The developing El Ni\u00f1o has already exceeded previous records by some measures, raising questions about its influence on the coming winter. While wetter and stormier conditions are more likely during autumn, scientists are examining whether changes high above the Arctic could eventually allow colder air to reach Britain and Ireland.<\/p>\n\n\n\n

The resulting release of heat <\/strong>into the atmosphere influences circulation patterns around the world, although its effects vary considerably between regions.<\/p>\n\n\n\n
