Mean potential evaporation in the hydrological winter half year for the 30-year period 2021-2050, No climate protection scenario (RCP8.5)

The map shows the mean potential evaporation (in mm) in the hydrological winter half-year (Nov.-Apr.) for the 30-year period 2021-2050 under the “No-Climate Protection” scenario (RCP8.5). The basis for the presented potential evaporation is the daily potential evaporation according to the standard procedure of the FAO for the determination of grass reference evaporation. The climate models are powered by the “No Climate Protection” scenario (RCP8.5). This is a scenario of the IPCC, which describes a continuous increase in global greenhouse gas emissions, which by the end of the 21st century generates an additional radiative forcing of 8.5 watts per m² compared to pre-industrial levels. The results of all climate models are equally likely. Therefore, in addition to the mean that shows a tendency, the upper (maximum) and lower (minimum) edges of the result bandwidth can be retrieved via the MapTip.本地图展示了"无气候防护"（No-Climate Protection）情景（典型浓度路径8.5，RCP8.5）下，2021-2050年30年周期内水文冬季半年（11月至次年4月）的平均潜在蒸散发（单位：毫米）。 本次呈现的潜在蒸散发数据，其计算基础为遵循联合国粮食及农业组织（Food and Agriculture Organization，FAO）测定草地参考蒸散发的标准规程得到的逐日潜在蒸散发。 所用气候模式基于"无气候防护"（No-Climate Protection）情景（RCP8.5）构建。该情景由政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）提出，描述了全球温室气体排放持续增长的态势：至21世纪末，相较于工业化前水平，该情景将带来额外8.5瓦每平方米的辐射强迫。 所有气候模式的模拟结果权重均等。因此，除了能够体现变化趋势的平均值外，用户还可通过地图提示（MapTip）获取结果区间的上限（最大值）与下限（最小值）。
