It is based on optimization of both the considered area and the time duration for every event. The method consists of three steps: (i) estimation of return periods of a representative variable at individual sites, performed separately for various time windows; (ii) spatial interpolation of the point return period data; and (iii) averaging of return period values from individual pixels and optimization of the considered area and the time window. The optimization is enabled by multiplication of the common logarithm of the geometric mean of return periods by the radius of a circle area equivalent to the considered area. The maximum product is referred to as the Weather Extremity Index (WEI). The method is demonstrated by two precipitation events that affected the Czech Republic in May and in August 2010.
