What are air masses and where do they originate? What happens to the weather along fronts? Learn about warm and cold fronts and different types of advection. Maps and animated illustrations make these topics easier to comprehend.

A video and a short multiple-choice quiz on the topic of air masses and fronts. It describes the types of weather fronts, what an air mass is, and the four types of air masses in the US.

This Oklahoma Climatological Survey explores how air masses form, as well as the weather formations, which tend to appear on the edges of these masses in what is known as a front.

[Free Registration/Login may be required to access all resource tools.] Describes the weather fronts that occur when two air masses collide. Includes downloadable handouts.

Work samples, phenomena, assessment templates, and videos that directly address standard MS-ESS2-5: interacting air masses and weather.

This tutorial investigates how weather is influenced by the jet stream and air masses.

Why does a lot of hail, rain, or snow fall at some times and not others? This unit contains four separate lesson sets built around answering this question. In the first two lesson sets, students explain small-scale storms. In the third...

In this unit, students learn the basics about weather and the atmosphere. They investigate materials engineering as it applies to weather and the choices available to us for clothing to counteract the effects of weather. Students have...

Explains three forces of nature and how they impact the weather. These include infrared rays from the sun, differences in air pressure, and wind flow when hot and cold air masses meet. Supported by lots of visuals.

Students are introduced to air masses, with an emphasis on the differences between and characteristics of high - versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to...

This site discusses weather forecast computer modeling, or numerical weather prediction (NWP). It also discusses the development of the concept of front and air masses, as well as which computer forecast models are currently being used...

In this hands-on activity, students use their senses to describe what the weather is doing and to predict what it might do next. After gaining a basic understanding of weather patterns, students will become state park engineers and build...

In this interactive activity from NOVA Online you can move an air mass over a mountain and see how several distinct microclimates are created.

This Wikipedia site tells all about weather fronts, or boundaries between two air masses with differing characteristics. Includes many hyperlinked terms to additional information on related subjects.

A very detailed description of air masses, how they move and interact, and what weather takes place when this happens.

The National Weather Service presents this site on synoptic meteorology, large-scale weather systems. Learn about the structure and behavior of the atmosphere, including clouds, precipitation, winds and more. Also includes learning...

Find out how good your weather prediction skills are as you study the movements of air and water, and their interactions. Then predict what the spring holds for residents of different regions of the United States, and what people should...

Review the main types of weather fronts using this study guide.

Information on what weather is to begin with, then progresses to how scientists can predict the weather. Common ways to predict weather are also included such as use of a barometer and rain gauge.

No scientific phenomena concern us as much as the daily evolution of weather systems. We live in a culture where weather, the state of the atmosphere at a given time and place,helps us define regional cultural variations. States such as...
