Frontal precipitation comes under which type of precipitation?

Frontal precipitation comes under which type of precipitation? Correct Answer Cyclonic precipitation

Explanation:

On the basis of origin, rainfall may be classified into three main types – the Convectional, Orographic or relief and Cyclonic or Frontal.
1. Convectional Rainfall:

  • The air being heated becomes light and rises up in convection currents.
  • As it rises, it expands and loses heat and consequently, condensation takes place and cumulus clouds are formed.
  • Convectional precipitation is heavy but of short duration, highly localized, and is associated with a minimum amount of cloudiness.
  • It occurs mainly during summer and is common over equatorial doldrums in the Congo Basin, the Amazon basin, and the islands of south-east Asia.

2. Orographic Rainfall:

  • This type of precipitation occurs when warm, humid air strikes an Orographic barrier (a mountain range) head-on.
  • Due to the initial momentum, the air is forced to rise. As the moisture-laden air gains height, condensation sets in, and soon saturation point is reached.
  • The surplus moisture falls down as Orographic rainfall along the windward slopes.

3. Frontal or Cyclonic Rainfall:

  • When two air masses with different temperatures meet, turbulent conditions are produced.
  • Along the front convection takes place and causes precipitation. 
  • For instance, in northwest Europe, cold continental air and warm oceanic air converge to produce heavy rainfall in adjacent areas.
  • Cyclonic Rainfall is convectional rainfall on a large scale.
  • The precipitation in a tropical cyclone is of convectional type while that in a temperate cyclone is because of frontal activity.
