"The key driver behind these extremes is the jet stream—a fast-moving current of air high in the atmosphere that can sometimes become very wavy. These dips can cause different extremes to happen simultaneously in different parts of the country, such as a ridge of warm air in one region, and a trough of cold air in another."
"In March, we have some warm days, and then it turns sharply colder and snows. It's the kind of rollercoaster that we're used to. This kind, where one day it's very warm, and the next day it cools off quite a bit, is not out of the ordinary."
March has brought a mix of weather extremes across the US, including flooding in Hawaii, snow in Alabama, and a severe heatwave on the west coast. Experts emphasize the need for awareness of the climate crisis. While March is traditionally unpredictable, the current weather patterns are influenced by the jet stream, which can create simultaneous extremes in different regions. The interplay of warm and cold air masses is a key factor in these dramatic temperature swings.
