Why do Hurricanes occur?

Question

We all know that there's a purpose for natural things happening in life for example the water cycle helps cool the earth and give plants and trees water and therefore life.

But hurricanes just seems to cause utter destruction and anarchy for us humans, animals and plant life.

What do you think the purpose of hurricanes is?

Answer 1

Hurricanes are the natural result of a specific set of conditions, which include warm water, the Coriolis Effect, and low wind shear.

If you want to view it as some "greater purpose" then you could say that they serve to balance the great equation that results in every weather event in the atmosphere.

If you are looking for some religious explanation, then I leave you to figure that out.

Answer 2

Hurricanes are one of the many ways nature tries to restore energy balance between the surface and the atmosphere.  During the summer months the Sun beats down on the tropical waters and a lot of solar energy is absorbed and stored in those waters, heating them up.  A hurricane is essentially a massive heat engine that transfers that excessive heat energy from the waters and the adjacent warm moist air upward into the atmosphere by condensing massive amounts of water vapor.  Unfortunately as it does so, the heat is released mostly in the core, which in turn lowers the pressure and accelerates the wind around the core (the eye of the storm).  It is a necessary, though sometimes quite destructive, process.
