Why did scientist who study weather need more advanced technology

More advanced technologies will lead to better forecasts especially about extreme weather conditions. In this way, many lives can be saved if the timings for conditions such as hurricanes and tornadoes are foretasted before hand. New radar technology is required to which allows weather forecasters to have better knowledge about the extreme weathers. Scientists must get an advanced technology which allows data to be more precise so that even the speed of a hurricane or tornado can be measured.
