When south-east trade winds cross the equator into the Northern Hemisphere, why do they deflect to the right?
Answer and explanation
Correct answer: Because of the Coriolis effect
The Coriolis effect results from Earth's rotation and changes the apparent path of moving air. In the Northern Hemisphere, moving air is deflected to its right relative to its direction of travel. Thus, after crossing the equator, the south-east trades acquire a north-easterly component; the pressure-gradient force still drives their general movement toward lower pressure.
