Area-depth studies for thunderstorm rainfall in Illinois

Areal Frequencies of Hail and Thunderstorm Days in Illinois

Hail and thunderstorm statistics for the 1951-60 period obtained from 119 U.S. Weather Bureau stations in Illinois were conlbined n-ith crop-hail insurance data for this same period for performing a detailed climatological investigation of the frequencies of hail days and thunderstorm days in Illinois. In the crop-growing season thunderstorms occur on 1 out of every 2 days on the average and ha...

Stochastic Models of Spatial and Temporal Distribution of Thunderstorm Rainfall

A simplified stochastic model based on airmass thunderstorm rainfall data from the 58-square-mile Walnut Gulch Experimental Watershed in south eastern Arizona is being developed at the Southwest Watershed Research Center, Tucson, Ariz. Records from the 95 rain gage network on this watershed pro vide valuable information on airmass thunderstorm rainfall in the Southwestern United States. Proba b...

two case studies to introduce a method for thunderstorm forecasting

thunderstorm is one of the most dangerous phenomena in aviation because the greatest number weather hazards such as icing, turbulence, wind shear, lightning hail are combined in one single source, the thunderstorm. spatial characteristics of thunderstorms which can be associated with irreparable outcomes are known by most of the forecasters. tornadoes, microbursts, very strong winds and flash f...

Spatial Variability in Rainfall Erosivity versus Rainfall Depth: Implications for Sediment Yield

ity in rainfall erosivity and associated sediment yield. Rainfall erosivity and sediment yield can be measured Rainfall depth within small semiarid watersheds can have high much more cost effectively than runoff, an important spatial variability, but spatial variability in rainfall erosivity, a more direct determinant of sediment yield, has not been quantified. Using consideration when studying...
