Cloud Base Calculator

Calculate the cloud base height based on surface temperature and dew point temperature using the Lifting Condensation Level (LCL) method.

Input Parameters

Calculation Results

Calculation Formula

Cloud Base Height (LCL) = 125 × (T - Td)

Where:
T = Surface Temperature (°C)
Td = Dew Point Temperature (°C)
LCL = Lifting Condensation Level (meters)

Result

Cloud Base Height: -- meters

Note: This calculation assumes standard atmospheric conditions.

Cloud Base Calculator Usage Guide

Learn how to use the Cloud Base Calculator and understand its working principles.

How to Use This Calculator

  1. Enter the surface temperature in degrees Celsius (°C). This is the actual temperature at ground level.
  2. Enter the dew point temperature in degrees Celsius (°C). This is the temperature at which air becomes saturated and water vapor begins to condense.
  3. Click the "Calculate" button to determine the cloud base height.
  4. The result will be displayed in meters, representing the height at which clouds typically form under standard atmospheric conditions.

Understanding the Calculation

This calculator uses the Lifting Condensation Level (LCL) formula, which estimates the height at which moist air will reach saturation and begin to form clouds when lifted adiabatically.

The formula used is:

LCL = 125 × (T - Td)

Where:

  • LCL = Lifting Condensation Level (meters)
  • T = Surface Temperature (°C)
  • Td = Dew Point Temperature (°C)

Practical Applications

This calculator is useful for:

  • Astronomy enthusiasts who want to know when the sky might clear for star gazing
  • Weather enthusiasts who want to understand cloud formation
  • Aviation professionals who need to assess potential turbulence from cloud base height
  • Hobbyists interested in meteorology and cloud observation

Note: This calculation assumes standard atmospheric conditions. Actual cloud base height can vary based on local atmospheric pressure, humidity profiles, and other factors.
