    When vertical wind shear is weak, typically the winds blowing relative to a thunderstorm's movement in the lower troposphere are too weak to "restrain" the dense cold pool, allowing the gust front to race away from the storm and ultimately leading to the storm's quick demise. But, as vertical wind shear increases in the atmosphere, conditions become more favorable for thunderstorms to take on ...

    Wind turbines and the wind energy

    A wind turbine is a device for converting the kinetic energy in wind into the mechanical energy of a rotating shaft. Usually that rotating mechanical energy is converted immediately by a generator into electrical energy. In the large turbines, such as those shown in the picture above, there is generally a generator on top of the tower. The generator is usually connected to the turbine shaft ...
