Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review

Summary: During each hurricane season, NOAA’s Gulfstream-IV (G-IV) Hurricane Hunter aircraft measures wind, temperature, humidity, and pressure in and around hurricanes threatening the United States.  An instrument called the dropwindsonde is released from the G-IV to collect the data as it falls to the ocean surface.  The plane currently flies where we expect observations from the … Continue reading Paper on getting the best TC forecasts using NOAA’s G-IV released online in Monthly Weather Review

HRD Seminar – Dr. Chris Collimore, Joint Institute For Regional Earth System Science and Engineering, UCLA – 5 March 2019

Dr. Collimore presented a seminar titled “The Impact of High Aerosol Concentrations on Tropical Cyclone Formation". ABSTRACT: Prior studies have shown that high levels of aerosols in the environment of convective clouds can cause the convection to become more vigorous through a five step process. Tropical cyclones (TCs) start as clusters of convective clouds and … Continue reading HRD Seminar – Dr. Chris Collimore, Joint Institute For Regional Earth System Science and Engineering, UCLA – 5 March 2019
