Lapse rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

Lapse Rate = Change in Temperature/Altitude difference
λ = ∆T/Δh
This formula uses 3 Variables

Variables Used

Lapse Rate - (Measured in Kelvin Per Meter) - The Lapse rate is the rate at which temperature changes with height in the atmosphere.
Change in Temperature - (Measured in Kelvin) - The Change in Temperature is the difference between the initial and final temperature.
Altitude difference - (Measured in Meter) - Altitude difference is the difference or change in altitude.

STEP 1: Convert Input(s) to Base Unit

Change in Temperature: 3.5 Kelvin --> 3.5 Kelvin No Conversion Required
Altitude difference: 5 Meter --> 5 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

λ = ∆T/Δh --> 3.5/5

Evaluating ... ...

λ = 0.7

STEP 3: Convert Result to Output's Unit

0.7 Kelvin Per Meter --> No Conversion Required

FINAL ANSWER

0.7 Kelvin Per Meter <-- Lapse Rate

Geometric altitude for given geopotential altitude

LaTeX Go Geometric Altitude = [Earth-R]*Geopotential altitude/([Earth-R]-Geopotential altitude)

Geopotential altitude

LaTeX Go Geopotential altitude = [Earth-R]*Geometric Altitude/([Earth-R]+Geometric Altitude)

Geometric altitude

LaTeX Go Geometric Altitude = Absolute Altitude-[Earth-R]

Absolute altitude

LaTeX Go Absolute Altitude = Geometric Altitude+[Earth-R]

Lapse rate Formula

What is environmental lapse rate?

The environmental lapse rate (ELR), is the rate of decrease of temperature with altitude in the stationary atmosphere at a given time and location.

How to Calculate Lapse rate?

Lapse rate calculator uses Lapse Rate = Change in Temperature/Altitude difference to calculate the Lapse Rate, Lapse Rate is a measure of the rate of decrease in temperature with an increase in altitude, typically expressed as a ratio of the change in temperature to the altitude difference. Lapse Rate is denoted by λ symbol.

How to calculate Lapse rate using this online calculator? To use this online calculator for Lapse rate, enter Change in Temperature (∆T) & Altitude difference (Δh) and hit the calculate button. Here is how the Lapse rate calculation can be explained with given input values -> 10 = 3.5/5.

FAQ

What is Lapse rate?

Lapse Rate is a measure of the rate of decrease in temperature with an increase in altitude, typically expressed as a ratio of the change in temperature to the altitude difference and is represented as λ = ∆T/Δh or Lapse Rate = Change in Temperature/Altitude difference. The Change in Temperature is the difference between the initial and final temperature & Altitude difference is the difference or change in altitude.

How to calculate Lapse rate?

Lapse Rate is a measure of the rate of decrease in temperature with an increase in altitude, typically expressed as a ratio of the change in temperature to the altitude difference is calculated using Lapse Rate = Change in Temperature/Altitude difference. To calculate Lapse rate, you need Change in Temperature (∆T) & Altitude difference (Δh). With our tool, you need to enter the respective value for Change in Temperature & Altitude difference and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
