In this post I want to share to you how to estimate wind speed as function of height. Wind velocity plays a significant role in influencing the dispersion of released fluids. Wind speed rises with altitude above the earth’s surface, so reference height should be specified. Typically, 10 m is used as the meteorological standard unless noted otherwise.
Wind speed is also a function of weather stability and on the terrain.
Weather stability relates to vertical temperature gradients and atmospheric turbulence. The Pasquill-Gifford (P-G) classes are commonly used, with class G excluded from dispersion modelling. Read More
