Atmospheric fronts are boundaries that separate different air masses in the atmosphere. These air masses can have varying temperatures and humidity levels, leading to changes in weather conditions. There are several types of fronts, including cold fronts, warm fronts, stationary fronts, and occluded fronts, each affecting the weather in distinct ways. When a cold front moves in, it typically brings cooler temperatures and can cause thunderstorms. In contrast, a warm front usually leads to gradual warming and can result in prolonged rain. Understanding atmospheric fronts is essential for meteorologists to predict weather patterns and inform the public about upcoming changes.
