METEOROLOGY – WIND CALCULATOR
Turbulence Intensity
A precise tool.
What is the Turbulence Intensity & How does it work?
Turbulence intensity in meteorology is a measure of the variability of wind speed over time and space, which can be influenced by various factors including terrain roughness. The terrain’s surface characteristics play a significant role in determining how air flows around it, affecting turbulence levels.
The relationship between turbulence intensity and terrain roughness can be quantified using specific models that consider parameters such as the height of obstacles and their distribution across the landscape. These models help meteorologists predict wind behavior in complex terrains, which is crucial for aviation safety, wind energy applications, and other fields.
