wunder beta⛈️ How Storms Form
From a warm breeze to a roaring supercell: the science of how storms form.
What you’ll learn
- Explain how uneven heating, convection, and condensation build storm clouds.The Sun heats Earth unevenly, driving convection. Rising warm, moist air cools, condenses into clouds releasing latent heat, and can build into towering cumulonimbus thunderheads.
- Describe the life cycle of a thunderstorm and how lightning, hail, and wind shear work.Thunderstorms develop, mature, and dissipate over about thirty minutes. Charge separation causes lightning and thunder, updrafts grow hail, and wind shear lets storms last longer and rotate.
- Explain how supercells, tornadoes, and hurricanes form and how storms are forecast.Supercells have rotating updrafts that can spawn tornadoes when spinning air is tilted upright. Hurricanes form over warm tropical seas. Satellites, radar, and models help forecasters warn of severe weather.
Questions this course answers
What process describes warm, less dense air rising in the atmosphere?
Convection is the rising of warm, less dense air, and the resulting updraft is the engine of storm formation.
What happens as rising air cools to its dew point?
Cooling air reaches its dew point and water vapor condenses into droplets, forming clouds and releasing latent heat.
What is the towering cloud that produces thunderstorms called?
A cumulonimbus is the tall thunderstorm cloud, often reaching the top of the troposphere and spreading into an anvil.
What causes the sound of thunder?
Lightning superheats the air, which expands explosively and creates the sound wave we hear as thunder.
How do hailstones grow large inside a thunderstorm?
Powerful updrafts keep ice pellets aloft, and each rise and fall adds another layer of ice until they grow heavy and fall.
How does strong wind shear help a storm last longer?
Wind shear tilts the storm so the rain-cooled downdraft falls away from the updraft, letting the storm persist and even rotate.
