摘要

本文综述了大西洋多年代际涛动(AMO)的研究历史，包括其动力学、全球遥相关、全球影响以及与全球平均地表温度的关系。AMO是一个全球尺度的海洋-大气耦合振荡气候系统，在所有海洋盆地都有显著的海表温度异常。它与大西洋经向翻转环流(AMOC)的显著振荡有关，这种振荡可能是由潮汐混合引起的潮汐重力强迫驱动的，并受到火山强迫和云辐射反馈的增强。AMO强烈影响所有大陆的地表气温(Tair)和帕尔默干旱严重指数(PDSI)。相位滞后在不同的大陆是不同的。在热带大陆上空，Tair和PDSI往往是同相的。在温带大陆上空，Tair和PDSI的相位往往不一致。AMO对全球平均地表温度和全球变暖中断有重要贡献。

The Atlantic Multi-Decadal Oscillation

ABSTRACT This paper reviews the history of research on the Atlantic Multi-decadal Oscillation (AMO), including its dynamics, global teleconnections, global impacts, and connection to global mean surface temperature. The AMO is a global-scale coupled ocean-atmosphere oscillation of the climate system with significant sea surface temperature (SST) anomalies in all ocean basins. It is associated with significant oscillation of the Atlantic Meridional Overturning Circulation (AMOC), which is likely driven by tidal gravitational forcing through tidal mixing and enhanced by volcano forcing and cloud-radiation feedback. The AMO strongly affects surface air temperature (Tair) and Palmer Drought Severity Index (PDSI) over all the continents. The phase lag varies among different continents. Over the tropical continents, Tair and PDSI tend to be in phase with each other. Over the extratropical continents, Tair and PDSI tend to be out of phase with each other. The AMO contributes significantly to global mean surface temperature and global warming hiatus.

期刊介绍： Atmosphere-Ocean is the principal scientific journal of the Canadian Meteorological and Oceanographic Society (CMOS). It contains results of original research, survey articles, notes and comments on published papers in all fields of the atmospheric, oceanographic and hydrological sciences. Arctic, coastal and mid- to high-latitude regions are areas of particular interest. Applied or fundamental research contributions in English or French on the following topics are welcomed: climate and climatology; observation technology, remote sensing; forecasting, modelling, numerical methods; physics, dynamics, chemistry, biogeochemistry; boundary layers, pollution, aerosols; circulation, cloud physics, hydrology, air-sea interactions; waves, ice, energy exchange and related environmental topics.
