In this presentation the important parameter of global warming - a heat wave - is investigated. A heat wave 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. Typical characteristics of heat indexes during different time periods can be found, using most typical fuzzy expected values. Trapezoidal fuzzy sets are used to represent that characteristics. It is shown the appropriateness of rough sets for this problem.
