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

Michael Black’s ashes released into Hurricane Michael

On July 14, 2017, AOML was saddened by the loss of Michael Black, a long-term research meteorologist with the Hurricane Research Division (HRD). Michael passed away unexpectedly at 62 years of age. He was a valued friend and colleague whose pioneering research on Doppler radar and the use of Global Positioning System (GPS) dropsondes paved … Continue reading Michael Black’s ashes released into Hurricane Michael

Paper on the Doppler Wind Lidar, a new instrument to measure wind from hurricane hunter aircraft, published in the journal Sensors

Summary: A new instrument, called an airborne Doppler Wind Lidar (ADWL, for short), was flown on NOAA’s hurricane hunter aircraft into two storms during 2016. This instrument measures winds above and below the plane. The ADWL measures wind where radar on the aircraft cannot: the radar can measure the wind where there are clouds or … Continue reading Paper on the Doppler Wind Lidar, a new instrument to measure wind from hurricane hunter aircraft, published in the journal Sensors

HRD Seminar – Dr. Yair Cohen, California Institute of Technology – 13 November 2018

Dr. Cohen presented a seminar titled “Gradient Non-Balance: A new approach for the outflow at the top of Tropical Cyclones: Theory, models and observations". ABSTRACT: The gradient non-balance is a flow-regime in which the gradient wind balance has no solutions or a given pressure map. This occurs only around a high pressure center, when the … Continue reading HRD Seminar – Dr. Yair Cohen, California Institute of Technology – 13 November 2018
