The three major factors that help determine the flow of air at lower altitudes, are Coriolis force, convective currents and the presence of frictional force.
As we know the air in the troposphere consists of 99% of the moisture and dust and gases and hence most of the weather phenomena take place under or up to this layer hence known as homosphere.
The Coriolis force which related to the rotational spinning of the earth on its axis is a force that leads to the flow of air current and the movement of winds in right in the north and the left in southern direction.
The impact of the sun's rays have on the earth produced a convective current that warms up the equatorial zones and this warm air moves upwards and reaches the polar and the descent of the polar winds created a high and low-pressure belt, all of these factors are accompanied by the landscape of the earth.
