Q8.What do you understand by the phenomenon of temperature inversion in meteorology? How does it affect the weather and the inhabitants of the place?
5 marks
Introduction
Temperature inversion is a meteorological phenomenon where atmospheric temperature increases with increasing altitude, reversing the normal lapse rate. This occurs when a layer of cold, dense air is trapped beneath warmer, lighter air, creating highly stable atmospheric conditions.
Mechanism
This stability prevents vertical air mixing, leading to stagnant air near the surface. Common types include radiation inversion (ground inversion) on clear nights and valley inversion, where cold air drains into topographical depressions.
Effects
On Weather
- Pollutant trapping: Accumulates smoke, dust, and industrial emissions near the ground, leading to smog formation.
- Reduced visibility: Contributes to dense fog and haze, impacting transportation and daily life.
On Inhabitants
- Respiratory health issues: Concentrated airborne pollutants cause or worsen conditions like asthma and bronchitis.
- General health impact: Leads to eye irritation, headaches, and overall reduced well-being.
