This work presents an analysis of the climate change scenarios in some extreme precipitation indices over Spain using simulations from the EURO-CORDEX project. Change projections of precipitation are evaluated for the near future (2021-2050) relatively to a reference past climate (1971-2000). Projections of annual precipitation show a general decrease in almost the whole region except over the central area where positive changes are detected due to a significant increase in winter. For consecutive wet days, an annual decrease is also projected over the country attributable to a significant decrease mainly observed in spring and to a lesser extent in winter. On the other hand, consecutive dry days are projected to be higher overall as a result of significant increases in spring, summer and autumn. Positive changes are also projected for the maximum daily precipitation during winter and autumn.
本研究利用 EURO-CORDEX 项目的模拟结果,分析了西班牙部分极端降水指数的气候变化情景。相对于参考过去气候(1971-2000 年),评估了降水的近期(2021-2050 年)变化预测。年降水量的预测显示,除了由于冬季显著增加而检测到正变化的中心区域外,几乎整个地区的降水量都普遍减少。对于连续湿润天数,由于主要在春季和较小程度上在冬季观察到的显著减少,预计该国的年降水量也会减少。另一方面,由于春季、夏季和秋季的显著增加,预计连续干燥天数总体上会更高。冬季和秋季的日最大降水量也预计会出现正变化。
