This basic explanation of the greenhouse effect is accompanied by a diagram. Full description.

This article describes the global weather factors used by Colorado State University Professor William Gray to make predictions on the number and severity of storms that will occur in a hurricane season. Links to forecasts and to other weather-related topics are included. Full description.

This guide presents introductory information about satellites and remote sensing and their uses in meteorological observations and forecasting. Topics include geostationary and polar orbiting satellites, orbital coverage, architecture, instruments, and the types of data they produce. A tutorial on interpreting satellite images is also included. Full description.

Visitors to this site can access information on tropical storms and hurricanes in the Atlantic Ocean as far back as 1851. Information provided here includes a yearly map showing the tracks of all storms, and individual maps for each storm. The individual maps are accompanied by data tables that show latitude, longitude, wind speed, dates, and times. Full description.

Students can use this map to track the progress of hurricanes and tropical storms in the western Atlantic Ocean and Carribean Sea. It includes descriptions of hurricane watch and warning conditions. Full description.

Visitors to this site can read a discussion about the weather in Anarctica, including why it is so cold, how weather observations are conducted there, and what role the continent plays in the global weather system. Links to related topics, a wind chill calculator, and a Fahrenheit-Celsius-Kelvin temperature converter are also provided. Full description.

DataStreme Atmosphere is a major precollege teacher enhancement initiative of the American Meteorological Society (AMS), supported by the National Oceanic and Atmospheric Administration (NOAA). Its main goal is the training of Weather Education Resource Teachers who will promote the teaching of science, mathematics and technology using weather as a vehicle, across the K-12 curriculum in their home ...

These documents describe the potential impacts of global climate change in each of the fifty states. Impacts discussed include temperature change, changes in precipitation, human health effects, rise in sea level, and changes to water supplies. Additional impacts are predicted for agriculture, forest cover, and sensitive ecosystems. Full description.

This site, produced by the U.S. Geological Survey, describes the circulation pattern of Earth's atmosphere, which is influenced by differential heating and the Coriolis Effect. This circulation causes the formation of warm, dry areas on the Earth's surface which are where deserts are likely to exist. The site features text, a photograph, and a scientific illustration showing the atmospheric circulation ... Full description.

In the winter of 1999-2000, relatively little snow cover blanketed North America, and it melted early. Users can read and view satellite imagery that discusses how NASA's Terra satellite and its Moderate Resolution Imaging Spectrometer (MODIS) were able to record this phenomenon, and how spring snow cover data can be used to predict flood or drought conditions.
