Teleconnections are large-scale climate phenomena linking distant regions of the Earth's atmosphere and oceans. They influence weather patterns and climate variability across different parts of the globe.
Interactions between atmospheric circulation patterns, sea surface temperatures, and other climatic variables on regional and global scales cause them.
They play essential roles in modulating weather and climate conditions worldwide. They can lead to climate anomalies, such as temperature extremes, precipitation anomalies and atmospheric pressure changes, over vast distances.
When forecasters understand them, they can better predict the weather, especially extreme weather events and long-term climate trends.
Learning about them allows forecasters to improve climate models, helping people learn to adapt to changing weather better.
