Option A is correct. The image below shows Polar easterlies that curve due to air above equator being relatively warmer.
Polar easterlies:
These global winds are cold and dry. They are irregular, weak winds. These global winds are because of the polar high atmospheric pressure.
Here in the picture,
- The equator is at [tex]\bold {O^o}[/tex]
- Curved arrows at the top and the bottom to towards [tex]\bold {60^o}[/tex] south and north latitude.
The cold air comes from the north pole and south pole, can be seen by the curved arrow. They create a high pressure zone.
Therefore, The image below shows polar easterlies that curve due to air above equator being relatively warmer.
