An air mass is a large body of air with uniform temperature and humidity, which takes on the characteristics of the area where it forms, or "source region". They form when air remains stagnant over a large area of uniform surface (like an ocean or large landmass) for days or weeks, allowing the air to acquire the surface's temperature and moisture properties.% Row Count 9 (+ 8)

A nor'easter is a strong area of low pressure along the East Coast of the United States that typically features winds from the northeast bringingmPair from over the Atlantic Ocean. Nor'easters are most often associated with strong winter storms crawling up the Northeast coast, but snow isn't a requirement for such a storm. These storms are most frequent and strongest between September and April, but can bring cool fair weather during the summer.% Row Count 10 (+ 9)

As an air mass moves over a new environment, it changes its temperature, moisture content, and stability by interacting with the new surface. For example, a cold, dry air mass will warm and become more humid if it moves over a warm ocean, while a warm air mass moving over a cold surface will cool down% Row Count 9 (+ 7)

An atmospheric river is a long, narrow band of water vapor that forms over oceans and is carried by winds. The Pineapple Express is a specific type of atmospheric river that picks up warm, moist air near Hawaii and transports it to the West Coast of North America, where it can cause heavy rainfall and snow.% Row Count 9 (+ 7)
