Topic – Part of static series under the heading “Fronts”
6) Explain the role of the polar front and the air masses that come in conflict in the polar front zone in the temperature and precipitation cycles of the mid latitude and high latitude climates?(250 words)
Key demand of the question
The question expects us to explain in brief what polar fronts are and the role they play in influencing the temperature of precipitation cycle of the upper and mid latitude regions.
Structure of the answer
Introduction – Explain Polar front is an area where cold polar winds meet hot tropical air masses. Temperature of these two air masses is very different and leads to formation of stationary front. Explain that it is basically an occluded front.
Body – Discuss the impact of such fronts on temperature and rainfall in the region. Pictorial explanations will fetch you more marks. The approach of the cyclone is marked by fall in temperature and light drizzle. When warm front approaches temperature rises and rainfall stops.Arrival of Cold front again leads to fall in temperature and heavy rainfall with thunder. Explain the mechanism of such changes in detail.
