Weather indicators are tools and signs that help us understand current and future weather conditions. Common indicators include thermometers for measuring temperature, barometers for atmospheric pressure, and anemometers for wind speed. These instruments provide valuable data that meteorologists use to forecast the weather. In addition to instruments, natural signs can also serve as weather indicators. For example, a sudden drop in temperature may suggest an approaching storm, while the behavior of birds and insects can indicate changes in weather patterns. Observing these signs can help people prepare for different weather conditions.
