interannual

The interannual variability of typhoons was random. Compared with Taipei and Haikou, the study erea were more frequently and severely suffered from typhoons, which concentrated from early June to early December and even last longer in years.

台风年际变化具有随机性；且与台北、海口两地相比，研究区台风的年发生次数更多，致灾更严重，集中月份为6月上旬～12月上旬，年内持续时间更长。

The quasi-stationary ridge over the northeastern Pacific only decides the climatological distribution of AWB, but significantly affects its interannual variability.

位于东北太平洋的准定常高压脊不仅决定着冬季北太平洋AWB频数的气候态分布，其强度和位置的改变对AWB频数的年际变化也有显著的影响。

Therefore, not only can this model simulate the ENSO variability over tropical Pacific, but also reproduce the ENSO related interannual variability of global atmosphere.

因此，该模式不仅能较好地再现热带太平洋的ENSO变化性，而且能较好地再现ENSO引起的全球大气环流的年际变化性。
