To convert wind speed collected at ground level to 80-m, hub-height equivalents, I used the formula described by van den Berg (2006): V80-m /V1-m = (h80-m /h1-m )m. Where velocity of the wind at 80-m is a power function of the ratio of hub and anemometer heights. The shear exponent m is an expression of atmospheric stability.

https://info.5y1.org/wind-power-calculation-formula_1_323ca3.html
Power Dissipation Index (PDI) for a tropical cyclone is defined as, "the sum of the maximum one-minute sustained wind speed cubed, at six-hourly intervals, for all periods when the cyclone is at least tropical storm strength". I apply a scaling factor so as to match the scale that Emanuel uses. Data on each storm's "maximum one-minute sustained

Here we would modify the calculation of power between the rated speed and the cut-out speed. The new amount of power generated in this interval would be found from the following equation. Adding this value to the 336,583 W produced for operation below the rated wind speed gives the average power …

The table of cumulative wind power fractions, shown below, is used to determine the fraction of the total power in the wind that is between two wind speeds V1 and V2. To use this table you first compute V1/c and V2/c and find the table entries for these values of V/c at the k value for your wind speed distribution.
