摘要

摘要大气阻塞是造成极端天气的最常见原因。本文利用模式数据研究了北极涛动指数与大气阻塞特征之间的关系。本文估算了阻塞持续时间和强度与阻塞初期主模式指数（或相位）的关系。考虑了一个典型的阻塞事件，结果表明，区域熵积分值的增加可以作为动态机制变化的指标。

Numerical Study of the Arctic Oscillation Impact on the Atmospheric Blocking Characteristics

Abstract

Atmospheric blocking is the most common cause of extreme weather conditions. In the present paper, model data are used to investigate the relationship between the Arctic Oscillation index and the characteristics of atmospheric blocking. The dependence of the duration and intensity of blocking on the index (or phase) of the principal mode during its initial period is estimated. A typical blocking episode is considered, and it is shown that increased values of integral regional enstrophy can be an indicator of the change in the dynamic regime.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
