This article was posted in the site Scientific American which is a magazine published in 1845 and is the oldest continuously published magazine in the U.S. In this magazine, lots of nobel prize scientists have contributed articles. The article is written by Jane Lubchenco and Jack Hayes. As observed, the magazine is very well-known and prestigious, therefore the content in is valid.
The article starts off with an example of the Hurricane Joplin that hit the USA in 2011, it ended with 550 casualties. This hurricane was warned 20 minutes before it hit the USA. Now, tools for forecasting extreme weather have improved, and now extreme weather can be warned of an hour before it actually occurs, which gives the family enough time to prepare and take shelter. Radars are used to predict these extreme weathers and although the Doppler Radar does have flaws, it can distinguish a rainstorm from a dust storm. Forsyth, a meteorologist, has since focused on upgrading radars. One critical upgrade is called dual polarization. This technology allows forecasters to differentiate more confidently between types of precipitation and amount. The understanding of particle size helps to produce more accurate forecasts, so residents know they should prepare for hail and not rain, for example. This article is relevant to the topic we are studying because it shows how weather forecasting technology and its improvement can be the difference between life and death, as it gives people enough time to prepare for extreme weather.
