遥相关 - 百度百科
观测事实表明，全球大气环流的变化和异常存在相关性，一个区域的环流异常可以引起距离遥远的另一个区域的环流异常，这种遥远距离的 大气环流 变化与异常间的相关联称为遥相关。 遥相关最早在1879年由Hiedbrandon提出。 3不同时间、不同空间的时空遥相关，如海气时空遥相关。 气候系统 中存在着大量的遥相关现象，这些大气环流变化和异常在空间上可以相距遥远，在时间上可以同时或有先后。 一般认为遥相关是由准定常行星波在球面大气中的传播及平均气流上的正压 …
Teleconnection - Wikipedia
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, Australia, which defines the Southern Oscillation.
遥相关 - 维基百科，自由的百科全书
大气科学 中的 遥相关 是指气候异常在很远的距离上（通常为数千公里）产生相互关联。 最具典型意义的遥相关是 塔希提岛 和澳大利亚 达尔文 的海平面 气压 “跷跷板”现象，亦即 南方涛动。 遥相关最早是由英国气象学家 吉尔伯特·沃克 爵士在19世纪后期通过计算 大气压力 、温度和降雨的 时间序列 之间的 相关性 发现的。 它们作为理解 气候变率 的基石，表明后者并非纯粹是 随机 的。 事实上， 厄尔尼诺-南方涛动 (ENSO) 一词本身就隐含着该现象同时在多个地点发生的含义。 …
What are teleconnections? Connecting Earth's climate patterns via ...
2022年12月22日 · What is a teleconnection? Teleconnections are significant relationships or links between weather phenomena at widely separated locations on earth, which typically entail climate patterns that span thousands of miles.
Teleconnections among tipping elements in the Earth system
2023年1月5日 · This work provides a concise and systematic framework to investigate the potential teleconnection among the tipping elements and can potentially be used to predict the abrupt changes caused by...
Teleconnection Introduction - Climate Prediction Center
2008年5月8日 · The term "teleconnection pattern" refers to a recurring and persistent, large-scale pattern of pressure and circulation anomalies that spans vast geographical areas. Teleconnection patterns are also referred to as preferred modes of low-frequency (or long time scale) variability.
CPC - Climate Weather Linkage: Teleconnections
2012年1月26日 · On March 3, 2022, several updates were made to the CPC Daily Teleconnections products. While the methodology used to calculate the teleconnection indices is unchanged, the statistics displayed in these graphics have changed slightly due to script updates and the utilization of the full ensemble size.
Teleconnections: Changes in Weather Linked Together
Changes in the atmosphere in one place can affect weather over 1000 miles away. Scientists are trying to sort out how this works so that they can better understand and predict weather patterns worldwide. They call these patterns teleconnections. Teleconnection patterns are caused by changes in the way air moves around the atmosphere.
Teleconnection - an overview | ScienceDirect Topics
Teleconnection is defined as a fundamental component of the climate system that involves climate variability links between geographically separated regions, often characterized by large zonal scale and small meridional scale wave patterns.
Pacific/North American (PNA) - Climate Prediction Center
2012年1月10日 · The Pacific/ North American teleconnection pattern (PNA) is one of the most prominent modes of low-frequency variability in the Northern Hemisphere extratropics. The positive phase of the PNA pattern features above-average heights in the vicinity of Hawaii and over the intermountain region of North America, and below-average heights located ...
