Q. What is frontogenesis? Discuss the inversion of temperature across a front and its impact? 

Why the question:

The question is part of the static syllabus of General studies paper – 1 and mentioned as part of Mission-2022 Secure timetable.

Key Demand of the question:

To write frontogenesis, frontal inversion and its impact.

Directive word: 

Discuss – This is an all-encompassing directive – you must debate on paper by going through the details of the issues concerned by examining each one of them. You must give reasons for both for and against arguments.

Structure of the answer:


Define frontogenesis.


In the first part, write about the various causes/factors for frontogenesis – Horizontal divergence/difluence, Horizontal deformation, Vorticity, Tilting effects, Adiabatic heating etc.

Next, explain the process of frontal inversion. Use a small diagram for better representation.

Next, write about the impacts of frontal inversion – rainfall, visibility etc.


Conclude by summarising.
