A hurricane uses that same idea, but supercharged by ocean heat. Warm ocean water evaporates into the air above it. As that water vapor rises and cools, it condenses back into droplets, and this releases a burst of heat called latent heat. That heat warms the air even more, so it rises faster, pulling in more moist air from below. Earth's rotation bends that inward rush into a spiral, and the whole system organizes itself around a center of very low pressure. *(drawing: Warm water evaporates, rises, and releases heat as it condenses. That extra heat powers the spin.)* Tornadoes form in a very different setting: inside a supercell, a thunderstorm that rotates. Winds blowing at different speeds and directions at different heights, something called wind shear, tip a spinning tube of air from horizontal to vertical. The storm's updraft then stretches and tightens that spinning air into a narrow funnel. When the funnel reaches the ground, it's a tornado. A hurricane can take days to build over hundreds of miles of ocean, while a tornado can form in minutes and touch down over just a few streets. Monsoons work on the same land-versus-sea heating you saw with wind belts, just on a seasonal scale. In summer, land heats up faster than the ocean next to it. The hot air over land rises, and moist ocean air rushes in to replace it, bringing heavy monsoon rains. In winter, the pattern flips: land cools faster than the ocean, so the wind reverses and blows from the cooler land back out toward the warmer sea, giving a dry season. **Tip.** When a big storm hits, scientists now ask a sharper question: how much did climate change have to do with it? To find out, they run a computer climate model twice for the same storm, once using today's warmer climate and once using a version of the world without the extra heat-trapping gases people have added. Comparing the two runs tells them how much more likely or how much stronger the storm became because of climate change. This is called attribution science. **Recap.** Hurricanes grow from ocean heat, tornadoes twist out of rotating thunderstorms, monsoons flip with the seasons, and attribution science compares two versions of the world to measure climate change's fingerprint on one storm. ## Practice 8 questions on this page, each with its working shown. ## Needs first - [Reading Weather Maps](https://lightmysky.com/learn/science/reading-weather-maps-mt_3pgTpuetKi) - [Extreme Weather Events](https://lightmysky.com/learn/science/extreme-weather-events-mt_6EfevRyeFW) - [Global Wind Patterns](https://lightmysky.com/learn/science/global-wind-patterns-mt_iYOcfzFqMw) - [Reading Ancient Climate Records](https://lightmysky.com/learn/science/reading-ancient-climate-records-mt_olFzbawexJ) ## Opens up - [Global Circulation: Cells, Jets and Why Deserts Sit Where They Do](https://lightmysky.com/learn/science/global-circulation-cells-jets-and-why-deserts-sit-where-they-do-mt_nHAXncXpaS)
