Abstract
The aim of the present work is to study the dry spells along a marked rainfall gradient from the central part of the Duero basin, with an average annual precipitation below 400 mm, to Salamanca Rangeland, with precipitation recordings above 1000 m. Considering as dry days those with precipitations of = 0.1 mm, the results of the analysis show a high duration and frequency of dry spells for the overall zone: mean duration over 10 days and the mean duration of maximum dry spells is higher than 40 days. Although the study area is located in the northern part of Iberian Peninsula and the mountainous sector is important, this analysis indicates the Mediterranean climatic characteristics of the transect. However, the differences were noteworthy, according with the rainfall gradient, when threshold rainfalls (= 10 mm) related with water availability of ecosystems are used.
