Regional Patterns of the Diurnal Properties of Heavy Hourly Precipitation*     

Julie A. Winkler 《The Professional geographer》1992,44(2):127-146

Heavy precipitation is one of the most significant natural hazards in the United States today. Knowledge of the climatography, including the temporal characteristics, of this phenomenon is necessary in order to better plan, design for, and predict this hazard. In this study, cluster analysis is used to simplify and clarify the spatial patterns in the time of day heavy precipitation most frequently occurs. Regions with similar diurnal properties are delineated, and the substantial seasonal fluctuations in the regional patterns are traced. Of particular interest is the expansion during the cool season and contraction during the warm season of the nocturnal precipitation regime in the central United States.  相似文献   

SOIL QUALITY IN ILLINOIS—AN EXAMPLE OF A SOILS GEOGRAPHY RESOURCE ANALYSIS∗     

《The Professional geographer》2013,65(2):127-136

Although acts of creation, scientific or artistic, result from metaphorical and mythological speculations, the role of metaphor and myth has largely been neglected in attempts to develop a geographical epistemology. The significance of these concepts is illustrated by the use of the frontier symbol as a means of understanding both the social structure of the contemporary black inner city and the temporal dimension of the recent expansion of human activities into nighttime.  相似文献
