Abstract: Among all atmospheric hazards, heat is the most deadly. With such recent notable heat events as the Chicago Heat Wave of 1995, much effort has gone into redeveloping both the methods by which it is determined whether a day ...

Abstract: A relative climatological index is developed to evaluate interregional variations in human discomfort and the impacts of weather on a variety of socioeconomic parameters. The ?weather stress index? is designed to assess ...

Abstract: The objective of this study is to provide an evaluation of the magnitude of apparent temperature and the weather stress index (WSI) in winter across the United States. In addition, two extremely cold winters, 1976?77 and ...

Abstract: The heat stress index (HSI) is a new, comprehensive summer index that evaluates daily relative stress for locations throughout the United States based on deviations from the norm. The index is based on apparent temperature ...

Abstract: The selection of the proper clustering procedure to use in the development of an objective synoptic methodology may have far-reaching implications on the composition of the final ?homogeneous? groupings. The goal of this ...

Abstract: Studies which utilize a long-term temperature record in determining the possibility of a global warming have led to conflicting results. We suggest that a time-series evaluation of mean annual temperatures is not sufficiently ...

Abstract: his study examines the impact of a changing climate on heat-related mortality in 40 large cities in the United States. A synoptic climatological procedure, the spatial synoptic classification, is used to evaluate present ...

Abstract: It has been suggested that previous results indicating an increase in surface temperatures over the past 40 years within the coldest air masses at four stations in the western North American Arctic may be attributed to the ...

Abstract: The Philadelphia, Pennsylvania, Hot Weather?Health Watch/Warning System was initiated in 1995 to alert the city's population to take precautionary actions when hot weather posed risks to health. The number of lives saved ...

Abstract: Last summer, Philadelphia, Pennsylvania, instituted a new Hot Weather-Health Watch/Warning System (PWWS) to alert the city's residents of potentially oppressive weather situations that could negatively affect health. In ...
