)nderstanding and predicting the evolution of the tropical cyclone (TC) inner core continues to be a major research focus in tropical meteorology. Eyewall slope and its relationship to intensity and intensity change is one ... -

Use of Multiple Verification Methods to Evaluate Forecasts of Convection from Hot- and Cold-Start Convection-Allowing Models
(American Meteorological Society, 2012)his study uses both traditional and newer verification methods to evaluate two 4-km grid-spacing Weather Research and Forecasting Model (WRF) forecasts: a ?cold start? forecast that uses the 12-km North American Mesoscale ... -
An Intercomparison of UW Cloud-Top Cooling Rates with WSR-88D Radar Data
(American Meteorological Society, 2012)he University of Wisconsin Convective Initiation (UWCI) algorithm utilizes geostationary IR satellite data to compute cloud-top cooling (UW-CTC) rates and assign CI nowcasts to vertically growing clouds. This study is ... -
The Operational Generation of Continuous Winds in the Australian Region and Their Assimilation with 4DVAR
(American Meteorological Society, 2012)tmospheric motion vectors (AMVs) have been generated continuously from Multifunctional Transport Satellite 1 Replacement (MTSAT-1R) radiance data (imagery) since 2005, and more recently from MTSAT-2, which are operated by ... -
Great Salt Lake–Effect Precipitation: Observed Frequency, Characteristics, and Associated Environmental Factors
(American Meteorological Society, 2012)his climatology examines the environmental factors controlling the frequency, occurrence, and morphology of Great Salt Lake?effect (GSLE) precipitation events using cool season (16 September?15 May) Weather Surveillance ... -
Comparison of Mobile-Radar Measurements of Tornado Intensity with Corresponding WSR-88D Measurements
(American Meteorological Society, 2012)n the United States, visual observations of tornadoes and/or the existence of tornado damage currently provide the sole evidence of tornadogenesis in association with a mesocyclone or other radar-detected storm-scale vortex. ... -
Climatology and Meteorological Evolution of Major Wildfire Events over the Northeast United States
(American Meteorological Society, 2012)his study presents a spatial and temporal climatology of major wildfire events, defined as >100 acres burned (>40.47 ha, where 1 ha = 2.47 acre), in the northeast United States from 1999 to 2009 and the meteorological ... -
Research Radar Analyses of the Internal Boundary Layer over Cape Canaveral, Florida, during the Landfall of Hurricane Frances (2004)
(American Meteorological Society, 2012)he structure of the coastal internal boundary layer (IBL) during a landfalling hurricane has important ramifications on operational forecasting, structural design, and poststorm damage assessment. Despite these important ... -
