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

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
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
