Clouds are the sky’s way of telling you what’s coming next, and once you know the basic categories, you can often predict weather changes hours before they arrive. The Three Height Families Meteorologists classify clouds primarily by altitude: high clouds (above roughly 20,000 ft), mid-level clouds (6,500-20,000 ft), and low clouds (below 6,500 ft), plus…

Thunderstorms form when three ingredients come together: moisture, rising warm air, and instability in the atmosphere. Understanding this recipe explains why storms tend to erupt on hot, humid afternoons and why some regions see far more of them than others. The Three Key Ingredients Moisture: Water vapor near the surface, often pulled in from oceans,…

Lightning is one of nature’s most dramatic displays, but at its core it’s a simple physics problem: how does a storm build up enough electrical charge to arc through the sky or strike the ground? Building an Electrical Charge Inside a thunderstorm, powerful updrafts and downdrafts send ice crystals, graupel (soft hail), and water droplets…
