Last week, a team of intrepid storm chasers converged near Corpus Christi, Texas to witness the landfall of Hurricane Harvey, the storm that's brought over 127cm of rain to the Texas Gulf Coast and major flooding to the city of Houston. But these researchers collecting data for the National Oceanic and Atmospheric Administration (NOAA) didn't just get the usual storm readings. They obtained weather balloon data they say have never before been collected from a hurricane in the history of the agency. Eventually, they hope the information acquired will help improve forecast models and prevent future disasters such as the flooding in Houston.
