Answer: 

Introduction:

Temperature inversion is a meteorological phenomenon where the normal decrease in temperature with height is reversed, and the temperature increases instead of decreasing. In other words, the air near the surface of the Earth is cooler than the air above it.

Body:

Temperature inversion can occur due to several factors such as radiation cooling, subsidence of air, advection of warm air, and the presence of an inversion layer.

Significant effects on weather and environment:

• Air pollution: Temperature inversion can trap pollutants in the lower atmosphere and cause smog and poor air quality, leading to respiratory problems.
• Fog: Temperature inversion can lead to the formation of fog and low clouds due to the cooling of moist air near the surface. According to an IQAIR report Delhi will rank 4th position in the world in 2022.
• Temperature: Temperature inversion can cause significant temperature differences in the air at different altitudes, which can affect temperature-sensitive crops and cause damage.
• Flight Disruptions: Temperature inversion can cause turbulence and affect aircraft operations due to the difference in temperature and pressure.
• Delay in Weather Events: Temperature inversion can delay or prevent the formation of thunderstorms, leading to drought conditions.

Conclusion:

Temperature inversion is a complex meteorological phenomenon that can have serious impacts on the environment and the people living in an area. Its effects can range from air pollution to extreme weather conditions and can be challenging to predict and manage. Therefore, it is essential to understand temperature inversion and its impacts to ensure better preparedness and management of its effects.
