Students predict tomorrow's weather.



Understanding and forecasting weather is complicated. It is now recognized that long term forecasting must include observations of ocean and atmospheric patterns. Until about 1920, most forecasting was based almost exclusively on practical experience. Recording solar radiation (temperature), humidity (hygrometer), air pressure (barometer) and cloud cover help people interpret and determine patterns.

Between 1920-1930 charting air mass movements and charting fronts greatly improved forecasting of weather patterns. After 1930 mathematical analysis and interpretation of motion of physical models that could be produced experimentally. These equations aid in forecasting.

Starting in the late 1960's, satellite images also provided continuous information. Today, information from satellites provide a detailed documentation of temperature, solar radiation, cloud movement that provided unparalleled control.

  1. The Internet is rich with information that have only been available recently tot he public. Go over the following Internet sites that can provide data for students for years to come.
    This site links to many other sites that have live image feeds. You can find your local area so students can learn how to access information. You never know when students want to know the weather for a sporting event!
    This site is the government agency responsible for weather services. The National Oceanographic and Atmospheric Agency provides information from satellite feeds and other types of monitoring system throughout the world. The National Weather Service is responsible for the weather.
    Students could compare the temperature and/or precipitation the year they were born and last year.

    Severe weather site created by student doing research. Severe weather storms, hurricanes, and tornadoes are highlighted. Many links to other web sites.
    Australian severe weather atlas including wonderful weather photography, cyclones, lightning data, weather techniques and much more.

    Cooperative Institute for Research in the Atmosphere of Colorado State University.
  2. If you donít have access to the internet bring in newspapers and find the weather section. Make sure that students can find, read, and interpret the maps.
