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.

北极涛动对大气阻塞特性影响的数值研究

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。
