METEOROLOGY – PRECIPITATION CALCULATOR
Snowdrift Height
A precise tool.
What is the Snowdrift Height & How does it work?
Snowdrift height is influenced by the wind speed and the distance over which the wind blows snow, known as fetch. The higher the wind speed and the longer the fetch, the taller the snowdrift will be.
The formula to calculate the maximum height of a snowdrift is given by:
H = frac{v^2}{2g} cdot lnleft(frac{4f}{v}right)
H = height of snowdrift, v = wind speed, f = fetch, g = acceleration due to gravity (9.81 m/s²)
This formula assumes steady-state conditions and neglects factors such as snow density and temperature variations.

Frequently Asked Questions
What is the formula for calculating snowdrift height?
The formula is H = (v^2 / 2g) * ln(4f/v), where H is height, v is wind speed, f is fetch, and g is acceleration due to gravity.
How does wind speed affect snowdrift height?
Higher wind speeds result in taller snowdrifts because more force is applied to the snow.
What role does fetch play in snowdrift formation?
Fetch, or the distance over which the wind blows snow, determines how far the drift can extend and thus its height.
Can this formula be used for any type of snow?
This formula assumes steady-state conditions and neglects factors such as snow density and temperature.
What is the value of g in the snowdrift height formula?
The acceleration due to gravity (g) in the formula is 9.81 m/s².
How accurate is this calculator for real-world scenarios?
While useful, the calculator assumes ideal conditions and may not account for all variables in real-world snowdrift formation.
Is there a maximum wind speed that can be input into this calculator?
The calculator does not impose a specific limit on wind speed, but practical limitations exist based on physical constraints and data availability.
