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...

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...

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.

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...

Read and understand the differences between a cold and a warm front.

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.

Photos, diagrams, and other images related to weather.

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...

Learn all about wind, what it is, words used to describe wind, the different types, the coriolis effect, different types of breezes, and how wind is measured.

Students learn that buoyancy is responsible for making boats, hot air balloons and weather balloons float. They calculate whether or not a boat or balloon will float, and calculate the volume needed to make a balloon or boat of a certain...

The University of Oklahoma explores numerous types of weather and atmospheric changes, as well as the reasons behind them. Content details the four seasons, common meteorological variables, the vertical structure of the atmosphere, how...

This website provides information about weather.

Imagine our weather if Earth were completely motionless, had a flat dry landscape and an un-tilted axis. This, of course, is not the case; if it were, the weather would be much different. The local weather that impacts our daily lives...

Learners learn that wind and storms can form at the boundaries of interacting high and low pressure air masses. They learn the distinguishing features of the four main types of weather fronts (warm fronts, cold fronts, stationary fronts...

A collection of interactive concept models and active learning materials for teaching meteorology that illustrate conceptually difficult processes in atmospheric science. Active learning exercises are provided as guided instruction to...

Students learn about tornadoes - their basic characteristics, damage and occurrences. Students are introduced to the ways that engineers consider strong winds, specifically tornadoes, in their design of structures. Also, students learn...

A discussion from the Oklahoma Climatological Survey of the thermal factors effecting the movement of air masses in the atmosphere. Numerous topics such as methods of heat transfer, latent heat, phase changes (including sublimation and...

A great description of the global scale circulation and heat energy. Discusses a single-cell model, a three-cell model, jet streams and more.
