Changes in weather patterns in Roswell cause barometric pressure to rise and fall. Atmospheric pressure increases when a high-pressure system moves in, and decreases when a low-pressure system arrives.
Roswell's elevation of about 360 feet above sea level and its hilly landscape affect atmospheric pressure. The surrounding hills can trap or redirect air masses, influencing pressure variations.
During winter, Roswell's pressure is usually higher due to cold, dense air. In summer, pressure is lower due to warm, rising air. Spring and fall bring moderate pressure with mild temperatures.
