Mean climate water balance for the 30-year period 2021-2050, No climate protection scenario (RCP8.5)

The map shows the average annual climate water balance (in mm) for the 30-year period 2021-2050 under the “No climate protection” scenario (RCP8.5). This indicator provides in the first approximation a measure of regional water availability and indicates whether the vegetation in an area may be affected by water shortages. The climatic water balance is calculated from the difference in rainfall and potential 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"无气候保护"情景（RCP8.5）下，2021-2050年这30年时段的年均气候水平衡（单位：毫米）。 该指标可初步表征区域水资源可利用量，并可反映区域内植被是否可能遭受水资源短缺影响。气候水平衡通过降雨量与潜在蒸散发量的差值计算得到。 气候模型基于"无气候保护"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量持续增长的态势：到21世纪末，相较于工业化前水平，其产生的额外辐射强迫将达到每平方米8.5瓦。 所有气候模型的结果均具有同等可信度。因此，除了体现趋势的均值之外，用户还可通过MapTip获取结果区间的上限（最大值）与下限（最小值）。
