Why the question:
The question is from the static portions of GS paper I , part geography.
Key Demand of the question:
The answer must detail upon the concept of Air masses, their classification and their influence on the World Weather.
Discuss – This is an all-encompassing directive – you have to debate on paper by going through the details of the issues concerned by examining each one of them. You have to give reasons for both for and against arguments.
Structure of the answer:
Define what air masses are; the air with distinctive characteristics in terms of temperature and humidity is called an air mass. It is a large body of air having little horizontal variation in temperature and moisture.
The answer is pretty much straight forward and must cover the following dimensions –
- Chief characteristics of Air masses
- Classification of Air Masses – various types, their characteristics
- Influence of Air Masses on World Weather
Substantiate the above aspects with relevant diagrammatic demonstrations and explain their influence on World weather with suitable examples.
Conclude with importance of such a concept as a key deciding factor in carving the weather system of the World.
