# How to calculate column averaged kinetic energy?

I have u-wind, v-wind and w-wind at 11 pressure levels (starting from 1000 to 100). I would like to calculate column averaged kinetic energy. I have the formula to do this as:

$KE=\frac 1{g(Ps-Ptop)}$$\int_{Ptop}^{Ps}\frac 12(u^2+v^2+w^2)dp$

My question is how to use this formula to compute column averaged kinetic energy? Can I do it simply as follows:

$KE=\frac 1{9.8(1000-100)}\frac12[ \sum_{Ptop}^{Ps}(u^2+v^2+w^2)]$

Where the [ ] is the sum of $u^2+v^2+w^2$ at all 11 pressure levels

• you are looking at integration and specifically numerically integration. – gansub Jun 21 '17 at 14:07
