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

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

Paper on the impact of new satellite wind velocity data on hurricane forecasts published in Monthly Weather Review

Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This … Continue reading Paper on the impact of new satellite wind velocity data on hurricane forecasts published in Monthly Weather Review

Paper on combining satellite data and data from the Global Hawk aircraft to improve forecasts published in Weather and Forecasting

Summary: Because satellites are observing the weather all the time, there are almost always satellite data available around hurricanes or tropical cyclones (TCs). On the other hand, Hurricane Hunter aircraft can only reach TCs when the storms are near land and when airplanes and crews are available. When Hurricane Hunter missions are planned, the regular … Continue reading Paper on combining satellite data and data from the Global Hawk aircraft to improve forecasts published in Weather and Forecasting
