Scientists may soon be using GPS tracking technology to monitor and track hurricanes, according to a recent report published in Radio Journal. By utilizing a GPS tracking receiver in hurricane hunter aircrafts to measure disruptions in the sea and then comparing the data to that which is received from GPS tracking satellites, scientists can determine the strength of a storm, including wind speeds accurate within 11 mph. Using GPS tracking systems to track hurricanes may also be more cost effective than dropsondes, tubes containing scientific measuring devices dropped from planes directly into hurricanes, which cost more than $700 dollars each. However, GPS tracking for hurricanes is only effective for hurricanes at sea, not those which have already made landfall, and is somewhat less accurate than current methods.
