If I understand the military designation correctly they are the 53rd Weather Reconnaissance Squadron of the 403rd Wing of the Air Force Reserve (403rd Wing home page and on Facebook).
The C-130 Hurricane Hunter has a crew of five: two Pilots, a Navigator, an Aerial Reconnaissance Weather Officer, and a Weather Loadmaster/Dropsonde Systems Operator, go to the Hurricane Hunter Associations “People” Page for a description of what each crew member does.
Join Meteorologist Chrissy Warrilow with Georgia Public Broadcast on a tour of one of the USAF 53rd Weather Reconnaissance Squadron’s C-130 Hurricane Hunter aircraft. She had an opportunity to tour this C-130 Hurricane Hunter when the aircraft was visiting Georgia on a tour. You will hear Captain Tina Smith, Aerial Reconnaissance Weather Officer discuss the plane and the mission. Master Sergeant Amy Lee, the Load Master/Dropsonde Officer talks about how the Dropsonde is deployed and the types of data it records. You will also meet the pilot, Lieutenant Jarod Hamblin, and Dan Darbe a NWS Forecaster. The video was published on Youtube in February 2012.
