Abstract:
In this paper,a quantitative model simulating the effect of climate on dust storm frequency was presented and the climate effect on dust storm frequency in northan middle regions of Ningxia was studied.Meteorological records of many years in six meteorological stations were applied to evaluate the climatic influential index and to simulate the actual dust storm frequency.
Key words: north and middle region of Ningxia , dust storm frequency, climatic effecting index model
摘要:
从形成沙尘暴天气的动力机制、热力条件及物质基础入手,定性地分析了月平均风速、湿润度指数、月地面温差及下垫面沙化程度对沙尘暴频率的影响,在此基础上借鉴最新研究进展,建立适合宁夏中北部地区沙尘暴频率气候影响指数模型,比较深入地分析了宁夏中北部地区气候因素对沙尘暴频率的影响。
关键词: 宁夏中北部地区, 月沙尘暴频率, 气候影响指数模型
