As you travel from 15°S latitude to 15°N latitude, you would expect changes in air current directions. This is due to the Coriolis effect and the global circulation patterns, which influence how air moves in different latitudinal zones.
In general, air currents tend to flow from high-pressure areas to low-pressure areas, and as you move toward the equator, the direction of these currents can shift due to the rotation of the Earth. In the tropics (around the equator), these effects lead to rising warm air and the formation of trade winds that move from east to west.
So, the correct response to your question would be Air current directions.
