A weather database is a collection of information that records various weather conditions over time. This data can include temperature, humidity, wind speed, and precipitation levels. By storing this information, scientists and meteorologists can analyze patterns and trends, helping them predict future weather events. These databases often gather data from multiple sources, such as weather stations, satellites, and buoys. For example, the National Oceanic and Atmospheric Administration (NOAA) maintains a comprehensive weather database that is used for research and public forecasting. This information is crucial for planning activities, preparing for storms, and understanding climate change.
