How do winds behave near the equator?

• Winds are mostly weak because the equator is a region of mostly low air pressure.

• Winds are generally strong because the equator is a region of mostly high air pressure.

• Winds are mostly weak because the equator is a region where low and high air pressure bands come together

• Winds are generally strong because the equator is where low and high air pressure bands come together.
