In Quebec, the barometric pressure fluctuates throughout the year, bringing varying weather patterns. In winter, when temperatures drop, the air becomes denser, leading to higher barometric pressure. In summer, the opposite occurs as warm air rises, causing lower pressure and the potential for thunderstorms.
The landscape of Quebec, with its vast forests, lakes, and mountains, also influences atmospheric pressure. The interaction between these features and the air creates local weather patterns. For instance, mountains can act as barriers for air masses, causing differences in pressure between regions. Additionally, the Great Lakes system affects the weather, as the temperature of the water can influence the air above it, leading to changes in pressure and precipitation.
