What conditions cause winds and rotating storms?

Answer 1

Wind is caused by uneven heating and pressure differences. Air tends to move toward an area where warm air is rising and away from an area where cool air is sinking. Similarly, air is pulled towards low pressure and away from high pressure.. However, as a consequence of earth's spin, in large scale systems air moves to the right of the direction of pull in the northern hemisphere, and to the left in the Southern Hemisphere. This causes large scale weather systems to rotate. Large scale storm systems are low pressure systems. Smaller scale rotating storms, such as supercells and the tornadoes their produce get their rotation from wind shear, or differences in wind speed and direction at different heights.

Answer 2

Winds are primarily caused by differences in air pressure across regions, leading to air moving from high pressure to low pressure areas. Rotating storms, such as hurricanes and tornadoes, are caused by a combination of warm, moist air rising rapidly in the atmosphere and the Earth's rotation creating a spinning motion within the storm system. Other factors like temperature, humidity, and atmospheric instability also play a role in the development of rotating storms.
