Tempe's air pressure is affected by its location in the Sonoran Desert. The desert's dry air increases pressure, making it relatively high. Tempe's valley geography traps and heats air, increasing pressure further. In summer, hot air rises, causing low pressure and extreme heat. In winter, cold air sinks, bringing high pressure and mild temperatures. As a desert city, it has a hot desert climate, characterized by high pressure during winter and low pressure in summer, leading to large temperature differences between seasons.
