        • Rain experienced on the windward slopes of mountains or hills,formed when moist air is forced to rise over a mountain or hill.
        • Air cools due to decreased temperature and decreased pressure causing it to expand.
        • Moisture condenses forming tiny water droplets (clouds).
        • The tiny water droplets in clouds merge and become too heavy to be suspended in air and fall as rain.
        • Rainfall is received on the windward side while the lee-ward side remains dry.
