Moist air rises to the condensation level (altitude where temperature is below dew point.
- It’s cooled below dew point.
- Tiny water droplets condense around tiny particles such as dust, smoke particles and pollen grains and salt particles (condensation nuclei).
- The droplets merge and eventually become bigger and fall as rain.
- If moisture rises to an altitude where temperature is below 0?c the condensed water droplets freeze forming ice particles or super cooled water (water which has remained in a liquid state at temperatures below freezing point due to lack of sufficient condensation nuclei.
- Super cooled cloud droplets may mould themselves around ice crystals before freezing to form hail.
