Hurricane scientists at AOML provided guidance and data support for National Hurricane Center (NHC) and Environmental Modeling Center (EMC) tasked reconnaissance into Hurricane Laura, identifying critical information about the system’s location, development, and intensification. Beginning on August 20th, 11 P-3 and 6 G-IV missions were conducted, capturing the complex lifecycle of Laura until its eventual … Continue reading AOML reviews science conducted during Hurricane Hunter missions into Laura
A recent paper in The Journal of the Atmospheric Sciences using ground-based radar and radar aboard NOAA P3 Hurricane Hunter aircraft brings new insight to the eyewall replacement cycle, a process by which an outer eyewall forms, contracts, and replaces the older, inner eyewall. During these cycles, the intensity and location of the strongest winds … Continue reading Article on the eyewall replacement cycle in Hurricane Matthew (2016) highlighted as a Paper of Note in the Bulletin of the American Meteorological Society

When the wind within about 150 miles of the center of a tropical cyclone (what we call the near environment) is very different at the bottom and the top of the storm (what we call wind shear), the storm usually weakens, especially if the storm is already weak. However, sometimes this doesn't happen, and the … Continue reading Paper on how tropical cyclones can intensify in high shear published in Monthly Weather Review
HRD researchers discussed the results from the 15 P-3 and 10 G-IV missions into Hurricane Dorian, AL05 (26 August - 5 September 2019). The format of the debrief was different than in the past. A brief overview is provided of the storm and missions, followed by a series of 8 short presentations discussing planned and … Continue reading HRD Debrief for missions into Hurricane Dorian – 30 January 2020
Summary: Accurate forecasts of hurricane strength are necessary to protect people in the path of a storm. The strongest winds in a hurricane are found near the center of the storm, in a ring of dangerous weather called the eyewall. As a hurricane grows older, it is common for the eyewall to eventually weaken and get … Continue reading Paper on the unusual eyewall replacement cycles in Hurricane Irma published in Monthly Weather Review
February’s science meeting consisted of four presentations: Paul Reasor - "Estimating Wind Radii from Tail Doppler Radar" John Kaplan - "Gust Factor Distributions in Hurricanes Harvey and Irma, a Preliminary Analysis Michael Fischer - "Characteristics of Tropical Cyclone Rapid Intensification Events in Environments of Upper-Tropospheric Troughs" Xiaomin Chen - "Structural Changes Leading to Rapid Intensification … Continue reading HRD Monthly Science Meeting of February 2019
Prof. Didlake presented a seminar titled “Asymmetric aspects of secondary eyewall formation in tropical cyclones”. A recording of the presentation is available on the anonymous ftp site: ftp://ftp.aoml.noaa.gov/hrd/pub/blog/seminars/2019/Didlake_HRD_Seminar_20190211.mp4

The purpose of the observation team meetings is to bring together the people who use observations in their research on a regular basis to discuss issues they’re having, provide updates on observations they’re analyzing or collecting, and any other information that may be of interest to the broader group. These meetings are also an excellent … Continue reading HRD observation team monthly meeting – 16 August 2018
