La Nina could impact Ottawa’s winter weather [Video]

Environment Canada’s senior weather climatologist says Ottawa will see “more of a winter than last year,” as it experiences a possible La Nina weather event this year.

The National Oceanic and Atmospheric Administration’s Climate Prediction Center says there is a 60 per cent chance of a weak La Nina event developing this winter. La Nina is part of a natural climate cycle that can cause extreme weather across the planet, and La Nina is the cool phase of the El Nino-Southern Oscillation.

Environment Canada says La Nina is the “appearance of cooler than normal weather in the eastern and central Pacific Ocean. It occurs due to increases in the strength of normal patterns of trade wind circulation.”
