HRD Seminar – Dr. Altug Aksoy (CIMAS/HRD) – 3 March 2020

Dr. Aksoy presented a seminar titled “Assimilation of Coyote UAS Observations in Hurricane Maria (2017): Optimization of Data Impact”. ABSTRACT The Coyote is a low-altitude small unmanned aircraft system (sUAS) that is air-launched from the NOAA WP-3D (P-3) hurricane hunter aircraft through its existing standard A-size sonobuoy launch capability. Its meteorological sensors directly measure temperature, … Continue reading HRD Seminar – Dr. Altug Aksoy (CIMAS/HRD) – 3 March 2020

Paper evaluating different schemes to predict convection in hurricanes released online in Weather and Forecasting

Forecasters and researchers use the Hurricane Weather Research and Forecasting (HWRF) model to forecast where a hurricane will go, how strong it will be, how large it will be, and where the strongest winds are. Hurricanes are made up of thunderstorms (what we call convection), but individual thunderstorms are too small for the models we … Continue reading Paper evaluating different schemes to predict convection in hurricanes released online in Weather and Forecasting

Paper on the intensification of tropical cyclones in wind shear published in Mausam

Hurricanes are fed by energy from the warm ocean. The center of a hurricane is surrounded by tall clouds, called cumulus clouds, that produce the heat needed to keep the spin, what we call vorticity, in the hurricanes going. When there are a lot of cumulus clouds around the hurricane's center, the hurricane spins more rapidly. However, … Continue reading Paper on the intensification of tropical cyclones in wind shear published in Mausam

AOML Flies Science Missions into Succession of Atlantic Storms

“Many of the storms we flew in 2019 were ‘living on the edge,’ in that they were weak, vertically sheared, but also unpredictable. In previous years, we saw these storms intensify, such as Hurricane Michael in 2018. This season, many struggled to intensify. As we continue to build a dataset of these sheared storms, we … Continue reading AOML Flies Science Missions into Succession of Atlantic Storms

HRD Seminar – Alrick Green, NERTO – San Jose State University – 12 November 2019

Alrick, participating in the NOAA Experiential Research and Training Opportunities (NERTO) program, presented a seminar titled “Understanding the Role of Eddy Vorticity Fluxes on the Rapid Intensification of Hurricane Irma (2017) and Michael (2018)”.  ABSTRACT The relationship between rapid intensification and environmental forcing is investigated for Hurricane Irma (2017) and Hurricane Michael (2018) using the … Continue reading HRD Seminar – Alrick Green, NERTO – San Jose State University – 12 November 2019

Hurricane Field Program Update — Thursday, October 17, 2019, 5pm EDT

We are planning two flights into Potential Tropical Cyclone 16 for Friday.  The first, with NOAA42, will depart Lakeland at 0800 EDT (1200 UTC) and perform a lawnmower pattern through and around the system The second, with NOAA43, will depart 12 hour later, and perform a butterfly pattern Both will return to Lakeland.  Both missions … Continue reading Hurricane Field Program Update — Thursday, October 17, 2019, 5pm EDT
