Weather changes refer to the variations in atmospheric conditions that occur over time. These changes can include shifts in temperature, humidity, wind speed, and precipitation. For example, a sunny day can quickly turn into a rainy one due to the movement of weather fronts, which are boundaries between different air masses. Factors such as seasonal changes, geographical location, and climate patterns like El Niño can influence weather changes. These variations can affect daily activities, agriculture, and even ecosystems. Understanding weather changes helps people prepare for different conditions and make informed decisions.
