摘要：
In this paper we continue to investigate the important parameter of global warming - a heat wave - that has no unique definition and represents the constellation of different factors such as e. g., heat index (temperature + humidity), time periods of excessive heat, etc. We find typical characteristics of heat indexes during different time periods, using most typical fuzzy expected values. Trapezoidal fuzzy sets are used to represent that characteristics. The results are compared with previous work based on the corresponding step-wise functions. We use the data collected in the Ministry of Preservation of the Environment of Georgia during 1955-1970 and 1990-2007.
