JUNE 15 is celebrated as “GLOBAL WIND DAY” across the world to raise awareness about the importance of WIND ENERGY
WHAT IS WIND? Wind is moving air and is a form of Energy. It is caused by the difference in air pressure with in our atmosphere. Under high pressure, air moves towards areas of low pressure. Let us tell you the greater the difference in pressure, the faster the air flows. 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.
HOW WIND IS FORMED? WINDS 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’S HAVE A LOOk ON THIS PHENOMENA
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 LOW-PRESSURE SYSTEM. At the same time, cooler air moves surface of the earth from towards the equator to replace the heated air, This is known as “HIGH-PRESSURE SYSTEM”.Winds generally blow from high-pressure area to low-pressure areas.The boundaries between these two areas is known as “FRONT”. The Areas where these prevailing winds met is known as CONVERGENCE ZONES .
GLOBAL WIND DAY was started in Europe first in 2007 and at Global level in 2009″. It is a day when wind energy is celebrated, information is exchanged and adults and children find about wind energy, its power and possibilities it holds to change the World. people used to visit wind farms on this day, meet experts, attend events and take actions to Support
WIND ENERGY.
