The electrical charges created by the collision of super-cooled cloud droplets, graupel and ice crystals in turbulent wind currents ultimately result in lightning.

The contrast between the hot air near the flames and the surrounding cooler air results in complex, turbulent wind flows that can further fan the flames.
13.
Turbulent winds, heated by the sun, bounce off mountains and collide with other systems, each of which has its own spiraling, tumbling momentum.

John W . Miles suggested a surface wave generation mechanism which is initiated by turbulent wind shear flows based on the inviscid Orr-Sommerfeld equation in 1957.

One straw in this increasingly turbulent wind can be found at the major ratings agencies : the number of downgrades they assign to corporate bonds, compared with upgrades.
16.
However, seagulls, like people, find gusty, turbulent wind difficult to contend with, and under such circumstances, the water is also choppy and unpleasant.
17.
The contrast between the hot air near the flames and the surrounding cooler air results in complex, turbulent wind flows that can cause fires to spread in unpredictable ways.
18.
In the work of Phillips, the ocean surface is imagined to be initially flat ( " glassy " ), and a turbulent wind blows over the surface.
19.
Not only is the mean ( average ) wind speed reduced in the lee of the shelter, the wind is also less gusty, for turbulent wind fluctuations are also damped.

The pilots approached the landing strip despite turbulent winds that were too strong for a safe landing, the army said in a report on the Aug . 4, 1996, crash.
