Abstract
During a period characterized by widespread evidence of climate change, with a tendency to extreme weather events, understanding the signals relating to short and intense rainfall rather than those extended plan is crucial to human activities including but allows to consider intervention in Civil Protection operations in the event of flooding or other problems hydrogeological scenarios. Analysis of weather data for the period 1950-2010, for eleven weather stations in the territory of Molise - representative of the central Adriatic coast of the Italian peninsula - has shown that on an annual basis, the totals for mountain and coastal areas decease significantly while it tends to increase in areas of medium hill. A very different signal is observed for short and intense rainfall in which a significant increase is observed only on the coast. The distribution of intense events is no longer limited to the summer months (convective storms) and the first part of the fall (advective storms) in particular, on the coast and in the hinterland, these phenomena become more frequent until early winter. This is probably due to the warming of the Adriatic Sea during the last years.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
