Factors that Regulate the Climate
Anchorage is about 60 degrees N latitude, in a low pressure area. Therefore Anchorage, Alaska is at a doldrum latitude and is fairly windy because Anchorage is right in between the Polar North easterlies and the South westerlies. Anchorage is right on the coast of the Knik Arm in Alaska giving Alaska a slightly more stable temperature because of the water near it. Its topography is hilly if not mountainous. Anchorage is at a high elevation because of the mountains so therefore the air pressure is even lower. Due to its cold, dry weather, Anchorage does not have a lot of rainfall even though it is right next to a bay.
