[Turbulence Spectra and Scales](http://brennen.caltech.edu/FLUIDBOOK/basicfluiddynamics/turbulence/turbulencescales.pdf)<br>

<blockquote>Transition to turbulence begins when some flow instability (such as the instability analyzed in sections (Bkc) and (Bkd)) leads to some fairly large scale disturbance(s) or “eddies” in the flow field. As these disturbances gather energy from the mean flow, they begin to spawn smaller disturbances or eddies which, in turn spawn even smaller eddies. This process ends because, eventually, the eddies reach a size for which viscous effects become important and the very small eddies are damped out by viscosity. Eventually, the spectrum of spatial or temporal eddy sizes reaches a “fully developed” state in which energy is fed from the mean flow into large eddies and then continually cascades down to smaller and then smaller eddies eventually reaching a size at which viscosity becomes important and damps out those small eddies. In this fully-developed state the disturbance energy for any one size of eddy becomes relatively constant though it can, of course, continue to change with the flow conditions.</blockquote>

- mount anemometer higher up in the trees

- look into turbine tree mounting techniques

- finish week three and take week 2 quizzes

- work when it doesn't rain

- research boundary layers and atmospheric stability correction

- look into calculating the lift of solar panels (flat plate approximation - coefficient for lift and drag)
