equator

Near the equator, though, the pattern flips across a wide area, creating a striking difference between the two zones.

SAI efforts concentrated near the poles, for example, could disrupt tropical monsoons, while releases near the equator might alter jet streams and interfere with global air circulation.

One possibility is that these eccentric warm Jupiters have companion planets that somehow alter their orbits without misaligning them relative to their stars' equator.

This is when Sun is directly above Earth's equator resulting in almost equal time of the length of day and night.

Those changes will be harshest in tropical regions of Southeast Asia, South America and Africa that are close to the equator, the study says.
