Air Masses & Fronts

Air, based on temperature, moves across the surface of the earth. These large masses of warm or cold air are called fronts. Scholars model different air masses containing various temperatures and create both cold and warm fronts.

Students examine dynamic interaction between North American air masses and often spectacular and extreme weather patterns that result, explore nature and origin of five major air masses that affect Canada's weather, and investigate...

Meteorology learners explore the weight of air, layers of the atmosphere, and air pressure action through a series of discussions, demonstrations, and hands-on group activities. Enough discussion prompts, background information, student...

On a hot summer day, in a two-story home with no air conditioning, the coolest place is in the basement and the warmest place is on the second floor. See how warm air rises and cool air sinks through a hands-on activity. Class...

Here is a comprehensive and colorful collection of slides to introduce 4th - 8th graders to all things weather-related. The factors that contribute to weather are defined, types of clouds and the related conditions are explained, air...

Convection is offered as the reason behind our weather phenomena. This presentation assumes that viewers are familiar with the methods of heat transfer, and is therefore more geared toward middle-school meteorologists. The focus is on...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

Young meteorologists examine the four main types of weather fronts and how they appear on a weather map. Participants learn about the difference between the types of weather fronts along with their distinguishing features. A...

Introduce your class to air masses and how they affect the weather with a lesson that focuses on the differences between high and low air pressure systems. The class explores actual weather data using archived weather data.

Four types of air masses interact in the atmosphere above the US. The collision of these air masses forms a front, which, in turn, creates our weather. Concepts are explained by Sam and RJ, thus preventing a snowball fight. Your class...
