define coriolis force and air currents?
Answers
Coriolis effect: An apparent force that arises because of the earth's spin around its axis. Freely-moving objects are deflected to the right of their direction of motion in the northern hemisphere and to the left of their direction of motion in the southern hemisphere.
a. an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation. On the earth, the effect tends to deflect moving objects to the right in the northern hemisphere and to the left in the southern and is important in the formation of cyclonic weather systems.
b. Air currents are concentrated areas of winds. They are mainly due to differences in pressure or temperature. They are divided into horizontal and vertical currents; both are present at mesoscale while horizontal ones dominate at synoptic scale.
