Number of days for Minimum Temperature over 90th percentile for Current Climate (1950-1999)

Model Run: Control - Current Climate (Observed/current climate as modelled by climate model). The Self-Organizing Map Downscaling (SOMD) was developed at the Climate Systems Analysis Group (CSAG)[1], University of Cape Town. This is a leading empirical downscaled technique and provides meteorological station level response to global climate change forcing (See Hewitson and Crane (2006) for methodological details and Wilby et al. (2004) for a review of this and other statistical downscaling methodologies). Downscaling of a General Circulation Model (GCM) is accomplished by deriving the normative local response from the atmospheric state on a given day, as defined from historical observed data.

模型运行：控制-当前气候（由气候模式模拟的观测/当前气候）。自组织映射降尺度（SOMD）由开普敦大学气候系统分析小组（CSAG）开发[1]。这是一种领先的经验降尺度技术，能够提供气象站尺度对全球气候变化强迫的响应（方法学细节参见Hewitson与Crane（2006），该技术及其他统计降尺度方法学综述参见Wilby等人（2004））。全球环流模式（GCM）的降尺度通过从历史观测数据定义的特定日期大气状态中推导规范性局地响应来实现。[1] http://www.csag.uct.ac.za/
