Question

Describe the concept of air mass and explain it's role in macro-climatic changes

Answer 1

Answer:

Role in macro climatic changes:-

When winds move air masses, they carry their weather conditions (heat or cold, dry or moist) from the source region to a new region. When the air mass reaches a new region, it might clash with another air mass that has a different temperature and humidity.

⏩Key demand of the question

The question expects us to answer by explaining what air masses are, essential conditions for the formation of an air mass, and how an air mass differed from a mass of air. Finally, explain how air masses impact the micro-climate of a region.

⏩Structure of the answer

Introduction – Explain that an air mass is a large body of air having uniform temperature, humidity and pressure which it adapts from the surface present below it. Discuss the essential conditions for formation of an air mass such as uniformity in meteorological conditions , ample time and plain topography which plays an assisting role.

Body – 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.
