摘要:

开展10 ~ 30 d 延伸期天气预报对于气象防灾减灾具有重要意义,也是填补短中期天气预报和短期气候预测之间的间缝隙、构建完备性预报体系的必然要求。本文从延伸期天气预报的预报对象、基本方法和相关原理以及国内外业务实践3 方面回顾了延伸期预报的科学进展和业务现状,从数值方法、大气低频信号演变方法和数理统计方法3 个角度比较分析了延伸期预报的各种主流方法,详细探讨了各种方法的优势和不足,在此基础上对目前延伸期预报领域存在的问题进行了梳理和总结。

Abstract:


Developing extended - range weather forecast from 10 to 30 days is very important for preventing and reducing meteorological
disasters,which is also necessary to fill the gap between short - to - medium range weather forecast and short - term climate prediction.
In this paper,the forecast object,basic methods and related mechanisms,and operational applications at home and abroad about extended
- range weather forecast are reviewed. Several methods about extended - range weather forecast are compared and analyzed from
three aspects of numerical modeling,development of low - frequency atmospheric oscillation and numerical statistics,and the advantages
and disadvantages of all kinds of prediction methods are dicussed in detail. Finally,the scientific problems in the field of extended
- range weather forecast are summarized.

Key words: extended - range weather forecast, predictable components, MJO, low - frequency synoptic chart, synoptic processe
