He had to turn his back to the wind flow to speak.
Similar is the case between artificially planned technologies and environmental currents (water, wind flows, other transport mechanisms).
Speciality of the wind flow is another factor which makes Ramakkalmedu unique.
He tweaked the controls, setting up a detector so the station could better analyze wind flow.
Among other things, their model now reflects gravity wave drag, a slowing effect that mountains have on wind flow.
These include orientation to the sun, soil type, wind flow, slopes, shade and climate.
Patterson found that each cup produced maximum torque when it was at 45 degrees to the wind flow.
The northern wind flow suddenly reversed direction about 6,000 miles below the surface, and it has maintained the new direction.
Since their time, trees and buildings have disrupted the wind flow, making flight harder.
The winds drive surface water to the right of the wind flow, that is offshore, which draws water up from below to replace it.
