Hurricane PSA

By Bethany & savannah

How it forms

A hurricane will start out as a tropical disturbance(warm water with building rain clouds). From that it will grow into a tropical depression(rotating thunderstorms with winds of 38mph or less). With just one more higher speed it will be a tropical storm when winds reach 39mph. It will finally be a hurricane if wind reaches 74 mph.

Characteristics of a hurricane/structure

Characteristics:

- formed over tropical oceans

- have rotary circulation

- also called typhoons


Structure:

Eye: center of the storm

- all rain precipitation ceases

Eye wall: 10-20km from center

- greatest winds & heaviest rains

Spiral Rainbands:

Bands of heavy convective showers that spiral inward toward the storms center


More about structure...

Hurricanes are formed from large numbers of thunderstorms arranged in pinwheel formation.

Below~7.5km:

Inward of spiraling motion around low pressure

Above~7.5km:

Cirrus clouds spiral outward around high pressure center.
