第9题
Conventional computer models of the atmosphere have limited value in predicting short lived local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to study carefully the subtle atmospheric changes that come before these storms.In most nations, for example, weather – balloon 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 events.
Until recently, the observation intensive approach needed for accurate, very short – range forecasts, or “Nowcasts,” was not feasible.The cost of equipping and operating many thousands of conventional weather stations was extremely high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were hard to overcome.Fortunately, scientific and technological advances have overcome most of these problems.Radar systems, automated weather instruments, and satellites are all capable of making detailed, nearly continuous observation over large regions at a relatively low cost.Communications satellites can transmit data around the world cheaply and instantaneously, and modern computers can quickly compile and analyze this large volume of weather information.Meteorologists and computer scientists now work together to design computer 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 becoming a reality.
11.The word “exceeded” in paragraph I most probably means ____________.
A.added up toB.were more than

12.Conventional computer models of the atmosphere fails to predict such a short – lived tornado because ______________.
A.the computer is not used to forecast specific local events
B.the computers are not advanced enough to predict it
C.the weather data people collect are often wrong
D.weather conditions in some small regions are not available
13.According to the passage, the word “Nowcast” (paragraph 3) means _______________.
A.a way of collecting raw weather data
B.a forecast which can predict the weather conditions in the small area in an accurate way
C.a network to collect instant weather data
D.a more advanced system of weather observation
14.According to the passage, ___________ is the key factor to making “Nowcasts” a reality.
A.scientific and technological advances such as radar, or satellites
B.computer scientist
C.meteorologists
D.advanced computer programs
15.According to the author, the passage mainly deals with ________________.
A.a tornado in Edmonton, Alberta

C.the disadvantage of conventional computer models of the weather forecast
D.a breakthrough in weather forecast
