Wind calculations:
Vz = Vg (z/zg) 1/a ---> 0 <z <zg

Vz = speed of wind wind at height (z)

Vg = gradient od wind at height (Vg)

a = exponential coefficient (from google definitions: Exponential Functions. If is a positive real number other than one and a is any real number, then f(x) = a b^{x} is an exponential function. In this definition, a is known as the coefficient, b is called the base, and x is the exponent. ... Further, all such ratios must be constant, so they all must be the same number.)

Accumalated Cyclone Energy (ACE) calculations:
ACE = Wind in kts squared/10,000 (for every 6 hour update)
