1. INTRODUCTION
Many university coursesutilize Internet resources tosupplement lecture material and/orprovide a laboratory setting forlearning outside the classroom, butoften find ‘web-books’ containingonly text with few or no examples.The problem with this – especiallywithin meteorology – is thataccurate, useful, and if possible,real-life examples of weatherphenomena are necessary to bestenhance the educational process.
The implementation ofcurrent weather products into theWeather World 2010 (WW2010 –http://ww2010.atmos.uiuc.edu/)web server (example product inFigure 1) offers such real-lifeexamples of educational materialin the atmospheric sciences.Furthermore, WW2010 places thisuseful reference information oneclick away from each weather product. Thiscreates a unique interrelationship and provides avisual learning experience to the learner.
2. EDUCATIONAL MATERIAL
WW2010’s educational content includesonline case studies, instructional modulesspanning topics from the hydrologic cycle tosatellites to El Niño, and weather map tutorials.Each of these contain text content supplementedwith examples in the form of movies, diagrams,and photographs – offering instructors andstudents alike an ideal Internet learningenvironment (Bramer, et al. 1998).
2.1 Helper Pages
Each of these instructional modules isself-contained, yet all are cross-linked throughintermediate helper pages. These helper pagesare part of the user-friendly navigation inWW2010. Users can access definitions,illustrations, and examples of meteorologicalkeywords that are found in another part ofWW2010 without getting lost; offering theopportunity to return to the original page if desiredor to continue in the new area of WW2010.
2.2 Advancements in Multimedia Technology
WW2010 developers have made strides tofurther push the envelope of technology within theeducational framework. Streaming videos canexplain atmospheric observations, forces, andprocesses. Advancements have been made increating a web-based virtual-reality learning

environment (VRLE) as a means to furtherenlighten teachers and students by offering 3-Dexplorable environments of atmosphericphenomenon. More details on this subject can befound in two companion papers (Ramamurthy, etal. 1999; Plutchak, et al. 1999).
3. CURRENT WEATHER PRODUCTS
The new current weather productsdeveloped by WW2010 are simple in design yetvery effective. They are meant for anyoneinterested in weather, and are easy to utilize.However, advanced products are also available tothe most avid weather enthusiast.
3.1 User Interface
The current weather products have afront-end interface (example in Figure 2) thatoffers the user various choices in productselection. He or she can choose from varioustypes of weather maps – ranging from surface toupper air; from satellites to forecasts. Also, aseparate list of novice selections is available togive introductory students a smaller and simplerset of choices.
Figure 2. WW2010 Current Weather Interface
3.2 Product Features
Choosing a product from the selection listgenerates the desired map within a new browserwindow. Special buttons have been placed belowthe map to allow user-navigation through time or
create a recent animation. Each subsequentproduct the user requests emerges within a newbrowser window. This allows multiple products tobe displayed simultaneously. Clicking the exitbutton can terminate the product window. Moredetails on the products themselves can be foundin a companion paper (Wojtowicz, et al. 1999).
4. TWO-WAY INTEGRATION
The integration of WW2010 weatherproducts into this environment creates a dynamictwo-way effect where a student can use theavailable educational content as a reference forthe weather products and vice versa.
4.1 Products linked to WW2010 LearningModules
Under each weather product is a helpbutton. This is to be pressed if the learner wants tounderstand more about what he or she isobserving, or what they should be looking for.Clicking on this button launches a new browserwindow with one of WW2010’s helper pages. Anexample helper page is shown in Figure 3. Thecurrent weather map is placed side-by-side withan example map and descriptive text below. Thetext instructs the user about potential features tolook for. The example is described briefly in thetext, and the current image is shown next to it sothe student can see if there are similar features atthe present time. In short, clickable access fromreal-time weather maps to the helper pages allows
Figure 3. Example current weather producthelper page
instructors and students easy access to thedefinitions, explanations, and examples they need.
4.2 Learning Modules Linked to Products
However, even more useful -- and uniqueto WW2010 -- is the ability to provide weatherproducts as real-world examples linked to theinstructional materials. Scattered throughout theWW2010 educational material on relevant pages,there are markers in the navigation menu (Figure4, bottom left). Upon clicking these markers, a newbrowser window opens with the relevant weatherproduct inside. For example, on a page thatdiscusses how infrared satellite images areinterpreted, one click can present the latestinfrared satellite image on the screen.

5. APPLICABILITY TO THE WW2010 CD-ROM
This new technology is still compatiblewith our already existing CD-ROM. Students canaccess the current weather from their CD-ROMover the Internet, and return to the local computerfor information and insight into the weatherproducts. At all times, a user of the CD-ROM willhave the ability to access the instructional pageson these weather products from their local disk.
6. FUTURE WORK
Future plans include building a currentweather example section that will provide simplepages of recent weather in the news – accessible
also from relevant educational pages. This givesstudents the ability to cognitively translatebetween educational topics and current events,such as hurricanes and severe storms.
Future work is also intended to create aninteractive environment where teachers andstudents would be able to customize and createtheir own weather maps. This environment wouldpossess the same ability to link to WW2010educational helper pages that the current weatherproducts have. This highly interactive environmentwill provide the learner with an even more hands-on approach to viewing weather maps.
7. CONCLUSION
The combination of WW2010’s previouslyexisting educational framework and the newcurrent weather products will increase thelearner’s level of understanding in the atmosphericsciences. This integration will be effective inclassroom and laboratory settings within universityintroductory level courses and laboratories, as wellas to others interested in learning more about thescience behind the weather maps.
