Winter Weather

Identify what is black ice and understand how this clear glaze forms on roads during sub-zero temperatures to stay safe.

Learn what is graupel and how riming creates these unique snow pellets. Distinguish between hail, sleet, and frozen precipitation during winter storms.

Explore the physics of lake-effect snow and how cold air over warm water produces intense localized squalls.

Learn how a snow squall causes sudden whiteout conditions and flash freezes on highways.

Learn how do ice storms form when supercooled water droplets strike frozen surfaces during a thermal inversion.

How do avalanches form when snow layers fail under stress? Explore the mechanics of slab failure and mountain weather triggers to stay safe.

How do blizzards form through cyclogenesis and pressure gradients? Study the specific wind and visibility criteria that define these winter storms.
