Pittsburgh is situated in a valley. The surrounding hills and mountains play a significant role in shaping the local weather. The city's location near the confluence of two rivers also affects the atmospheric conditions. The rivers moderate the temperature and humidity. The valley traps the air, making the city's weather more stable. However, this also means that Pittsburgh can experience poor air quality. The surrounding terrain blocks winds, causing air to stagnate.
