Creating and Understanding Weather Fronts

The video tutorial from the weather channel explains the concept of weather fronts, focusing on cold and warm fronts. It describes how cold fronts are the boundary between two air masses, with cold air sinking below warm air due to its higher density. To visualize this, an experiment using colored water is demonstrated, showing how cold and warm water interact similarly to air masses in the atmosphere. The tutorial concludes by relating the experiment to real-world atmospheric conditions.

What do cold fronts bring in?

• Warm air

• Cold air

• Snow

• Rain
