Cold weather

Cold weather occurs when atmospheric temperatures drop significantly, often due to seasonal changes, high-pressure systems, or geographic location. It reduces the amount of heat energy in the air and on surfaces, which can affect health, infrastructure, and ecosystems. Cold air is denser and contains less moisture, leading to frost, snow, or ice when temperatures fall below freezing. Prolonged exposure can cause hypothermia or frostbite if proper precautions aren’t taken. Understanding cold weather helps in preparing for its impacts, such as dressing warmly, ensuring heating systems work, and taking care of vulnerable populations.
