Which one of the following conditions is suitable for inversion of temperature?

Correct option is B

Introduction
A Temperature Inversion (or thermal inversion) occurs when a layer of cold air near the ground is trapped beneath a layer of warmer air. The most ideal and common conditions for a strong radiation inversion are:
· Long winter night: Allows for maximum cooling of the ground through terrestrial radiation.
· Clear sky: Allows maximum terrestrial radiation to escape into space, cooling the surface further.
· Calm air: Prevents the mixing of the air layers, allowing the cold air to remain near the surface.
Information Booster
· Phenomenon: A reversal of the normal temperature profile, where temperature increases with altitude.
· Ideal Conditions: Long winter night, clear sky, and calm air.
· Long Night: Maximizes the time for the ground to lose heat through long-wave radiation.
· Clear Sky: Absence of clouds prevents them from trapping heat radiated from the ground.
· Calm Air: Prevents turbulent mixing of the air, ensuring the coldest air remains concentrated near the surface.
· Significance: Traps smoke and pollutants near the ground, leading to poor air quality.
Additional Points
· Clear sky and calm air: While necessary, these are often insufficient unless combined with a long night to maximize cooling.
· Long winter night and clear sky and Long winter night and calm air: These are partial sets of conditions; all three factors (long winter night, clear sky, and calm air) are required for the development of a strong surface radiation inversion.
