Abstract: This paper identifies temporal and spatial patterns in the diurnal cycle of hourly warm season precipitation events over the Great Plains of the United States. Results from 30 years of hourly precipitation records from 515 ...

Abstract: The international border running through the Sonoran Desert in southern Arizona and northern Sonora is marked by a sharp discontinuity in albedo and grass cover. The observed differences in surface properties are a result ...

Abstract: In this investigation, how annual water use in the city of Phoenix, Arizona, was influenced by climatic variables between 1980 and 2004 is examined. Simple correlation coefficients between water use and annual mean ...

Abstract: The purpose of this study was to analyze the time and space variations in long-term monthly-averaged daily percent possible solar radiation levels in the United States. Both principal components analysis and harmonic ...

Abstract: Summertime temperature, dewpoint, relative humidity, apparent temperature and weather stress levels have not changed significantly over the past 37 years at the Tucson, Arizona Municipal Airport. However, several of these ...

Abstract: The association between a developing urban heat island and local monthly averaged wind speeds is examined in this investigation. Results from a series of statistical analyses show a significant increase in wind speeds in ...

Abstract: Hourly winter (November?March) precipitation data were assembled for nearly 5000 stations in the conterminous United States over the period 1948?98. Despite a potential observation bias in the 24th hour, a general tendency ...
