The strong distortion of laser fields in turbulence is due in large part to the coherent nature of a laser beam, which means that phase distortions in the laser field result in interference of the beam with itself and large fluctuations in the beam intensity.
Claire McCaskill is returning the private jet she used taxpayer dollars to fly, prompting roughly 432,481,021 pun-tastic articles using the word "turbulence."
"They aim to protect assets rather than chase returns, so short-term turbulence has less of an effect," says Anders Nordheim , Eurosif's head of research.

This suggests his latest recommendation is tactical in nature, and geared toward locking in profits and avoiding the risks of short-term turbulence in the exchange rate.
Specifically, the dimples create drag due to a delayed separation layer, and hence less turbulence behind the ball. (some studies say the turbulence is made smaller, and is thus reduced.)
The Eureka itself was to do with how bubbles behave acoustically when fragmenting in turbulence (for example underneath a breaking wave).
