Types of Air Masses Type of Air Mass Where it Forms Temperature Humidity Maritime Ocean Warm or Cold Moist Polar Near the poles Cold Dry Continental Land Warm or Cold Dry Tropical Tropics Warm Moist Maritime polar air masses are... cold and dry cold and moist warm and dry warm and moist A stalled front that may bring many days of clouds and precipitation is a(n) cold front occluded front stationary front warm front An air mass that forms over Arizona and New Mexico will be a Continental Polar Air Mass Continental Tropical Air Mass Maritime Polar Air Mass Maritime Tropical Air Mass Fill in the Blanks 1. A large body of air that has similar temperature, humidity, and air pressure at a given height is called a(n) air mass. These affect the weather.2. Air masses that form over oceans are called maritime air masses and air masses that form over land are called continental air masses.3. The boundary where air masses meet is a(n) front. Types of Fronts **There are 3 in each category** Warm Front warm air mass pushes a cold air mass - the warm air mass rises slowly brings storms and warmer temperatures Cold Front cold air mass pushes a warm air mass and forces the warm air up brings wind and colder temperatures Stationary Front two air masses pushing against each other without moving brings cloudy weather
