We often hear the expression, "Everybody talks about weather, but nobody does anything about it." This is really not true today. Something is, indeed, being done. Today, meteorology is used to make people’s lives safer and better. Meteorologists are constantly studying the weather. Some meteorologists observe the weather, others analyze weather information, and still others make forecasts about the weather storms.
    The United States National Weather Service operates a network of weather stations through the U.S. The Weather Service has more than 400 stations where information about weather is collected and recorded. At these stations, weather observations are taken every hour, both during the day and night. The Weather Service issued 24-hour weather forecasts. It also issues 5-day forecasts, 10-day forecasts and even 30-day forecasts. It may seem hard to believe, but some types of weather forecasts are 95% accurate.
    In the year 1959, the United States launched its first weather satellite. This satellite was specially designed to collect, record, and send back weather information to earth. Since that time, several weather satellites have been sent into space. They continue to provide valuable weather information to meteorologist in all parts of the world.
