春季大风沙尘天气的气候特征及预报系统——以甘肃临夏州为例

Based on the conventional climatic data from 1955 to 2004 of the Linxia state in Gansu province, the gale sand-dust weather process and their climatological causes were comprehensively analyzed from aspects of terrain, landform, climate, and circulation characteristics. On this condition, the authors try to find new forecast thoughtway, and have established the short-term but real-time forecast system for spring gale sand-dust weather in Linxia. This system surpasses the conventional forecast tool, which can provide more scientific forecast basis for effectively protecting the atmospheric environment and reducing the loss of local people life and property in weather disasters.
