The North Pacific Ocean is the most active region on our planet in terms of tropical cyclone (TC) activity. These storms are responsible for numerous fatalities and economic damages, affecting the livelihood of those living in the impacted areas. Historically the examination of TCs in the North Pacific Ocean has been performed separately for its two main sub-basins: the West North Pacific and the East North Pacific. Here, we consider the TC activity in the North Pacific as a single basin and examine the climate processes responsible for its number of TC days. We show that the Pacific Decadal Oscillation modulates the number of TC days in the North Pacific Ocean through its connection to the sea surface temperature. The insights from this work will advance the understanding of the climate processes responsible for these storms, and will provide valuable information toward our preparation and adaptation efforts on long timescales.

太平洋年代际振荡在北太平洋年际时间尺度上调节热带气旋日数

就热带气旋 (TC) 活动而言，北太平洋是地球上最活跃的地区。这些风暴造成了无数人死亡和经济损失，影响了生活在受影响地区的人们的生计。历史上，北太平洋 TC 的检查是对其两个主要子盆地分别进行的：西北太平洋和东北太平洋。在这里，我们将北太平洋的 TC 活动视为一个单一的盆地，并检查导致其 TC 天数的气候过程。我们表明，太平洋年代际涛动通过其与海面温度的联系来调节北太平洋的 TC 天数。这项工作的见解将促进对造成这些风暴的气候过程的理解，
