1. What is Atmospheric Lapse Rate?

The atmospheric lapse rate describes how air temperature changes with altitude. The standard lapse rate is 6.5°C per kilometer, meaning temperature decreases by about 6.5 degrees for every kilometer you go up in the atmosphere.

2. How Does the Calculator Work?

The calculator uses the standard lapse rate equation:

Where:

• Base Temperature — Starting temperature at ground level (°C)
• 6.5 — Standard lapse rate (°C per km)
• Altitude — Height difference from ground (km)

Fun Fact: This is why mountains have snow on top even when it's warm at the bottom!

3. Why is Lapse Rate Important?

Details: Understanding lapse rate helps explain weather patterns, cloud formation, and why different altitudes have different ecosystems.

4. Using the Calculator

Tips: Enter the ground temperature and how high you want to go. The calculator will tell you how cold it would be at that altitude!

5. Frequently Asked Questions (FAQ)

Q1: Is the lapse rate always 6.5°C/km?
A: No, this is just the average. It can change depending on weather conditions.

Q2: Why does temperature decrease with altitude?
A: Because air pressure decreases, and the air expands and cools as it rises.

Q3: Does this work for really high altitudes?
A: The standard lapse rate works best for the lower atmosphere (troposphere).

Q4: Can I use this to predict mountain temperatures?
A: Yes! Try entering your hometown's temperature and the height of a nearby mountain.

Q5: Why is this important for pilots?
A: Pilots need to know about temperature changes to predict icing conditions.
