METEOROLOGY – WIND CALCULATOR
Land Breeze Speed
A precise tool.
What is the Land Breeze Speed & How does it work?
A land breeze is a wind that blows from the land towards the sea, typically occurring at night when the land cools more rapidly than the adjacent water. This temperature difference creates a pressure gradient, driving air from the cooler land to the warmer water.
The formula accounts for the gravitational acceleration (g), the difference in temperatures between land and water, the height above sea level, and the latent heat of vaporization. This helps in calculating the speed at which the land breeze moves.
v = sqrt{frac{2g(T_s – T_w)h}{L}}
v = wind speed, T_s = surface temperature of the land, T_w = surface temperature of the water, h = height above sea level, L = latent heat of vaporization
The formula accounts for the gravitational acceleration (g), the difference in temperatures between land and water, the height above sea level, and the latent heat of vaporization. This helps in calculating the speed at which the land breeze moves.

Frequently Asked Questions
What is a land breeze?
A land breeze is a wind that blows from the land towards the sea at night when the land cools more rapidly than the adjacent water.
How does the formula for land breeze speed work?
The formula accounts for gravitational acceleration, temperature differences between land and water, height above sea level, and latent heat of vaporization to calculate wind speed.
What variables are needed to calculate land breeze speed?
You need the surface temperature of the land (T_s), surface temperature of the water (T_w), height above sea level (h), and the latent heat of vaporization (L).
When does a land breeze typically occur?
A land breeze typically occurs at night when the land cools more rapidly than the adjacent water.
Why is the height above sea level important in this calculation?
Height above sea level affects how air pressure changes with temperature, influencing the wind speed calculation.
What does latent heat of vaporization represent in this formula?
Latent heat of vaporization represents the energy required to change water from a liquid to a gas without changing its temperature.
How can I use this calculator to find out if there will be a land breeze tonight?
Input the current surface temperatures of your area’s land and sea, your elevation above sea level, and the latent heat of vaporization into the formula to estimate wind speed.
