Extreme High Global Temperatures 140 Tirat Tsvi, Israel 32. winds have ever been recorded as high as those proposed by an F-6 rating. 4. Answers may vary. Students should label the x axis with the names of the regions. The y axis should show an adequate range of temperatures labeled in equal increments. Bars that represent the temperatures shown in the data table should be graphed. Death Valley, CA 24. 25. 26. 27. 28. 29. 30. 31. 1. approximately 100 mph 2. F-5 3. Answers may vary. Sample answer: No El Azizia, Libya 23. when precipitation will occur or the exact amount. They can manipulate data on temperature and pressure to simulate errors in measuring these data. Then they compare forecasts to see if slight data changes can cause substantial differences in forecasts. F C A D B G E Particles are added to clouds to cause the clouds to precipitate. In Russia, cloud seeding has been used with some success on potential hail clouds to produce rain rather than hail. Hurricanes have been seeded with freezing nuclei in an attempt to reduce the intensity of the storm. because it is not an attainable goal with current technology. by seeding potential lightning storms with silver-iodide nuclei Seeding potential lightning storms has seemed to modify the occurrence of lightning, but results have been inconclusive.
