HRD Seminar – Dr. Andrew Hazelton (CIMAS/HRD) – 9 February 2022

Dr. Hazelton presented a seminar titled “Examining Hurricane Dorian's Early Intensification and Long-term Track Evolution Through an Ensemble of the Hurricane Analysis and Forecast System”. ABSTRACT: Hurricane Dorian (2019) was one of the strongest hurricanes on record in the Atlantic basin, and caused significant devastation across the northern Bahamas as it stalled out as a … Continue reading HRD Seminar – Dr. Andrew Hazelton (CIMAS/HRD) – 9 February 2022

Study on the best way to improve forecasts using a proposed satellite-based Doppler Wind Lidar published in Monthly Weather Review

This study investigates how to get the largest improvements to tropical cyclone forecasts from wind profiles obtained from a proposed new instrument, a Doppler Wind Lidar, on polar-orbiting satellites.  Wind profiles have the largest impact when the tropical cyclone’s structure was changing rapidly and when the measurements were taken close to the tropical cyclone center. … Continue reading Study on the best way to improve forecasts using a proposed satellite-based Doppler Wind Lidar published in Monthly Weather Review

Study on improving flight tracks to optimally improve winter-storm forecasts published in Meteorological Applications

A new study published in Meteorological Applications finds that changes in the flight track patterns of aircraft flying into storms to collect observations for weather forecast models could positively impact forecasts. Differences in where data is collected within a storm changes the model forecast. NASA’s Global Hawk, uncrewed aerial system. Image Credit: NOAA. The largest impact could … Continue reading Study on improving flight tracks to optimally improve winter-storm forecasts published in Meteorological Applications

Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications

Summary: The Global Hawk, a drone or uncrewed aircraft system, has been used since 2010 to gather data to improve weather forecasts. The Global Hawk can release dropsondes that measure temperature, pressure, humidity, and wind up to four times every second, starting at an altitude of up to 60,000 feet until it falls to the … Continue reading Paper on the optimal way to gather observations to improve winter-storm forecasts published in Meteorological Applications

Hurricane Hunter flights continue into Sally and Teddy

NOAA's P-3 aircraft wrapped up their sequence of missions into Hurricane Sally prior to the system's eventual landfall along the central Gulf Coast. Tasked by the National Hurricane Center (NHC), its final flight took off on September 15 at 9:30 EDT from Lakeland, FL.  Hurricane scientists supporting P-3 missions into Hurricane Sally identified the location … Continue reading Hurricane Hunter flights continue into Sally and Teddy

AOML Scientists Evaluate the Potential for Research in Tropical Storm Paulette

Each day hurricane scientists meet to discuss the viability of systems and the logistics needed to complete possible research goals.  In today's meeting, on Wednesday September 9, the scientists decided to wait one more day before making a decision to deploy to St. Croix or hold off for future opportunities.  Tropical Atlantic view from GOES-East showing … Continue reading AOML Scientists Evaluate the Potential for Research in Tropical Storm Paulette

AOML reviews science conducted during Hurricane Hunter missions into Laura

Hurricane scientists at AOML provided guidance and data support for National Hurricane Center (NHC) and Environmental Modeling Center (EMC) tasked reconnaissance into Hurricane Laura, identifying critical information about the system’s location, development, and intensification. Beginning on August 20th, 11 P-3 and 6 G-IV missions were conducted, capturing the complex lifecycle of Laura until its eventual … Continue reading AOML reviews science conducted during Hurricane Hunter missions into Laura

HRD Monthly Science Meeting of June 2020

June's science meeting consisted of six presentations: Jason Sippel: "Some thoughts about recent G-IV impact results" Sarah Ditchek: "Quantifying the Radial Impact of Dropsondes Using the Basin-Scale HWRF" Dave Nolan: "Evaluation of the Surface Wind Field Over Land in WRF Simulations of Hurricane Wilma (2005)" Lakemariam Worku: "Forecasting a Continuum Environmental Threats - Tropical Cyclone … Continue reading HRD Monthly Science Meeting of June 2020

Hurricane Field Program Update — Thursday, September 26, 2019, 5pm EDT

Both NOAA43 and NOAA49 are now in Barbados prepared for missions into Hurricane Lorenzo.  NOAA49 will conduct a NESDIS Satellite Validation and Diurnal Cycle Experiment, takeoff from Barbados 0800 AST/EDT (1200 UTC).  The goal is to sample the region around Lorenzo, including the Saharan Air Layer, and regions deemed sensitive to future forecasts.  There will … Continue reading Hurricane Field Program Update — Thursday, September 26, 2019, 5pm EDT

Hurricane Field Program Update — Tuesday, September 17, 2019, 10pm EDT

NOAA49 will conduct a mission in and around Tropical Depression 10, departing Barbados at 0900 local time (1300 UTC), and returning there about 8 hours later.  The aircraft will perform a lawnmower pattern to sample the environment and a circumnavigation of the system about 120 n mi from the center.  The goal is to sample … Continue reading Hurricane Field Program Update — Tuesday, September 17, 2019, 10pm EDT
