How does temperature inversion affect atmospheric conditions and what are the implications for local weather patterns and air pollution levels? (Answer in 250 words) 15 Marks
Introduction
Temperature inversion is the phenomenon when temperature of the atmosphere upper to surface is colder than heat away from the surface.

Main Body
Definition with example: normal cooling vs comparing to ordinary cope stable, normal cloud cover, long nights, cold nights. Impact of temperature inversion on atmospheric conditions: 1) O2 in lower atmosphere, 2) Golden layer near the temperature inversion (deadly), 3) Air in ground, plants, etc. 4) In himalayan area, the dew drops freeze leading to crop loss.
Warm effect as heat field dumpishes, no cold field dumpishes. High (conductive cooling) and low (trial radiative heating) of low atmosphere. Potential anti-cycline conditions in pressure reversal. Implications: High pressure formation and outflow of air from temperature inversion area. Accumulation of pollutants and smog formation. Haze chemical formation over industrial volatile organic compounds. Low visibility especially in mountains.
Conclusion
Health impacts: respiratory issues due to pollution concentration, frost bites due to freezing. Effects most prominent in mountain valleys. Note: This national identity is still relevant for India.
