【 摘 要 】

Opposite to some drought indices, a new proposal for a spatial index is made according to the area that suffers drought. Although median values may change from one state to another, they show a clear skewness towards xerochoric conditions. In peninsular Spain light droughts arise until the territory is dry up to 69%, moderate droughts up to 84%, severe droughts up to 92% and extreme drought up to 100%. In Poland values are quite similar, so that this method may de considered of continental validity. At the end a classification of months into 7 groups (called “septosects�?) is made, which results in almost the same as cumulative percentage deviations elsewhere.
