The movement of air with respect to the earth's surface, caused locally by the sun's heating of the ground; and globally, by the sun's radiation and the spin of the earth.

A localized wind that is warmed by sunshine, rises, and blows up a slope.

1. A violent, cold, dry strong northeasterly winter wind that blows down the mountains of central Europe and along the shores of the Adriatic Sea.
2. A wind with a source so cold that, when the air reaches the lowlands or the coast, the dynamic warming is inadequate to raise the air temperature to the normal level for the region; therefore, it is experienced as a cold wind.

Special terms for this wind include, borino, "weak bora" and boraccia, "strong bora".

Winds that occur in a valley as the air cools and flow down the slope; usually, after sunset.

1. A hot humid south or southeast wind of southern Italy, Sicily, and the Mediterranean islands, originating in the Sahara Desert as a dry dusty wind but becoming moist as it passes over the Mediterranean.
2. A hot or warm southerly wind, especially one moving toward a low barometric pressure center.
3. The air comes from the Sahara (as a desert wind) and although it is dry and dusty, the term is not used in North Africa, where it is called chom, "hot" or arifi, "thirsty".

In crossing the Mediterranean the sirocco picks up a great deal of moisture because of its high temperature, and reaches Malta, Sicily, and southern Italy as a very enervating, hot, humid wind.

As it travels northward, it causes fog and rain. There are a number of local variants of the spelling such as xaroco (Portuguese), jaloque or xaloque (Spanish), xaloc or xaloch (Catalonian).

4. Etymology: "hot wind blowing from the Libyan deserts" from the 1610's, from Italian sirocco, from common Arabic shoruq, "the east wind", from Arabic sharqi, "eastern, east wind", from sharq, "east", from sharaqa, "to rise" (in reference to the sun).

1. A stream of charged atomic particles, mostly protons an electrons, from the sun's corona, flowing outwards at speeds of between 300 kilometers per second or 200 miles per second and 1,000 kilometers per second or 600 miles per second.
2. The stream of charged particles "blown" by the thermal pressure of the sun out from its corona, which it can not retain by gravity.

In the vicinity of the earth, these particles have a velocity of about 300 miles, or 500 kilometers, per second.

The stream of particles "blown" by the radiative pressure of a star away into space.

Making use of wind turbines to produce energy.

Wind energy uses the energy in the wind for practical purposes like generating electricity, charging batteries, pumping water, or grinding grain.

Turbines are perched on high towers, usually 100 feet or higher, and often placed in large groups, or "farms", to generate electricity to towns and cities.

On a much smaller scale, stand-alone turbines are sometimes used by farmers and homeowners to generate supplemental electricity.

In the past twenty years, U.S. government incentives in the form of tax credits to producers and incentives for homeowners have helped to lower the price of wind power by an estimated eighty-five percent, making it a more feasible option.

There are people who object to wind farms because of their appearance or the noise the turbines make. Wind power raises few other environmental problems except danger to birds.

There is also a problem with having a consistent generation of electricity with wind energy because of the of the unknown features of the weather. Sometimes the wind is simply non-active.

1. To bring to an ending; "Let's wind up this meeting now, please."
2. To start; "Wind up the clock now so it will start keeping time and start the alarm in the morning."
