Explore the global factors contributing to cold weather worldwide. From natural phenomena like polar vortex to seasonal changes discover the reasons behind chilly temperatures across the globe.
Polar Vortex
One major contributor to extreme cold events is the polar vortex. The polar vortex is a large area of low pressure and cold air surrounding both of Earth's poles. Occasionally, this vortex can weaken or split, bringing extremely cold temperatures to regions.
Arctic Air Masses
When masses of very cold air from the Arctic regions move southward, they can lead to a drop in temperatures. These Arctic air masses result in cold conditions.
Mountainous Terrain
High mountain ranges influence weather patterns and lead to extreme cold temperatures, especially on the windward side of the mountains. As air ascends over mountains, it cools rapidly, leading to cold temperatures on the other side.
Clear Sky and Radiational Cooling
Clear sky at night allows the Earth's surface to radiate heat into space, leading to rapid cooling of the air near the ground. This radiational cooling results in extremely cold nighttime.
Katabatic Winds
Katabatic winds are cold, dense winds that flow downhill under the influence of gravity. These winds originate from ice sheets and bring bitterly cold air to lower elevations.
Cold Fronts
Cold fronts are boundaries between warm and cold air masses. When a cold front passes through an area, it can bring a sudden drop in temperatures, leading to extreme cold weather conditions.
Ocean Currents
Ocean currents influence the temperature of nearby coastal regions. Cold ocean currents, such as the Labrador Current in the North Atlantic, contribute to colder temperatures in adjacent land areas.
Seasonal Changes
During certain seasons, especially winter, the tilt of the Earth's axis result in reduced sunlight and lower temperatures in certain regions, contributing to extreme cold weather.
