The 2000 Fire Season: Lightning-Caused Fires
(American Meteorological Society, 2002)A large number of lightning-caused fires burned across the western United States during the summer of 2000. In a previous study, the authors determined that a simple index of low-level moisture (85-kPa dewpoint depression) ... -
The Influence of Seasonally Varying Atmospheric Characteristics on the Intensity of Nocturnal Cooling in a High Mountain Hollow
(American Meteorological Society, 2002)Seasonal differences in the longwave radiation balance, diurnal cycles of humidity and cloudiness, and ambient winds during the warm season were evaluated to determine their effect on the nocturnal cooling processes of a ... -
Evaluating the Adequacy of Simulating Maximum and Minimum Daily Air Temperature with the Normal Distribution
(American Meteorological Society, 2002)Weather simulation models are commonly used to generate synthetic daily weather for use in studies of crop growth, water quality, water availability, soil erosion, climate change, and so on. Synthetic weather sequences are ... -
Stochastic Modeling of Hurricane Damage
(American Meteorological Society, 2002)A compound Poisson process is proposed as a stochastic model for the total economic damage associated with hurricanes. This model consists of two components, one governing the occurrence of events and another specifying ... -
Rainfall Modification by Major Urban Areas: Observations from Spaceborne Rain Radar on the TRMM Satellite
(American Meteorological Society, 2002)Data from the Tropical Rainfall Measuring Mission (TRMM) satellite's precipitation radar (PR) were employed to identify warm-season rainfall (1998?2000) patterns around Atlanta, Georgia; Montgomery, Alabama; Nashville, ... -
Experiments in Rainfall Estimation with a Polarimetric Radar in a Subtropical Environment
(American Meteorological Society, 2002)A unique dataset consisting of high-resolution polarimetric radar measurements and dense rain gauge and disdrometer observations collected in east-central Florida during the summer of 1998 was examined. Comparison of the ... -
Large-Eddy Simulation of Flow and Scalar Transport in a Modeled Street Canyon
(American Meteorological Society, 2002)This study uses large-eddy simulation (LES) to illustrate the flow and turbulence structure and to investigate the mechanism of passive scalar transport in a street canyon. Calculations for a modeled street canyon with ... -
Quality Control for USDA NRCS SM–ST Network Soil Temperatures: A Method and a Dataset
(American Meteorological Society, 2002)In 1991, the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) established its Soil Moisture?Soil Temperature (SM?ST) Pilot Network consisting of 21 stations in 19 states in the contiguous ... -

Cirrus Cloud Ice Water Content Radar Algorithm Evaluation Using an Explicit Cloud Microphysical Model
(American Meteorological Society, 2002)A series of cirrus cloud simulations performed using a model with explicit cloud microphysics is applied to testing ice water content retrieval algorithms based on millimeter-wave radar reflectivity measurements. The ... -
Observation-Time-Dependent Biases and Departures for Daily Minimum and Maximum Air Temperatures
(American Meteorological Society, 2002)Non-calendar-day observations of 24-h minimum and maximum air temperatures can be considerably different from calendar-day or midnight observations. This paper examines the influence of time-of-observation on 24-h temperature ... -
Forecasting Warm-Season Burnoff of Low Clouds at the San Francisco International Airport Using Linear Regression and a Neural Network
(American Meteorological Society, 2002)In this study, both linear regression and a nonlinear neural network are used to forecast burnoff of low clouds in the warm season at San Francisco International Airport (SFO). Both forecast systems show skill scores between ... -
Accuracy of Point and Line Measures of Boundary Layer Cloud Amount
(American Meteorological Society, 2002)Many authors have used upward-looking instruments, such as a laser ceilometer, to estimate the cover of fair-weather cumuli, but little has been mentioned as to the accuracy of these measurements. Results are presented, ... -
Maximum Urban Heat Island Intensity in Seoul
(American Meteorological Society, 2002)The maximum urban heat island (UHI) intensity in Seoul, Korea, is investigated using data measured at two meteorological observatories (an urban site and a rural site) during the period of 1973?96. The average maximum UHI ... -
Mesobeta Profiles to Extrapolate Radar Precipitation Measurements above the Alps to the Ground Level
(American Meteorological Society, 2002)In the Alps, the volume visible by a radar is reduced because of ground clutter, elevated horizon, and earth curvature. This often inhibits a direct view on precipitation close to the ground. When using radar measurements ... -
Lidar Investigation of the Temporal and Spatial Distribution of Atmospheric Aerosols in Mountain Valleys
(American Meteorological Society, 2002)Lidar experiments were conducted in the mountainous region of Bulgaria to determine the spatial and temporal distribution of major aerosol sources and the zones of aerosol accumulation. When these lidar data are combined ... -
Uncertainty Analysis of the TRMM Ground-Validation Radar-Rainfall Products: Application to the TEFLUN-B Field Campaign
(American Meteorological Society, 2002)Efforts to validate the Tropical Rainfall Measuring Mission (TRMM) space-based rainfall products have encountered many difficulties and challenges. Of particular concern is the quality of the ground-based radar products?the ... -
Wind and Turbulence in a Sparse but Regular Plant Canopy
(American Meteorological Society, 2002)Wind velocity statistics from several points within a regular but sparse array of clumped corn plants are analyzed, with each clump consisting of 12 plants, having a mean height of 1.6 m and a collective leaf area of about ... -
Application of Neural Networks to the Simulation of the Heat Island over Athens, Greece, Using Synoptic Types as a Predictor
(American Meteorological Society, 2002)The effect of the synoptic-scale atmospheric circulation on the urban heat island phenomenon over Athens, Greece, was investigated and quantified for a period of 2 yr, employing a neural network approach. A neural network ... -
Confidence Regions and Pooling—Some Statistics for Weather Experimentation
(American Meteorological Society, 2002)The use of confidence intervals for assessing the results of weather modification experiments is demonstrated and is shown to be more informative than tests of significance. Multivariate tests, confidence regions, and ...
