To evaluate the integral energetic effect of tropical cyclones, a special characteristic was used—an action with the dimension [energy] × [time]. Estimates of changes in the total action of tropical cyclones in the northwestern Pacific Ocean (NWPO) are obtained from observations for the period of 1951–2019. A significant increase in the interannual variability of the action of tropical cyclones in recent decades has been noted against the background of an increase in average values. There are also tendencies of an increase in the action of tropical cyclones and typhoons reaching extratropical latitudes, with significant interannual variations.

作为大气（气候）结构的一个整体特征的行动：对热带气旋的估计

为了评估热带气旋的整体能量效应，使用了一个特殊的特性——一个维度为[能量]×[时间]的动作。对西北太平洋 (NWPO) 热带气旋总作用变化的估计来自 1951-2019 年期间的观测。近几十年来，在平均值增加的背景下，热带气旋作用的年际变化显着增加。到达温带纬度的热带气旋和台风的作用也有增加的趋势，年际变化显着。
