1. What is Lapse Rate?

The lapse rate is the rate at which atmospheric temperature decreases with increasing altitude. It's a fundamental concept in meteorology and atmospheric science, helping to determine atmospheric stability and predict weather patterns.

2. How Does the Calculator Work?

The calculator uses the lapse rate formula:

Where:

• \( T1 \) — Temperature at height 1 (°C)
• \( T2 \) — Temperature at height 2 (°C)
• \( H1 \) — Height 1 (meters)
• \( H2 \) — Height 2 (meters)

Explanation: The equation calculates the temperature change per unit of vertical distance in the atmosphere.

3. Importance of Lapse Rate

Details: Lapse rate is crucial for understanding atmospheric stability, predicting cloud formation, and analyzing weather patterns. Different lapse rates indicate different atmospheric conditions.

4. Using the Calculator

Tips: Enter temperatures in °C and heights in meters. Ensure height difference (H2 - H1) is not zero. The result is expressed in °C per meter.

5. Frequently Asked Questions (FAQ)

Q1: What is the environmental lapse rate?
A: The actual observed rate of temperature decrease with altitude in the atmosphere, typically about 6.5°C per 1000 m.

Q2: What is the dry adiabatic lapse rate?
A: The rate at which dry air cools as it rises (9.8°C per 1000 m) or warms as it descends.

Q3: What does a negative lapse rate indicate?
A: A negative lapse rate means temperature increases with altitude, known as an inversion.

Q4: How does lapse rate affect weather?
A: It determines atmospheric stability - steep lapse rates promote vertical air movement and storm development.

Q5: What are typical lapse rate values?
A: Normally 6-10°C per 1000 m. Values significantly different indicate unusual atmospheric conditions.
