Air Masses and Fronts
An air mass will usually remain fairly uniform while it travels across an area and bring with it the weather from its source location. Often, when air masses collide, frontal boundaries are created which create many of the severe weather systems we encounter.
Air pressure will often indicate coming weather conditions by signaling when a low or high pressure system is moving through an area. Here, the instruments and techniques used in forecasting are discussed so you can learn to understand the types of weather a low or high pressure system will bring.

Understanding climate is essential for a multitude of reasons. For instance, climatologists need to understand past weather in order to develop accurate diagrams and data about climate change. Even a local gardener or farmer must understand climate zones and regional climate. In yet another example, global warming data is collected by gathering climate variables over time.
Clouds are familiar to all of us. We look up into the sky and often dream of the funny shapes clouds can seem to take on. We know dark clouds bring storms and clear skies are a sign of good weather, but what about the different types of clouds? There is more to discovering clouds than you thought! Explore cloud formations and discover how to make your own clouds in this guided lesson.

The Ozone Layer
Check the problems with ozone as you read how to protect this precious resource. Although problems with ozone have appeared to improve in the last several years, we are not out of the danger zone yet. Learn what you can do to help and learn the current status of the ozone hole over the Antarctic.
We all know about rain, snow, sleet, and hail, but there is so much more to precipitation than just the liquids and solids we see falling from the sky. Find information on the latest developments in precipitation forecasting including links to severe storm information.

Whether it is warm or cool, hot or cold, the temperature is usually the first aspect of weather we prepare for in a day. Just getting dressed in the morning will usually involve a check of your local weather channel. Temperatures can actually be dangerous. With extreme heat and cold, lives can be at stake. Here, learn how to read thermometers, temperature maps, and heat index charts to explore this exciting meteorology topic.
