In this video, we explain the formation of air masses in a clear and exam-oriented manner. An air mass is a large body of air with uniform temperature and humidity, and it forms over specific regions known as source regions. The video covers: • What is an air mass? • Conditions required for the formation of air masses • Role of source regions (oceans, deserts, snow-covered areas) • Importance of high pressure, calm winds, and long residence time • Types of air masses (continental and maritime) •

Enhanced color Air Mass imagery via NOAA's GOES East satellite shows a strong low pressure system evolving off the coast of eastern North America from April 23-24, painting a vivid picture of dynamic atmospheric forces at play. | NOAA Satellite and Information Service

This Air Mass imagery that the GOES East satellite captured today shows a major winter storm pushing across the northern U.S. This type of imagery helps identify moisture and temperature characteristics of air masses.
