摘要
热带季节内振荡是延伸期预报的主要来源,基于热带季节内振荡的延伸期预报研究对业务预报具有重要意义。系统回顾了近几年热带季节内振荡在延伸期降水、温度及其极端事件、台风和季风等方面的预报应用中的最新成果以及热带季节内振荡在主要预报业务中心的应用现状,总结了热带季节内振荡在延伸期预报应用中具有的一定理论支撑;最后分析了热带季节内振荡在延伸期预报应用中面临的预报对象的确立、当前动力模式的模拟、与气象要素的物理联系及影响预报的检验等方面的技术难点,并指出了热带季节内振荡影响预报在集合预报和多模式集成及加强多种季节内振荡对天气影响的研究等方面的未来发展趋势。
Tropical intraseasonal oscillation(MJO)is the main source of the extended range forecast.The research of the extended range forecast based on MJO is of great significance for the operational forecast.In this paper,the latest achievements of MJO in the prediction of precipitation,temperature and their extreme events,typhoon and monsoon in the extended range and the operational status of major prediction centers in which MJO is used for real-time monitoring and prediction were reviewed systematically.The theoretical support of MJO in the prediction of the extended range was summarized.Finally,the technical difficulties of MJO in the application of the extended range forecast,such as the establishment of forecast objects,the simulation of MJO by the current dynamic model,the physical connection between MJO and meteorological elements,and the evaluation of MJO’s influence forecasting were analyzed,and the future development trends of MJO influence forecast in the ensemble forecast,multi-mode integration and strengthening the research on the influence of multiple seasonal oscillations on the weather were also pointed out.
