(5)On October 17, hurricane Gonzalo hit the island of Bermuda, knocking down trees and power lines, and making roads and streets impassable. The damage was substantial But thanks to early warnings from forecasters, residents were able to prepare and no deaths or serious injuries were reported.
    Scientists say weather systems are hard to predict because so many variables have to be taken into account. But increasingly complex calculation methods and accessibility to supercomputers are making weather prediction much easier.
    (6)Air pollution is another modern disaster that affects large cities and industrial areas. So its adverse effect on health also makes its timely measurement important. Even in cities that do not have pollution problems, it is important to measure other atmospheric conditions.
    University of Geneva research team leader said their new instrument uses an optical detector with radiation technology. (7)The device is highly specific and allows identification of different kind of particles in the atmosphere. We are able to detect and measure different species of flower powder in the real time. The Brussels exhibition, now in its fifth year, drew more than 2,500 people from around the world to see the latest weather and climate change forecasting technology.
