我国沙尘天气研究的最新进展与展望

国内外学者普遍关注对沙尘天气时空分布格局的研究,非常重视对沙尘天气动力机制的分析,广泛采用多种方法分析沙尘天气的发生发展过程,一贯强调对沙尘天气发展趋势的预测,不断尝试对沙尘天气灾害与防治的探索。随着对沙尘天气研究的不断深入,人们逐渐明确了沙尘天气的时空分布特征,深刻揭示了我国沙尘天气的主要沙尘源地和移动路径,对沙尘天气形成机理与机制的认识不断深化,沙尘天气的预报、预警及其综合防治等方面的研究也取得了重大进展。从发展趋势来看,建立有效的沙尘天气监测预警系统,加强对沙尘天气发生和发展机理研究,强化对关键区域沙尘天气预警预报与综合防治将是今后研究的重要方向。

Progress and Prospect of Research on Sand-dust Weather in China

The authors reviewed the research progress at home and abroad about the theories, ideas, methods and practices of the research on sand-dust weather of China, then put forward the uniform concept and classification standards of sand-dust weather, finally, pointed out the leading research fields and prospected the main research directions in the future. Studies showed that scholars generally paid close attention to the research on spatial-temporal distribution of sand-dust weather in China, and thought much on the analysis to dynamical mechanism of sand-dust weather. They generally adopted multiplicative analytical method to study the generant and developmental process of sand-dust weather, and stressed the forecast of sand-dust weather tendency. With the deepening of research, they have got more knowledge about the spatial-temporal characteristics, and have disclosed the main sand sources and the moving routes of sand-dust weather in China. Besides, the cognition to the forming mechanism was deepened, and some important progresses have been obtained on sand-dust storms forecasting, fore-alarming and comprehensive control. Viewed from research developing trend, the main research directions in the future are establishing an effective monitoring and fore-alarming system, strengthening research on developmental mechanism, forecasting, fore-alarming and comprehensive controlling of sand-dust weather.
