the word 'hurricane' - air

The word 'Hurricane' is the name given to nature's strongest storm.
A hurricane occurs when high pressure
and low pressure masses of air come in contact with one another.
There is often a significant difference in temperature
between the two masses.
One mass is warm, while the other is cold.
The warmer air rises, and the cooler air falls.
Likewise, the low pressure area slides
down the sides of the high pressure area.
They swirl in and around one another,
creating the beginnings of the storm
