The effect of temperature increasing with height leads to a:

• A. Positive lapse rate
• B. Negative lapse rate
• C. Variable lapse rate
• D. Stable lapse rate

Answer: (B)

The scenario where temperature increases with height indicates a negative lapse rate. Typically, in the atmosphere, temperature decreases with elevation, which is termed a positive lapse rate. However, when the temperature increases, typically in situations such as temperature inversions, the atmosphere becomes stable. A negative lapse rate can suppress vertical mixing, making it difficult for air parcels to rise, as warmer air sits on top of cooler air. This stability can lead to a variety of weather phenomena, including fog and low-level clouds, as the lifting of air is inhibited. Therefore, understanding the nature of a negative lapse rate is crucial for predicting atmospheric stability and the potential for severe weather development. This context helps clarify the unique characteristics of a negative lapse rate, distinguishing its behavior in atmospheric phenomena.
