Ames is situated in the Midwestern United States, where the Great Plains meet the Midwest. The city is surrounded by flat to gently sloping terrain. This flat landscape allows winds to travel long distances without obstruction.
The lack of topographical features means there are no mountains to disrupt or block air masses. As a result, Ames experiences a relatively consistent atmospheric pressure.
The city's proximity to the Gulf of Mexico and the Rocky Mountains also affects the atmospheric pressure. Moist air from the Gulf brings warm, humid air that leads to higher pressure. Conversely, cold, dry air from the Rockies leads to lower pressure.
