Braving the Eye of the Storm: Research from drone penetration of hurricane eyewall published

Braving the Eye of the Storm Research from drone penetration of hurricane eyewall published The most dangerous part of the hurricane is the eye-wall close to the ocean. It’s where the storm draws energy from heat in the water, which influences how strong – and how quickly – the storm will develop. It’s also where … Continue reading Braving the Eye of the Storm: Research from drone penetration of hurricane eyewall published

New paper on hurricane research with drones highlighted in UCAR/NCAR news

A new paper by a team of scientists, led by the National Oceanic and Atmospheric Administration (NOAA) and National Center for Atmospheric Research (NCAR), demonstrates that observations just above the surface of the ocean near the eyewall of the storm can improve the performance of hurricane models used by forecasters. Scientists in 2017 and 2018 … Continue reading New paper on hurricane research with drones highlighted in UCAR/NCAR news

2019 Hurricane Field Program Season in Review and Hotwash, 13 November 2019

The purpose of the season review and "hotwash" is to review the highlights from the season and discuss what went right / what went wrong / and what could be done better in the future with respect to Hurricane Field Program operations/plans/logistics, as well as provide feedback to AOC about the aircraft and their operations. … Continue reading 2019 Hurricane Field Program Season in Review and Hotwash, 13 November 2019

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
