26-Nov-2018 - Question 2

Discuss as to how frontogenesis contributes to weather instability.

For Question 1 - Click Here

Frontogenesis refers to the creation of fronts or regeneration of decaying fronts due to the convergence of two contrasting air masses.

Since fronts are formed due to the convergence of air masses of contrasting temperature and hence contrasting weather conditions there are differences experienced at the front in terms of temperature, humidity, precipitation, cloudiness and wind direction.

At the warm front, warm air is active and invades at the cold air zone and being lighter is lifted gradually and is cooled adiabatically from below. The cooling of warm air causes condensation and cloud formation followed by precipitation. This weather instability is of long duration. The sequence of clods from above downwards comprises cirrus, cirrostratus, altostratus and nimbostratus.



At the cold front, the cold and dense air becomes active and invades the warm air region and pushes it up aggressively. This leads to the formation of cumulonimbus clouds and heavy precipitation of short duration due to sudden cooling of the uplifted warm air from below.


Thus, frontogenesis contributed to weather instability.
