Why Do Some Clouds Produce Rain While Others Do Not?

为什么有些云会下雨,有些却不会?

  1. Clouds form when water vapor cools and turns into tiny droplets.
  2. Rain falls only when these droplets grow heavy enough to fall.
  3. Wind, temperature, and air pressure all affect cloud behavior.
  4. Warm air holds more moisture than cold air does.
  5. Tiny dust particles help water droplets gather and grow larger.
  6. That is why some clouds rain and others stay dry.
