  • Collision coalescence process is an important mechanism in formation of raindrops in warmer clouds or we can say whose temperature do not extend beyond the freezing level.
  • This phenomenon cannot occur in cirrocumulus clouds because they are made up of ice crystals and supercooled water.

Collision-coalescence process of precipitation

The collision-coalescence process of precipitation involves the merging of smaller cloud droplets into larger droplets until they become heavy enough to fall as precipitation. This process is more common in warmer clouds.

Applicability to clouds

Clouds which do not extend beyond the freezing level
In the collision-coalescence process, the presence of supercooled water droplets (liquid water below freezing temperature) is essential for the coalescence to occur. Clouds that do not extend beyond the freezing level typically consist of supercooled water droplets, which can collide and merge to form precipitation.

Clouds which extend beyond the freezing level
In clouds that extend beyond the freezing level, other processes such as the ice crystal process or the Bergeron process may dominate over the collision-coalescence process. These processes involve the formation of ice crystals and snowflakes, which can grow and eventually fall as precipitation.

Conclusion

Therefore, the collision-coalescence process of precipitation is applicable to clouds that do not extend beyond the freezing level, where the presence of supercooled water droplets allows for the merging of cloud droplets to form precipitation.

Read the following passage carefully and choose the most appropriate answer to the question out of the four alternatives.The water cycle — technically known as the hydrological cycle — is the continuous circulation of water within the Earths hydrosphere, and is driven by solar radiation. This includes the atmosphere, land, surface water and groundwater. As water moves through the cycle, it changes state between liquid, solid, and gas phases. Water moves from compartment to compartment, such as from river to ocean, by the physical processes of evaporation, precipitation, infiltration, runoff, and subsurface flow. Movement of water within the water cycle is the subject of the field of hydrology. The water cycle is the process that all water takes. It includes precipitation which isthe falling of water in any form on Earth, infiltration which is the process in which water is absorbed into the soil (it may also flow off the surface called surface runoff) evaporation or transpiration which is either when water is heated and turns into water vapour or when plants use water and give it off as water vapour, condensation which is when the water vapour cools and forms clouds. This process is then repeated over and over again.Q. The study of the movement of water within the water cycle is known as
