Abstract

This study analyzes extreme anomalous hot and dry weather events in Israel based on a new definitionfor those events. Four thresholds of extreme hot and dry weather conditions are proposed. Thus, anextreme anomalous hot and dry day is defined when two conditions are fulfilled: The standard score ofthe temperature is above one of the four thresholds and the standard score of the relative humidity isbelow one of the four thresholds. The main conclusion of this study is that differences in temperatureand relative humidity in various geographic regions require a new definition for extreme anomaloushot and dry weather based on a regional basis and not on a unique one for the entire country throughoutthe year. By establishing various degrees for extreme anomalous hot and dry weather events based onthe monthly average and the standard deviation of maximum temperature values and minimum relativehumidity values for each region, one can get more accurate definition for those events. This approachmay be used worldwide and can serve to analyze possible climatic changes.
