In the middle latitudes, low-pressure systems are located over the during the summer as the surface heats quickly. However, in the winter, the high-pressure systems tend to form there as the air is cooler and sinks.

Tropics

Explanation:

The low-pressure system is an area where the air pressure is low and is formed under the areas of the wind divergence that occurs in the upper levels of the atmosphere.   Compared to the winter the high-pressure systems tend to form where the air is cool and sinks and are generally found in the polar areas and equator is the region that forms the convective currents zones and thus leads to the rising of the warm and the formation of a low-pressure system.
