What does sub polar latitudes do?

Subpolar latitudes, located between approximately 50° and 70° north and south of the equator, experience significant seasonal variations in daylight and temperature. These regions often have cold climates, with long winters and short summers, influencing ecosystems and human activities. The subpolar zones also play a crucial role in global climate systems, particularly in the regulation of ocean currents and atmospheric patterns. Additionally, they are characterized by unique habitats, such as tundra and boreal forests, which support diverse wildlife.
