Many of the most damaging and life-threating types of weather-torrential rains, severe thunderstorms, and tornadoes-begin quickly, strike suddenly, and dissipate rapidly, devastating small regions while leaving neighboring areas untouched. 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 computer models of the atmosphere have limited value in predicting short-live local storms like the Edmonton tornado, because the available weather data are generally not detailed enough to allow computers to discern the subtle atmospheric changes that precede 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 prohibitively high, and the difficulties involved in rapidly collecting and processing the raw weather data from such a network were insurmountable. 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 analyzing 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.

Đáp án B
Dịch nghĩa: Câu nào sau đây miêu tả chính xác nhất Nowcasting?
A. Một dự báo thời tiết cho 5 ngày
B. Cảnh báo về một cơn bão nghiêm trọng trên đài
C. Lượng mưa trung bình mỗi tháng
D. Một danh sách nhiệt độ ở những thành phố lớn
Giải thích: Ta thấy tác giả nói về Nowcast: “the observation-intensive approach needed for accurate, very short range forecasts, or “Nowcasts”, was not feasible” - “cách dự báo bằng quan sát cần thiết cho dự báo chính xác, rất ngắn ngày, hay Nowcast, không còn khả thi”
=> Trong các phương án thì B là ngắn ngày nhất.
