How to read the map: Warm spell duration index is defined as a period (number of days) of six consecutive days with the mean daily temperature exceeding 90th percentile of the baseline temperature (average daily temperature the 1961-1990 period). Stations with negative trends are blue and stations with positive trends are in red colour. When stations are in green colour trends are not statistically significant at 25% level.
