Review of how aircraft data are ingested into forecast models for tropical cyclones published in the Annals of the New York Academy of Science

This book chapter reviews how data are ingested into computer models and summarizes recent advances in how data relevant to tropical cyclones are used. Figure.  The impact of ingesting hurricane hunter data on predictions of storm intensity from NOAA’s state-of-the-art hurricane model, the Hurricane Weather Research and Forecast Model.  In this figure, the impact of … Continue reading Review of how aircraft data are ingested into forecast models for tropical cyclones published in the Annals of the New York Academy of Science

NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic

The NOAA flight season began early this year with an operational flight into a system, known as Potential Tropical Cyclone 2, that may soon develop into a tropical depression east of the Windward Islands. The plan for the season was recently released and is available online at https://www.aoml.noaa.gov/2022-hurricane-field-program/, and a kickoff meeting to discuss plans … Continue reading NOAA Hurricane Field Program begins with flights into Potential Tropical Cyclone 2 in the Tropical Atlantic

Study on the impact of weather data not transmitted in a timely manner published in Weather and Forecasting

We test how different groups of observations, which reach the computer that run weather models at different times, impact the model forecast. We find that by not using the observations that arrive late, the forecast is much worse, showing the importance of quick transmission of observations. Direct observations (those measured within the atmosphere) have a greater … Continue reading Study on the impact of weather data not transmitted in a timely manner published in Weather and Forecasting

HRD Monthly Science Meeting of March 2022

March’s science meeting consisted of four presentations by students of our collaborator Prof. Haiyan Zhang at Florida International University: Xinxi Wang: Relating Tropical Cyclone Intensification Rate and Inner-Core Features Using 16-yr TMI data Adrian Lopez: Defining Tropical Cyclone Rapid Intensification Using Bootstrapping Extreme Threshold Estimation  Oscar Guzman: Climatology of Tropical Cyclone Rainfall Magnitude at Different … Continue reading HRD Monthly Science Meeting of March 2022

Study on using neural networks to estimate tropical cyclone intensity using satellite imagery published in IEEE Transactions on Geoscience and Remote Sensing

The intensity of most tropical cyclones around the world are estimated by using satellite images. This study designed and evaluated convolutional neural network (CNN) models for estimating tropical cyclone intensity using geostationary satellite images. The selection of infrared channels was found to significantly affect the performance of these models. This work pointed out the best … Continue reading Study on using neural networks to estimate tropical cyclone intensity using satellite imagery published in IEEE Transactions on Geoscience and Remote Sensing

Every year, the Fall Meeting unites >25,000 attendees from 100+ countries in the Earth and space sciences community to discuss findings, connect scientists from around the world, advance the profession and connect over passion for the impact … Continue reading HRD scientists participate in the American Geophysical Union Fall Meeting 2021

Study on the impact of the new CYGNSS satellites on hurricane forecasts published in Monthly Weather Review

Part of the difficulty of forecasting tropical cyclone (TC) track and intensity (where the TC is going and how strong it will be) stems from the lack of frequent, accurate observations over tropical oceans where TCs form and develop. While Hurricane Hunter aircraft can collect vital observations in and near TCs, those observations are limited … Continue reading Study on the impact of the new CYGNSS satellites on hurricane forecasts published in Monthly Weather Review

Flights continue in Hurricane Ida

NOAA has so far completed five flights into and around Hurricane Ida as it crossed over the Cayman Islands and western Cuba toward its forecast landfall along the Louisiana coast. Two synoptic surveillance missions were conducted by the NOAA G-IV high-altitude aircraft to gather dropwindsonde and Doppler radar data around the hurricane to be ingested … Continue reading Flights continue in Hurricane Ida
