Hurricane Science Legend Dr. Robert Simpson Dies at Age 102

By: Dr. Jeff Masters, 11:29 PM GMT on December 19, 2014

Dr. Robert Simpson, one of the originators of the familiar Saffir-Simpson scale, passed away peacefully in his sleep today at the age of 102. Dr. Simpson began his meteorology career in 1940.

Updated: 5:45 AM GMT on December 17, 2014 Harnessing the Power of Crowd-Sourcing to Improve Hurricane Data

By: Dr. Jeff Masters, 6:16 PM GMT on December 12, 2014

Today's guest post is by Dr. Jim Kossin, a hurricane scientist with NOAA's National Climatic Data Center stationed at the University of Wisconsin/NOAA Cooperative Institute for Meteorological Satellite Studies (CIMSS). I flew with Jim in 1988 with the NOAA Hurricane Hunters into Hurricane Gilbert of 1988, when it was the strongest Atlantic hurricane ever measured--888 mb. Jim was just a graduate student at the time, and has gone on since to write over 70 scientific ...
