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.

?Read the article below about how to set up shop on the Internet.
?For each question 31—40, write one word in CAPITAL LETTERS on your Answer Sheet.
SETTING UP SHOP ON THE INTERNET
If you want to set up shop on the Internet, the first thing you will need to get started is, quite simply, SOMETHING to sell. You will need to find a supplier (31) a large inventory of wholesale items. The products have to be at a low enough cost that you can make a large profit margin (32) re-sale. Plus you will need a large variety of items to cover a wide range of your customers' needs and preferences (33) will keep them coming back by offering new items. Next you will need a professional looking website that will give your company (34) well established look and make your customers enjoy (35) experience at your website and will create an environment in which they will want to make purchases. It is also a good idea to accept credit card payments. With the development of secured orders forms, the majority of Internet customers want the convenience to be able to pay (36) their credit card rather than mailing a check (37) money order.
And finally, you will need the marketing strategies that will effectively show you how to bring new customers to your site, and keep them coming back as repeat customers. (38) this point, the World Wide Web is clearly unstoppable. The amount of sales exceeded $ 10 billion dollars last year and is predicted to steadily increase each year (39) thousands of Internet users are jumping on-line daily and making their purchases. You can be set up to accept their orders and claim (40) share of this multi-billion dollar a year market.
