Because of the Coriolis force (the force caused by the Earth's rotation), winds south of the Equator change direction from southeast to southwest in the Arabian Sea and the Bay of Bengal.
Whereas the pattern of surface currents, controlled largely by the Earth's rotation, winds, water-density differences, and the geometry of basins, is relatively well understood, that of deeper water masses is more complex and less well known.
Explicit formulas for the critical wind speed for all three possible wind-induced accidents are derived to provide the new critical wind speed formulas for rollover and rotation wind-induced accidents.
For example, a static wind catcher is classified as passive; a rotating wind cowl as a directed passive technique and a rotating turbine ventilator is classified as outright active due to its constant rotation with the wind.
This anticyclone (circulation of winds around a central region of high atmospheric pressure) leads to southeast trade winds on its north side, since the rotation of wind around the high-pressure area is opposite to that in the Northern Hemisphere because of the Coriolis force (the effect caused by Earth's rotation).
The results showed that, the rotation of wind turbine had significant influence on wake, and higher the rotational speed, the greater reduction of the wake velocity.
Meanwhile, neither vortex deformation nor rotation of wind maxima is significant.
Mechanical energy is produced through the rotation of wind turbine blades by air that converts mechanical energy into electrical energy.
Variation in voltage fluctuation or variation in speed between high-speed shaft and low-speed shaft varies the rotation of wind turbines.
In the derivation of the equation of motion, non-linearities due to large lateral displacements as well as rotation, drag wind and wave forces, which are assumed to be proportional to the square relative velocity between the wind/wave and the mast, are considered.
The dome and telescope rest on separate sets of foundations (driven 20 m down into the volcanic basalt), to prevent vibrations caused by dome rotation or wind stresses on the building affecting the telescope pointing.
