As you travel from 15°S latitude to 15°N latitude, you would encounter changes in air currents primarily due to the shifting location of the Intertropical Convergence Zone (ITCZ) and the influence of the Coriolis effect.
-
Convection Pattern: The tropical regions around the equator are characterized by strong convection due to intense solar heating. You would see alterations in convection patterns as you move from the southern hemisphere, where air generally rises around the ITCZ, to the northern hemisphere, where the ITCZ shifts northward during certain seasons.
-
Jet Stream: Near the equator at low latitudes, you generally do not find a strong jet stream. However, as you move to higher latitudes (towards 30°N), the mid-latitude jet stream becomes more prominent, which influences both weather patterns and air current directions.
-
Air Current Directions: The Coriolis effect will cause air moving from the equator towards the poles to deflect to the right in the northern hemisphere and to the left in the southern hemisphere. As you cross the equator, there would be a noticeable change in the direction of the prevailing winds.
-
Wind Directions: Trade winds in the tropics are predominantly easterly. As you transition through the tropics from 15°S to 15°N, you will continue to experience these easterly trade winds, but as you approach the ITCZ or beyond, you might find variations in wind direction influenced by local topography and weather systems.
In summary, the changes in air currents moving from 15°S to 15°N will reflect adjustments in convection patterns, shifts related to the jet stream, variations in air current directions due to the Coriolis effect, and the dominance of trade winds.
