Meteorological Analysis for the Las Vegas, Nevada, Flood of 3 July 1975
Publisher: American Meteorological Society
Abstract: Meteorological data are analysed to determine the location and intensity of the rainstorms that led to flash flooding in the Las Vegas Valley and resulted in approximately $4.5 million in damages on 3 July 1975. The effective ...
Temporal Changes in Horizontal Diffusion Parameters of a Single Nuclear Debris Cloud
Publisher: American Meteorological Society
Abstract: An evaluation is made of the variations of σy and KH over a 70-hr period as derived from analyses of radiological and meteorological data collected during extensive aerial sampling of a single nuclear debris cloud. These ...
Determining the Relative Frequency of Occurrence of Local Cumulonimbus Activity through Discriminant Analysis
Publisher: American Meteorological Society
Abstract: Discriminant analysis is used to develop a cumulonimbus prediction equation (Z index) for a single station during the period June through September. Based on dependent data, the Z index explains 43% of the variance, while ...
Spatial Variability of Warm Season Echo Activity as a Function of Two Stability Indices Computed from the Yucca Flat, Nevada, Rawinsonde
Publisher: American Meteorological Society
Abstract: A radar echo survey for two warm seasons is used to determine the spatial variability of the relative frequency of occurrence of an echo day in six selected areas. These areas include the Las Vegas Valley, Lake Mead and ...
Overview of Regional-Scale Numerical Models
Publisher: American Meteorological Society
Abstract: The general concept of a regional scale developed from the application of atmospheric pollution models to predict or diagnose air quality over air sheds. The regional scale is proposed to be the ?- and α-mesoscale subrange, ...
Verification of Some Numerical Models for Operationally Predicting Mesoscale Winds Aloft
Publisher: American Meteorological Society
Abstract: Four numerical models are described for predicting mesoscale winds aloft for a 6 h period. These models are all tested statistically against persistence as the control forecast and against predictions made by operational ...
Photogrammetric and Photometric Investigation of a Smoke Plume Viewed from Space
Publisher: American Meteorological Society
Abstract: Detailed analyses of an Apollo 6 stereographic photograph of a smoke plume which originated in southern Arizona and crossed over into Mexico are presented to illustrate how high-resolution photography can aid meteorologists ...
