Summary of METROMEX, Volume 1: Weather Anomalies and Impacts

This is the first of two volumes presenting the major findings from the 1971-1975 METROMEX field operations at St. Louis. It focuses on final interpretations and conclusions obtained primarily through climatological-statistical analyses of spatial and temporal distributions of surface precipitations and severe storms. It addresses also the impacts related to the urban-produced precipitation anomalies. Volume 2 concerns the causes of the anomalies

Summary of METROMEX, Volume 2: Causes of Precipitation Anomalies

This is the last of two volumes presenting the major findings from the 1971-1975METROMEX field operations at St. Louis. It presents climatological analyses of surface weather conditions, but primarily concerns those factors helping to describe the causes of the anomalies. Volume 1 covers spatial and temporal distributions of surface precipitation and severe storms, and impacts of urban-produced precipitation anomalies. Volume 2 describes relevant surface weather conditions including temperature, moisture, and winds, all influenced by the urban area. Urban influences extend well into the boundary layer affecting aerosol distributions, winds, and the thermodynamic structure, and often reach cloud base levels. Studies of modification of cloud and rain processes show urban-industrial influences on 1) initiation, local distribution, and characteristics of summer cumulus clouds; and 2) development of precipitation in clouds and the resulting surface rain entities

Characteristics of Summer Radar Echoes in Arizona, 1956

This report describes an investigation of the radar data obtained during the summer of 1956. Descriptions of the evaluation and analysis techniques, of the basic data and of the findings of this study are given in considerable detail. For the convenience of the more casual reader, all discussion and a summary of the findings are contained in sections VI and VII.Part of the research was sponsored by the Geophysics Research Directorate of the Air Force Cambridge Research Center under contract AF 19 (604)-1931 with the University of Chicago.This title from the Institute of Atmospheric Physics Reports collection is made available by the Department of Hydrology & Atmospheric Sciences and the University Libraries, University of Arizona.
