11 wrz 2024 · Inside thunderclouds, warm, humid air rises, while cool air falls--along with rain or hail. These conditions can cause spinning air currents inside the cloud. Although the spinning currents start out horizontal, they can turn vertical and drop down from the cloud--becoming a tornado.
It is often thought that opening windows will lessen the damage caused by the tornado. While there is a large drop in atmospheric pressure inside a strong tornado, the pressure difference is unlikely to cause significant damage.

28 sie 2019 · What causes tornadoes? The most violent tornadoes come from supercells, large thunderstorms that have winds already in rotation.
The updraft of warm air causes the vortex to swell with water vapor, creating a spiraling funnel cloud at its center—the first visible sign that a tornado is brewing. The cool downdraft of air then battles the funnel cloud’s upward spiral, focusing the cloud into a smaller area and increasing its speed.
