'''Teleconnection''' in [[atmospheric science]] refers to climate anomalies being related to each other at large distances (typically thousands of kilometers). The most emblematic teleconnection is that linking sea-level [[pressure]] at [[Tahiti]] and [[Darwin, Northern Territory|Darwin]], Australia, which defines the [[Southern Oscillation]].

大气科学中的遥相关是指气候异常在很大的距离上相互关联(一般为数千公里)。最典型的遥相关是连接塔希提岛和澳大利亚达尔文的海平面气压，它定义了南方涛动。

Teleconnections were first noted by the British meteorologist [[Sir Gilbert Walker]] in the late 19th century, through computation of the [[correlation]] between [[time series]] of [[atmospheric pressure]], temperature and rainfall. They served as a building block for the understanding of [[Climate variability and change|climate variability]], by showing that the latter was not purely [[random]].

英国气象学家吉尔伯特 · 沃克爵士在19世纪末通过计算大气压力、气温和降雨量的时间序列之间的相关性，首次注意到了遥相关。它们是理解气候变化的基石，因为它们表明气候变化并非完全随机的。
Indeed, the term [[El Niño–Southern Oscillation]] (ENSO) is an implicit acknowledgment that the phenomenon underlies variability in several locations at once. It was later noticed that associated teleconnections occurred all over North America, as embodied by the [[Pacific–North American teleconnection pattern]].

事实上，厄尔尼诺-南方涛动(ENSO)这个术语暗示了一种认识，即这种现象是几个地区同时发生变化的基础。后来人们注意到，相关的遥相关发生在整个北美洲，具体表现为太平洋-北美洲的遥相关模式。

In the 1980s, improved observations allowed detection of teleconnections at larger distances throughout the troposphere. Concomitantly, the theory emerged that such patterns could be understood through the dispersion of Rossby waves due to the spherical geometry of the Earth. This is sometimes called the "proto-model".
在1980年代，改进的观测使得在整个对流层的更大距离上探测遥相关成为可能。与此同时，理论表明这种模式可以通过由于地球的球面几何学而产生的 Rossby 波的弥散来理解。这有时被称为“原始模型”。

由于热带海洋表面温度可以提前两年预测，遥相关模式的知识可以为偏远地区提供某种程度的可预测性，有时候可以预测几个季节。例如，预测厄尔尼诺现象可以预测北美洲的降雨、降雪、干旱或气温模式，提前几周到几个月。在吉尔伯特 · 沃克爵士的时代，强烈的厄尔尼诺现象通常意味着较弱的印度季风，但是这种反作用关系在20世纪80年代和90年代已经减弱，原因是有争议的。

For instance, predicting [[El Niño]] enables prediction of North American rainfall, snowfall, droughts or temperature patterns with a few weeks to months lead time. In [[Sir Gilbert Walker]]'s time, A strong El Niño usually meant a weaker [[Monsoon#Global_monsoons|Indian monsoon]], but this [[anticorrelation]] has weakened in the 1980s and 1990s, for controversial reasons.{{fact|date=January 2014}}

由于热带海洋表面温度可以提前两年预测，遥相关模式的知识可以为偏远地区提供某种程度的可预测性，有时候可以预测几个季节。例如，预测厄尔尼诺现象可以预测北美洲的降雨、降雪、干旱或气温模式，提前几周到几个月。在吉尔伯特 · 沃克爵士的时代，强烈的厄尔尼诺现象通常意味着较弱的印度季风，但是这种反作用关系在20世纪80年代和90年代已经减弱，原因是有争议的。
