Climate
The climate is mostly temperate, but tropical in Hawaii and Florida, arctic in Alaska, semiarid in the great plains west of the Mississippi River, and arid in the Great Basin of the southwest. Warm chinook winds from the eastern slopes of the Rocky Mountains occasionally ease low winter temperatures in the northwest.

Large urban clusters are spread throughout the eastern half of the US, particularly the Great Lakes area, northeast, east, and southeast, and the western-tier states. Mountainous areas such as the Rocky Mountains and Appalachians, deserts in the southwest, dense boreal forests in the extreme north, and central prairie states are less densely populated. Alaska's population is concentrated along its southern coast, particularly around Anchorage, while Hawaii's is centered on the island of Oahu.
