High Altitude Temperature Equation:
| From: | To: |
The High Altitude Temperature Equation estimates temperature at a given altitude based on sea level temperature and the environmental lapse rate. This calculation is important in meteorology, aviation, and environmental science.
The calculator uses the altitude temperature equation:
Where:
Explanation: The equation calculates how temperature decreases with increasing altitude based on the standard environmental lapse rate.
Details: Accurate temperature estimation at different altitudes is crucial for weather forecasting, flight planning, mountain climbing preparation, and understanding atmospheric conditions.
Tips: Enter sea level temperature in °C, lapse rate in °C/km (standard is 6.5°C/km), and altitude in kilometers. Altitude must be a non-negative value.
Q1: What is the standard environmental lapse rate?
A: The standard environmental lapse rate is approximately 6.5°C per kilometer in the troposphere.
Q2: Does this equation work for all altitudes?
A: This equation provides a good approximation for altitudes within the troposphere (up to about 11 km). Different lapse rates may apply in other atmospheric layers.
Q3: Why does temperature decrease with altitude?
A: Temperature decreases with altitude because atmospheric pressure decreases, causing air to expand and cool adiabatically.
Q4: Are there situations where the lapse rate differs?
A: Yes, lapse rates can vary due to weather conditions, humidity, and geographical location. Inversions can even cause temperature to increase with altitude.
Q5: Can this be used for very high altitudes?
A: For altitudes above the troposphere, different temperature profiles apply, and this simple linear equation may not be accurate.
