本文总结了近十年来热带-极地遥相关研究的进展。阐明厄尔尼诺-南方涛动（ENSO）对高纬度地区的影响仍然是不同研究领域的一个重要焦点。在季节内时间尺度上也发现了与马登-朱利安振荡（MJO）相关的热带与极地的联系。在几十年的时间尺度上，MJO相位的变化会导致两个半球极地地区的温度和海冰变化。此外，热带西太平洋、热带大西洋和北大西洋海温的长期变化与南极半岛周围的冬季快速变暖有关，而热带中部太平洋海温的变化与南极洲西部的变暖有关。从热带发出的罗斯贝波列仍然是从季节内到十年时间尺度的热带和极地遥相关的关键机制。 ENSO 相关的热带海温异常通过调节副热带和中纬度地区的平均纬向风来影响高纬度环形模式。最近的研究还揭示了罗斯贝波与高纬度地区大气环流之间相互作用的细节。我们还回顾了过去热带地区和两极之间的一些假设联系，包括气候与当今根本不同的时期，特别是考虑到比当今更大的全球冰冻圈。除了来自热带地区的大气罗斯贝波之外，巨大的极地温度变化和放大（部分与轨道配置和太阳辐照度的变化有关）也影响了低纬度与高纬度的联系。
This paper summarizes advances in research on tropical–polar teleconnections, made roughly over the last decade. Elucidating El Niño–Southern Oscillation (ENSO) impacts on high latitudes has remained an important focus along different lines of inquiry. Tropical to polar connections have also been discovered at the intraseasonal time scale, associated with Madden–Julian oscillations (MJOs). On the time scale of decades, changes in MJO phases can result in temperature and sea ice changes in the polar regions of both hemispheres. Moreover, the long-term changes in SST of the western tropical Pacific, tropical Atlantic, and North Atlantic Ocean have been linked to the rapid winter warming around the Antarctic Peninsula, while SST changes in the central tropical Pacific have been linked to the warming in West Antarctica. Rossby wave trains emanating from the tropics remain the key mechanism for tropical and polar teleconnections from intraseasonal to decadal time scales. ENSO-related tropical SST anomalies affect higher-latitude annular modes by modulating mean zonal winds in both the subtropics and midlatitudes. Recent studies have also revealed the details of the interactions between the Rossby wave and atmospheric circulations in high latitudes. We also review some of the hypothesized connections between the tropics and poles in the past, including times when the climate was fundamentally different from present day especially given a larger-than-present-day global cryosphere. In addition to atmospheric Rossby waves forced from the tropics, large polar temperature changes and amplification, in part associated with variability in orbital configuration and solar irradiance, affected the low–high-latitude connections.
