Where are tropical storms found?
They are generally found in the tropics. The hurricanes are found around America off the Pacific Ocean, cyclones and typhoons are found in parts of Asia around the Indian Ocean.

- central pressure
The bigger the difference in pressure, the stronger the winds. The wind travels from high to low pressure. They often knock out power and key communication lines.
