Anything that lives in or which is carried by the wind, breeze, etc.
- There are many air borne aerocolas; such as, pollen that may cause hay fever or other respiratory illnesses among animals.
- Feathered birds and insects of the air are distributed over the aerocolas of the earth and are inhabiting almost every possible area other than the deep oceans.
- Birds have special places in aerocolas, ranging in size from very tiny hummingbirds, that weigh just a few grams, to eagles.
- The numbers of insects that exist in aerocolas is impossible to determine because there are so many different species.
2. A movement of air generated artificially, as by a bellows or a fan: "Lori and Edna had the fan on to make some wind in their very hot and humid room."
2. To coil the spring of a mechanism by turning a stem or cord: "Wanda had to wind her old-fashioned watch every day or it would not keep time."
While sailing on the weekend, there was a strong wind and Kevin and his crew had a problem trying to wind the sail; however, later they all wined and dined when the situation was much calmer.
Anabatic wind is caused by the difference in density between the warm ground air and the cooler air in the free atmosphere.
2. A condition in the wood of some trees in which the rings are separated, as some suppose, by the action of high winds upon the trunks of those trees.
About one-fifth of the Denmark's electricity comes from wind, which wind experts say is the highest proportion of any country.
A closer look shows that Denmark is a far cry from a clean-energy paradise.
The building of wind turbines has virtually ground to a halt since subsidies were cut back.
Meanwhile, compared with others in the European Union, Danes remain above-average emitters of the greenhouse gas carbon dioxide.
For all of its wind turbines, a large proportion of the rest of Denmark's power is generated by plants that burn imported coal.
The Danish experience shows how difficult it can be for countries grown rich on fossil fuels to switch to renewable energy sources like wind power.
Among the hurdles are fluctuating political priorities, the high cost of putting new turbines offshore, concern about public acceptance of large wind turbines, and the destructive volatility of the wind itself.
Some parts of western Denmark derive 100 percent of their peak needs from wind if the breeze is up.
Germany and Spain generate more power in absolute terms, but in those countries wind still accounts for a far smaller proportion of the electricity generated. The average for all 27 European Union countries is three percent.
The Germans and the Spanish are catching up as Denmark slows down.
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".
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).
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.
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.
