how winds and storms are formed
Answers
Answer:
The storms occur when high levels of condensation form in a volume of unstable air that generates deep, rapid, upward motion in the atmosphere. The heat energy creates powerful rising air currents that swirl upwards to the tropopause. Cool descending air currents produce strong downdraughts below the storm.

Explanation:
how storms are formed
A storm is defined as a wind of force 10 in the Beaufort scale. That is formed by a very strong convection (rising) of the air, and its resulting lower pressure.
If you draw, on a map, lines of equal pressure, what is called, isobars, then the tighter they are together, the more wind there will be. An old sailor’s saying is that, a pressure that falls or rises by ten millibars in a period of 8 hours, is a sure sign that a gale wind is on its way.
how winds are formed
If you blow in a straw, a wind will be created because of a difference of pressure between your mouth and the atmosphere.
Likewise, the wind is created between a difference of pressure in the air. As warm air rises somewhere, it lowers the pressure. As cold air sinks somewhere else, it increases the pressure. The air will then flow from high to low pressure. This is called, the gradient force.
In the northern hemisphere, due to the Coriolis effect, it then spins counter-clockwise to create what we call, the geostrophic wind; what we feel as the wind caused by bad weather.
