Calculate Cloud Base Altitude (H)



Formula

The formula to calculate the cloud base altitude (H) is:

\[ H = \left(\frac{T - T_d}{4.4}\right) \times 1000 \]

Where:

Example

Let's say the surface temperature (\( T \)) is 25°C, and the dew point temperature (\( T_d \)) is 15°C. Using the formula:

\[ H = \left(\frac{25 - 15}{4.4}\right) \times 1000 \]

We get:

\[ H \approx 2272.73 \text{ feet} \]

So, the cloud base altitude (\( H \)) is approximately 2272.73 feet.

What is Cloud Base Altitude?

Cloud base altitude is the height above ground level at which the base of a cloud is located. It is an important parameter in meteorology and aviation as it indicates the altitude at which clouds begin to form. The cloud base altitude can be estimated using the surface temperature and the dew point temperature. When the air temperature cools to the dew point temperature, condensation occurs, leading to cloud formation. This altitude is crucial for pilots to ensure safe flight operations and for meteorologists to understand weather patterns.
