1Two things are going on
A calm center pulls air in — across a spinning floor
You only need two ideas. Watch each one:
A low spot pulls air inward
The middle of a storm is a calm, empty low spot. Air always pours from a crowded place toward an emptier one — so wind rushes inward toward the center from every side.
The ground is spinning
Earth turns all day long. So the floor the wind travels across is sliding too — and that slide gives a tiny sideways nudge to anything moving across it.
2Straight path vs bent path
A still floor vs a turning floor
Watch one wind arrow travel toward the center. The only thing that changes is whether the floor underneath is turning:
Goes straight
The ground holds still, so the wind keeps a dead-straight line — right at the center.
Curves to the side
The ground slides under the wind, so the same straight path quietly bends to one side.
3Your turn — pull the air in
Make the low spot suck air in harder
Here's the calm low center with air streaming in from all around. Drag the slider to make the pull stronger and the wind rush faster. The planet is holding still for now — watch where all that air ends up.
4Now switch Earth's spin on
Same rushing air — but now let the planet turn 🌍
So far the planet was frozen still and the air just piled straight into the middle. The big test: keep the air rushing in, then flip on Earth's spin and watch. Guess first — then turn it on.
Guess before you flip the switch
Air is rushing toward the storm's center from every side. Without Earth spinning, does it still make a swirl?
