In this paper, the temporal tendencies of monthly, seasonal, and annual temperature data were analyzed in Friuli-Venezia Giulia (northeastern Italy) by applying two non-parametric tests for trend detection to 34 temperature series in 62 years (1940–2011), for which data are freely available online. As a result, an overall increase in the temperatures in both the minimum and the maximum values has been detected. In particular, regarding the maximum seasonal temperature data, a marked positive trend has been identified in all the seasons, except autumn, and especially in summer, with more than 80% of the stations showing increasing values. Similarly, a predominant positive trend characterized the minimum seasonal temperature data, especially in winter, when about 40% of the series showed this tendency.

摘要

In this paper, the temporal tendencies of monthly, seasonal, and annual temperature data were analyzed in Friuli-Venezia Giulia (northeastern Italy) by applying two non-parametric tests for trend detection to 34 temperature series in 62 years (1940–2011), for which data are freely available online. As a result, an overall increase in the temperatures in both the minimum and the maximum values has been detected. In particular, regarding the maximum seasonal temperature data, a marked positive trend has been identified in all the seasons, except autumn, and especially in summer, with more than 80% of the stations showing increasing values. Similarly, a predominant positive trend characterized the minimum seasonal temperature data, especially in winter, when about 40% of the series showed this tendency.
