Available in PDF, EPUB and Kindle. Book excerpt: The frequency and probability of radar echoes of convective clouds over the United States are presented. Analysis of three years of observations from a 31-station WSR-57 weather radar network indicates that at all altitudes, radar echo probabilities are greatest over Florida and the Gulf coast, generally decreasing northward over the United States. Also, largest probabilities for most layers and locations occur in summer. Echoes have been reported up to at least 70 kft in May, June, and July, and up to 60 kft in winter. Diurnal variations reveal greatest probabilities between 1600 and 2100 LST in all regions. Largest mean monthly 3-hour values are 85 percent, and the maximum mean daily range is roughly 65 percent in the southeast during the summer months. The probability of an echo-free horizontal view near the earth's surface for a 100-mile range is also presented. Tabulations of echo-free sectors, as percent of the 360-degree radar scope, show that the probability of obstructions to a horizontal view increases generally from northwest to southwest during all seasons. The probability of having no echoes is greater in winter than in summer except along the Pacific coastal region. Diurnal variability is larger in July than in January. (Author)

Download or read book A Climatology of Very High Altitude Radar Precipitation Echoes written by Arthur J. Kantor and published by . This book was released on 1968 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frequency and percent occurrence of radar precipitation echoes from 50 to at least 70 kft over the United States is presented. Analyses of six years of data from a 31-station WSR-57 weather radar network indicate that probabilities of convective clouds are greatest over three regions: the Gulf Coast; a relatively narrow band northward through the central United States; and Florida. Largest probabilities at all levels and locations occur generally in summer, varying from May and June in central areas to August over south and southeast coastal regions. Based on mid-season months, maximum mean monthly probabilities are greater than 13% at 50-55 kft and nearly 1-1/2% at 60-65 kft near New Orleans in summer. In addition, precipitation echoes have been reported up to at least 70 kft at eight locations through the central United States in May through September, and up to 60 kft at a few Gulf coast stations in winter. Diurnal fluctuations at altitudes above 50 kft are such that largest probabilities are between 1600 and 2100 LST in all regions, with values approaching 10% at New Orleans and 7% at Tampa on an annual basis. Values for July are roughly three times larger than these at all stations. (Author)
