*Winds which blow all over the year in the same direction is know as planetary winds. These are also known as prevailing winds or permanent winds.

*Planetary winds can be classified in to three
1) Trade winds-- NorthEast Trade winds, SouthEast Trade winds
2) Westerlies -- North Westerlies, South Westerlies
South Westerlies commonly known as Furious Forties, Roaring Fifties and Shrieking Sixties
3) Easterlies -- known as polar Easterlies or Polar winds

*Coriolis effect is an effect on wind direction due to the rotation of the Earth on its own axis.
It's effect increases as we go towards high latitudes(i.e towards poles)
