The direction of air currents and wind direction would be expected to change as you travel from 15°S latitude to 15°N. This is because the Coriolis effect causes air currents to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, resulting in the reversal of wind direction between the two latitudes. The convection pattern and density of air might also change slightly, but the most noticeable difference would be in the direction of air currents and wind direction.
