Trade winds: are patterns which lie in the lower section of the troposphere near the earth's equator (direction: easterly wind)
Polar easterlies: are dry, cold winds that blow from the polar highs from higher pressure-to lower pressure.(direction: latitudinal)
westerlies: it causes tropical cyclones towards the poles (direction: west towards east)
Coriolis effect: deflection of moving objects. when someone views a rotating frame suppose moving clockwise (right) the direction of deflection is left vice versa for counter clockwise frame.
