在过去的40年中，热带气旋累积气旋能量（ACE）在全球范围内表现出非常大的年际变化。在2006年以来的候，北方和全球热带气旋ACE急剧减少，降至20世纪70年代末以来的最低水平。此外，全球热带气旋的频率已达到历史最低水平。这里的证据表明，相当大的变化，热带气旋ACE与观察到的大尺度气候机制，包括厄尔尼诺南方涛动和太平洋年代际振荡的特征的演变。与2010年北太平洋热带气旋活动创纪录的平静相比，北大西洋海盆仍然非常活跃，占整个日历年全球ACE的近三分之一。引文：Maue，R.

Tropical cyclone accumulated cyclone energy (ACE) has exhibited strikingly large global interannual variability during the past 40-years. In the pentad since 2006, Northern Hemisphere and global tropical cyclone ACE has decreased dramatically to the lowest levels since the late 1970s. Additionally, the global frequency of tropical cyclones has reached a historical low. Here evidence is presented demonstrating that considerable variability in tropical cyclone ACE is associated with the evolution of the character of observed large-scale climate mechanisms including the El Nino Southern Oscillation and Pacific Decadal Oscillation. In contrast to record quiet North Pacific tropical cyclone activity in 2010, the North Atlantic basin remained very active by contributing almost one-third of the overall calendar year global ACE.
