One such event, a tornado, struck the northeastern section of Edmonton, Alberta, in July 1987. Total damages from the tornado exceeded $ 250 million, the highest ever for any Canadian storm. Conventional puter models of the atmosphere have limited value in predicting shortlived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow puters to discern the subtle atmospheric changes that precede these storms. In most nations, for example, weatherballoon observations are taken just once every twelve hours at locations typically separated by hundreds of miles. With such limited data, conventional forecasting models do a much better job predicting general weather conditions over large regions than they do forecasting specific local recently, the observation—— intensive approach needed for accurate, very shortrange forecasts, or“ Nowcast, was not feasible. The cost of equipping and operating many thousands of conventional weather stations was prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a work were insurmountable. Fortunately, scientific and technological advances have overe most of these problems. Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observations over large regions at a relatively low cost. Communications satellites can transmit data around the world cheaply and instantaneously, and modern puters can quickly pile and analyze this large volume of weather information. Meteorologists and puter scientists now work together to design puter programs and video equipment capable of transforming raw weather data into words, symbols, and vivid graphic displays that forecasters can interpret easily and quickly. As meteorologists have begun using these new technologies in weather forecasting offices, Nowcasting is being a reality. author mentions the tornado in Edmonton, Canada, in order to .A. indicate that tornadoes are mon in the summerB. give an example of a damaging stormC. explain different types of weatherD. show that tornadoes occur frequently in Canada 32.
