Question

What's the difference between "storm and cyclone'"?

Answer 1

As air rises, it creates a lower pressure. It is called a convection. It can happen because the earth surface is warmed up by the sun, because a front between temperate and polar air pulls it up, or because mountains push the air up.

Depending on how much temperature difference there is between the surface and the upper atmosphere, that convection will increase, deepening the low pressure, until it creates winds of a strength that is called a storm.

Any form of low pressure can be called a cyclone, just as high pressures are called anti-cyclones.

When is it called a storm, a hurricane, a thyphoon or a cyclone? Those are simply a question of language and regions. Hurricane is the name for tropical convections born over the Atlantic and moving toward the US. Thyphoons and cyclones are names used for South-East Asia. Storms are what we call it in Europe. But they are all coming from the same reason: A convection creating a very deep low pressure. It results in strong winds (the low pressure tries to fill with air from surrounding higher pressures, and rain (rising air cools down and condense the air humitidy).

Answer 2

Storm is a generic term for bad weather formations.  The term 'Cyclone' is essentially the same as a Hurricane or Typhoon and the naming depends on what part of the world the formation takes place and whether it appears on a certain side of the dateline.
