Weather measurement involves the use of various instruments to observe and record atmospheric conditions. Common tools include thermometers for temperature, barometers for air pressure, and anemometers for wind speed. These measurements help meteorologists understand current weather patterns and predict future conditions. Additionally, rain gauges are used to measure precipitation, while hygrometers assess humidity levels in the air. By collecting and analyzing this data, scientists can provide accurate weather forecasts, which are essential for daily activities, agriculture, and disaster preparedness.
