Q. How are air masses classified? Explain the process of formation of air masses? What is the impact of air mases on weather across the world?
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 about the classification, process of formation and the impact of air masses in weather.
Explain – Clarify the topic by giving a detailed account as to how and why it occurred, or what is the context. You must be defining key terms wherever appropriate and substantiate with relevant associated facts.
Structure of the answer:
Define what air masses are and the chief characteristics of Air masses.
First, bring out the classification of Air Masses – various types, their characteristics.
Next, write about the processes behind the formation of air masses – essential conditions for formation of an air mass such as uniformity in meteorological conditions, ample time and plain topography which plays an assisting role.
Next, explain how air masses impact the micro climate – creation of an occluded front, maritime air masses causing rainfall, cyclonic and anti-cyclonic conditions etc. Give examples for these impacts on micro climate.
Summarise the major impacts air masses.
