Global weather patterns influence each other, affecting Eastern Canada and the US

Teleconnections are atmospheric links that allow weather patterns in distant regions to influence each other. A prime example is the El Niño-Southern Oscillation, where pressure changes in South America and Australia affect Pacific Ocean temperatures and global weather. Another is the North Atlantic Oscillation, which affects Eastern Canada and the U.S. East Coast weather. The Arctic Oscillation is a teleconnection tracking the polar vortex. A positive phase keeps cold air in the Arctic, while a negative phase allows colder air to move south. Meteorologists study these teleconnections, like the NAO and AO, to improve long-range weather forecasting accuracy. Early research, such as the Southern Oscillation, demonstrated the interconnectedness of global weather patterns. Understanding how these teleconnections work allows for improved predictions, helping to prepare for varied temperature changes and precipitation.
