World Wind Day
History of Global Wind Day:
Global Wind Day was inaugurated in 2007 as Wind Day and it only came to be known by the current name in 2009. It had been organised by the European Wind Energy Association (EWEA), and in 2007 it had reached 18 countries in Europe, with around 35,000 people taking part in it. The day is marked on June 15 every year.
What is Wind energy?
The wind is moving air and is a form of energy. It is caused by differences in air pressure within our atmosphere. Under high pressure, air moves toward areas of low pressure. Let us tell you that the greater the difference in pressure, the faster the air flows. As we know that Cyclone Vayu may hit the Gujarat state. It is also the windstorm which may cause landfills. Winds can range from a light breeze on a hot summer day to tornadoes and hurricanes or cyclones with speeds of hundreds of kilometers per hour.
When we see Air, it does not seem like anything but during a windstorm, its presence can be seen. Wind may lift roofs off buildings, blow down power lines, accidents at highways, push car, trucks etc.
How Wind is formed?
It is formed by the uneven heating of the Earth by the sun. You can't see it but you can feel it. When there is a difference in atmospheric pressure winds are generated. Let us understand the phenomena:
At the Equator, due to sun water and land are more warm as any other part of the globe. Therefore, warm equatorial air rises higher into the atmosphere and migrates towards the poles. This is known as a low-pressure system. Now, at the same time, cooler or denser air moves over the surface of the earth towards the equator to replace the heated air. This is known as a high-pressure system. Winds generally blow from a high-pressure areas to low-pressure areas. And the boundaries between these two areas is known as the front. Various types of wind and weather patterns are caused between fronts. Like prevailing winds that blow from a single direction over a specific area if the Earth. And the areas where these prevailing winds meet are known as convergence zones.
Please use nature energy. Like solar panels, wind plant.
