Rain or Shine Today
Most people get up in the morning and check some kind of weather report before planning their day (others just look out the window to see what’s happening). What the report may say is something like “30% chance of rain this morning” – not a specific “it will rain”. There is a certain level of uncertainty to predicting the weather.
News You Can Use
- Weather reports are available from a variety of sources. Local radio and television stations broadcast reports, usually during their news programs. Newspapers print reports, but they may be out of date since the paper is printed late at night and then distributed. Increasingly, people get their weather news on their cell phones or on the internet. Weather services update their forecasts frequently, so they are the most current sources of weather information.
- Many TV stations have at least one weather person on staff. This individual may be a trained meteorologist (with a college degree in the subject) or someone who has learned how to organize and assemble local weather information for broadcast. The term “meteorologist” should be restricted to those individuals with a degree in the subject.
- Weather data from around the world is gathered using a variety of high technologies, including satellites and radar. This information is fed to the supercomputers at the National Centers for Environmental Prediction in Maryland. There the numbers are crunched, trends are analyzed, and predictions are made.
