Improvements to the NOAA regional hurricane modeling system – HWRF
HRD Seminar – Dr. Jonathan Poterjoy, University of Maryland – 16 October 2018
Dr. Poterjoy presented a seminar titled “Regional Weather Prediction Using an 'Iterative' Local Particle Filter". ABSTRACT: Particle filters (PFs) are sequential Monte Carlo methods that can solve data assimilation problems characterized by non-Gaussian error distributions for prior model variables or measurements. From the perspective of a geoscientist, PFs contain several theoretical properties that make them … Continue reading HRD Seminar – Dr. Jonathan Poterjoy, University of Maryland – 16 October 2018
Hurricane Field Program Update – Wednesday, October 10, 2018
The NOAA P-3 completed its last mission into Hurricane Michael this morning, passing through the storm four times. As in the previous three missions, we provided critical measurements of the 3-D wind, precipitation, and thermodynamic (temperature and humidity) structure of the storm from our Doppler radar, dropsondes, and flight level measurements. The data was not … Continue reading Hurricane Field Program Update – Wednesday, October 10, 2018

HRD Seminar – Saiprasanth Balachandran, Purdue University – 5 September 2018
Mr. Balachandran presented a seminar titled “Spatial, temporal, and spectral characteristics of convective asymmetries driving rapid intensity changes in tropical cyclones”. ABSTRACT: Understanding the role of convective asymmetries in influencing a change in tropical cyclone (TC) intensity is a challenging task. The inherent difficulty is because asymmetries can arise from different sources, occur at different … Continue reading HRD Seminar – Saiprasanth Balachandran, Purdue University – 5 September 2018
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
