How clouds are formed
• Orographic lifting occurs when air is forced upward by a barrier of mountains or hills.

• Convective lifting occurs when air heated at the earth's surface rises in the form of thermal currents or bubbles.

• Widespread ascent results from the interaction of air masses, or the movement of a cold air mass forcing warm air to rise ahead of it.

How clouds are formed
• Mechanical (or frictional) turbulence occurs when the air flow is deformed into a series of eddies as it moves over the earth's surface.
