E-OBS 降水网格数据集 v.10.0 用于检测 1957-2013 年雨季（9 月至 4 月）整个地中海盆地的极长干旱期 (VLDS) 事件。主要目标是根据位置、空间范围、持续时间和时间变化将这些事件描述为气候对象。在本研究中，在地中海盆地检测到 76 起 VLDS 事件，并分为四种空间模式：分散局部（25 起事件）、东北地中海（11 起事件）、西地中海（15 起事件）和东南地中海（25 起事件）。每种模式都显示事件的季节性。大多数分散的局部事件、东北部和东南部事件开始于九月，即雨季开始时。相比之下，大多数西地中海活动都在雨季中期开始。随着时间的推移，每个季节受 VLDS 事件影响的累计天数略有增加，但并不显着。
The E‐OBS precipitation gridded data set v.10.0 is used to detect very long dry spell (VLDS) events over the entire Mediterranean Basin for the 1957–2013 period, during the wet season (September to April). The main objective is to characterize these events as climatic objects, in terms of location, spatial extent, duration, and temporal variability. In this study, 76 VLDS events were detected in the Mediterranean Basin and grouped into four spatial patterns: scattered localized (with 25 events), northeast Mediterranean (11 events), West Mediterranean (15 events), and southeast Mediterranean (25 events). Each pattern shows seasonality in events. Most of the scattered localized, northeast, and southeast events begin in September, at the beginning of the wet season. In contrast, most of the West Mediterranean events begin in the middle of the wet season. Over time, there is a slight but not significant increase in the cumulative number of days per season affected by VLDS events.
