Weather Forecasting


QC 995 General Works, Treaties, and Textbooks


Ag Weather, a site sponsored by Ceres Online, is a gateway to satellite maps, temperature and storm maps, as well as California weather data. The images are up-to-the minute representations of weather affecting both the United States and the world.
The directory features eight data categories: a world map; a national satellite map; a national surface temperature map; a western states satellite map; a pacific storm map; a "hot spot" link (an in-depth map of an area affected by much weather activity); as well as the CIMIS data system and the CASS crop report. The world map is a full-color representation of the temperature ranges presently occurring; a graph underneath interprets the findings. Access is provided to the California Irrigation Management Information System (CIMIS), a series of eighty-five computerized weather stations within that state. Users can located data on CIMIS stations, daily data, and monthly data collected by the stations. California crop weather, collected on a weekly basis, is found under the CASS category. All of the available map categories download detailed presentations of their subjects, updated continuously for accuracy.
The site is maintained as a service of Ceres Online.

Real-Time Weather Data for Meteorologists

Real-Time Weather Data for Meteorologists offers current weather information for meteorologists through satellite, radar, surface, upper-air, aviation, and numerical model coverage. Upon accessing the site, users should note that the various site divisions are accessible in three manners: (1) via icons (images) displayed on the left of the screen; (2) via top links within the site; and (3) via links within the various site division descriptions. Within the site, users have access to: (1) the satellite page; (2) the radar page; (3) the surface page; (4) the upper-air page; (5) the aviation weather page; (6) the numerical model page; and (7) the miscellaneous weather page. In all cases, users should consult the site for a comprehensive listing of all information available within a given site page. Noted within this description are major features of each page, not all applicable data.
The satellite page offers "images of clouds taken from space by [the] geostationary satellite...GOES-8...orbiting the earth at an altitude of 35,800km." This area offers the latest satellite imagery from the source, continental U.S. coverage (in five areas), and regional close-ups from ten U.S. cities. The radar page features "links to hourly images of radar reflectivity data obtained by the National Weather Service NEXRAD...doppler radars." Here, users will find hourly data, national composites, and state-based information, via a U.S. map. The surface page contains "plots of raw hourly suface data including temperature, dewpoint temperature, wind, and air pressure on close-up regional maps of the U.S." Within this area, users will also find contour plots, Mesonet plots, and local weather links. The upper-air page features "raw temperature, moisture, and wind data from weather balloons called [is] presented on schematic diagrams called Skew-T/Log-P plots...." Plots are found for the range of 200-850mb; Rawinsonde data can be found from a U.S. map.
The aviation weather page offers "plots of specific aviation-related data including pilot reports (PIREPs) of icing and turbulence, AIRmen METeorological bulletins (AIRMETs), and SIGnificant METeorological bulletins (SIGMETs)." Users can customize their own PIREP plot via fields within a provided table. The numerical model page offers "plots derived from numerical weather forecast models that are run on high-end workstations or supercomputers." This area offers NCEP Rapid Update Cycle (RUC) models, RUC forecasts, an Eta model, and a global spectral model. The final site division, the miscellaneous weather page, offers links to other weather sites, access to the RAP weather machine, and links to general weather information.
The site is sponsored by the Research Applications Program; National Center for Atmospheric Research (NCAR); Boulder, Colorado.

Weather Visualizer

The Weather Visualizer is a service of the Department of Atmospheric Sciences at the University of Illinois Urbana-Champaign which allows users to custom-design their own weather maps and images. From six major links provided on the main page, the user can select features, images, and overlays to build maps with specified data and information. In all cases, users will receive their completed maps about one to two minutes after completing the map's formulation.
At the top of the site's main page are links to a text version of the site, a Java version of the site, and a user feedback area. In the large map image area, the site's major links are noted: (1) surface observations; (2) upper air soundings; (3) satellite imagery; (4) upper air observations; (5) forecast products; and (6) radar summary. Below the map are links to general site information and to e-mail the site's creators.
"Surface observations" provides map configuration choices in terms of surface parameters and overlay options. "Upper air soundings" offers plots of recent timeframes and of the previous 48 hours. "Satellite imagery" details various kinds of satellite images; "upper air observations" offers parameters, overlay options, viewing levels, regions, and time restrictions. "Forecast products" features text-based forecasts, Model Output Statistics (MOS) graphical forecasts, gridded graphical forecasts, and other resources. The last link, "radar summary" details overlay options, regions, and observation times.
In all cases, map configuration choices allow selections in: parameters, overlay options, region, and observation time. After making choices in these areas, the user will receive the site-produced map for observation and study. The site is sponsored by the Department of Atmospheric Sciences at the University of Illinois, Urbana-Champaign.
