Understanding Cold Waves: A Comprehensive Guide for Beginners

A cold wave is a significant weather event characterized by a rapid and considerable drop in temperature over a large area within a short period, typically 24 hours. This phenomenon can occur at any time of the year and in various locations worldwide. (ebsco.com)

What Causes Cold Waves?

Cold waves are primarily caused by the movement of large, dense air masses from colder regions, such as northern Canada or Siberia, into warmer areas. These air masses are often associated with high-pressure systems that stabilize the colder air. The interaction between different air masses and the jet stream contributes to the formation of cold waves. (ebsco.com)
