Mr. Fetch’s Earth Science Classroom Air Masses A large body of air with similar -TEMPERATURE - HUMIDITY Warm Cold Temperature Moist Dry Humidity

Mr. Fetch’s Earth Science Classroom Air Masses’ Characteristics Source Regions Over warm area: the warm area makes the air above warm. Over water: water evaporates into the air above and makes it moist.

Mr. Fetch’s Earth Science Classroom Types of Air Masses 1. Maritime: (m) moist (marina/water) 2. Continental: (c) dry (continents/land) 3. Tropical: (T) warm (tropics) 4. Polar: (P) cold (poles) DESCRIPTION CONDITION LOCATION FORMED

Mr. Fetch’s Earth Science Classroom Types of Air Masses Maritime Tropical (mT) Continental Tropical (mP) Maritime Polar (mP) Continental Polar (cP)

Mr. Fetch’s Earth Science Classroom mP Maritime Polar Moist, cold air to west coast of the US. mT Maritime Tropical Moist, warm air to west coast of the Mexico. mT Maritime Tropical Moist, warm air to south east coast of the US. cT Continental Tropical Dry, warm to Desert SW mP Maritime Polar Moist, cold air to east areas of the Canada cP Continental Polar Dry, cold air to central and eastern US. Types of Air Masses

Mr. Fetch’s Earth Science Classroom Air Mass Modification mP Maritime Polar Moist, cold air to west coast of the US.
