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

Scientists show the potential impact of the new and proposed COSMIC-2 satellites on weather forecasts in a paper released online in Weather and Forecasting

Summary:   The Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) are satellites launched in 2006 to orbit the earth about 500 miles above ground. They use radio signals from Global Positioning System satellites in a process called “radio occultation” to measure temperature and moisture with high accuracy and resolution. These data have proven … Continue reading Scientists show the potential impact of the new and proposed COSMIC-2 satellites on weather forecasts in a paper released online in Weather and Forecasting

Scientists show how Hurricane Edouard in 2014 rapidly intensified despite wind shear and dry air in paper released online in The Journal of the Atmospheric Sciences

Summary:  Tropical cyclones (TCs) usually weaken when there is a large change in the wind speed or direction with height (wind shear) or when there is dry air in the core.  Some TCs, like Hurricane Edouard (2014) can intensify, even rapidly, under these conditions. We use a series of model runs to understand how a … Continue reading Scientists show how Hurricane Edouard in 2014 rapidly intensified despite wind shear and dry air in paper released online in The Journal of the Atmospheric Sciences
