1575 - What is the structure of a typhoon with a spiral cloud band and lowest central air pressure?
Imagine a big rotating storm in the ocean, that's a typhoon. Here's its main parts:
- Eye: The calm center of the storm, like a big empty circle. It's where the air is sinking, and it's the quietest and safest part.
- Spiral Cloud Band (or Spiral Rainband): This is the part that looks like a big, curly snake. It's where the rain and strong winds are. The storms in the band spiral into the center of the typhoon.
- Wall Cloud: This is the area around the eye where the clouds are really tall and puffy. It's where the winds are the strongest.
As for the lowest central air pressure: in the middle of the typhoon's eye, the air pressure is really, really low. That's because all the warm air rises and creates a big hole in the atmosphere. This low air pressure is what makes the storm strong and spiral.
Think of it like a super-powerful vacuum cleaner in the sky!
