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

Paper on measuring surface wind speed from hurricane hunter aircraft when it turns and rolls published in the Journal of Atmospheric and Oceanic Technology

Summary: The Stepped-Frequency Microwave Radiometer (SFMR) is an instrument flown on the NOAA and Air Force Hurricane Hunter aircraft that measures surface wind speed and how much rain is falling over the ocean in tropical cyclones.  Historically, the SFMR measurements have only been used when the aircraft is not turning or going up or down … Continue reading Paper on measuring surface wind speed from hurricane hunter aircraft when it turns and rolls published in the Journal of Atmospheric and Oceanic Technology

30th Anniversary of Hurricane Gilbert

On September 16, 1988, Hurricane Gilbert made landfall at the Mexican city of La Pesca,Tamaulipas, with winds of 125 mph (200 km/hr).  It had already brought destruction upon the Yucatan peninsula and the Caribbean islands.  Along the way it set a new low-pressure record that would stand for 17 years. Gilbert was a classic Cape … Continue reading 30th Anniversary of Hurricane Gilbert

HRD Seminar – Kyle Ahern, Florida State University – 4 September 2018

Mr. Ahern presented a seminar titled “Observed and Simulated Boundary Layer Structures in the Hurricane Inner-core During Intensity Change”. ABSTRACT: GPS dropwindsonde data from Atlantic basin aircraft reconnaissance missions (Hock and Franklin 1999) between 1998 and 2015 are gathered to construct composites of the hurricane inner-core boundary layer during modes of intensity change. Sounding information … Continue reading HRD Seminar – Kyle Ahern, Florida State University – 4 September 2018
