Secondary or Periodic Winds Seasonal winds: These winds change their direction in different seasons. For example monsoons in India. Periodic winds: Land and sea breeze, mountain and valley breeze 3. Local winds These a small area Winds like Loo, Mistral, Foehn, Bora. blow only during a particular period of the day or year in


  8. Primary Winds or Prevailing Winds or Permanent Winds or Planetary Winds Threse ant the planetary winds which blow extensively over continents and oceans The two most well- understood and significant winds for climate and human activities are trade winds and westerly winds.

  12. Trade Winds . The trade winds are those blowing from the sub-tropical high pressure areas towards the equatorial low pressure belt. .Therefore, these are confined to a region between 30 N and 30 S throughout the earth's surface. They flow as the north-eastern trades in the northern hemisphere and the south-eastern trades in the southern hemisphere. . This deflection in their ideally expected north-south direction is explained on the basis of Coriolis force and Farrel's law.


  13. The horse latitudes are regions located at about 30 degrees north and south of the equator. These latitudes are characterized by calm winds and little prec pitation. The horse latitudes are located at about 30 degrees north and south of the equator. It is common in this region of the subtropics for wind:s to diverge and either flow toward the poles (known as the prevailing westerlies) or toward the equator (known as the trade winds). These diverging winds are the result of an area of high pressure, which is characterized by calm winds, sunny skies, and little or no precipitation. According to legend, the term comes from ships sailing to the New World that would often become stalled for days or even weeks when they encountered areas of high pressure and calm winds. Many of these ships carried horses to the Americas as part of their cargo. Unable to sail and resupply due to lack of wind, crews often ran out of drinking water. To conserve scarce water, sailors on these ships would sometimes throw the horses they were transporting overboard. Thus, the phrase 'horse latitudes' was born


  14. Westerlies .The westerlies are the winds blowing from the sub-tropical high pressure belts towards the sub polar low pressur belts Thev blow from southwest to north-east in the northern hemisphere and north-west to south-east in the southern hemisphere The westerlies of the southern hemi phere are tronger and persistent due to the vast expanse of water, while those of the northern hemisphere are ir egular because of uneven relief of vast land-masses. The westerlies are best developed between 40 and 65 S latitudes. These latitudes are often called Roaring Forties, Furious Fifties, and Shrieking Sixties - dreaded terms for sail rs. The poleward boundary of the westerlies is highly fluctuating. There are many seasonal and short-term fluctuations. These winds produce wet spells and variability in weather.

  16. Polar easterlies .The Polar easterlies are dry, cold prevailing winds blowing from north-east to south-west direction in Northern Hemisphere and south-east to north-west in Southern Hemisphere. They blow from the polar high-pressure areas of the sub- polar lows

  18. Monsoons . Monsoons were traditionally explained as land and sea breezes on a large scale. Thus, they were considered a convectional circulation on a giant scale. . The monsoons are characterized by seasonal reversal of wind directior During summer, the trade winds of southern hemisphere are pulled northwards by an apparent northward movement of the sun and by an intense low pressure core in the north-west of the Indian sub- continent. While crossing the equator, these winds get deflected to their right under the effect of Coriolis force.


  19. The monsoon winds flow over India, Pakistan, Bangladesh, Myanmar (Burma), Sri Lanka, the Arabian Sea, Bay of Bengal, southeastern Asia, northern Australia, China and . Outside India, in the eastern Asiatic countries, such as China and Japan, the winter monsoon is stronger than the summer monsoon. (we will study about monsoons in detail while studying Indian Climate)
