Hurricane Field Program The Hurricane Field Program is a coordinated, multi-institutional series of field campaigns that conduct in situ and remote sensing research on tropical cyclones using aircraft, ships, buoys, radars, and satellites. Developed through partnerships among National Oceanic and Atmospheric Administration, National Aeronautics and Space Administration, university consortia (for example University of Miami, Florida State University, University of Washington), and military units (for example United States Air Force, United States Navy), the program supports operational forecasting centers such as the National Hurricane Center and research institutions such as the Woods Hole Oceanographic Institution and the Scripps Institution of Oceanography. Its campaigns integrate expertise from meteorologists, oceanographers, engineers, and data scientists to improve understanding of cyclone structure, intensification, track, and impacts.

Overview

Field campaigns under the program deploy diverse assets — including research aircraft like the Lockheed WP-3D Orion, unmanned systems such as General Atomics MQ-9 Reaper derivatives, shipborne platforms including NOAA Ship Ronald H. Brown, and coastal radar arrays like the National Weather Service WSR-88D network — to probe tropical cyclones across the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. Collaborations frequently involve international partners such as the Met Office, Météo-France, and the Japan Meteorological Agency. The program’s datasets feed into numerical weather prediction systems run at institutions including the European Centre for Medium-Range Weather Forecasts, the National Centers for Environmental Prediction, and research groups at universities such as Massachusetts Institute of Technology and Princeton University.

History and major campaigns

Early precursor efforts trace to post‑World War II reconnaissance by the United States Navy and United States Air Force that led to systematic operations like the Aircraft Reconnaissance Forensics era and later scientific campaigns. Notable organized campaigns include the Hurricane Rainband and Intensity Change Experiment, the Genesis and Rapid Intensification Processes (GRIP), the Hurricane Rainband and Intensity Experiment (HRIE), and the IFEX (Intense Hurricane Wind Field Experiment) collaborations. High-profile multiagency efforts such as Hurricane Field Program joint deployments with NASA airborne sensors during missions tied to satellite observatories (for example GOES-R and Aqua) advanced remote sensing synergy. International efforts, for instance collaborations with CIMSS and ECMWF partners during major seasons, expanded observational coverage and model intercomparison exercises.

Objectives and research methods

Primary objectives include diagnosing mechanisms of rapid intensification, quantifying air–sea exchange processes, characterizing inner-core dynamics, and improving track and intensity forecasts delivered to centers like the National Hurricane Center and Weather Prediction Center. Methodologies combine targeted in situ sampling (flight flight legs through eyewalls, dropsonde arrays), remote sensing (Doppler radar and synthetic aperture radar), and coordinated model assimilation experiments at centers including the NOAA Geophysical Fluid Dynamics Laboratory and NCAR (National Center for Atmospheric Research). Teams use experiment design principles refined from prior studies such as COAMPS-TC and HWRF evaluation campaigns, and leverage community tools developed at institutions like University Corporation for Atmospheric Research.

Instrumentation and platform types

Airborne platforms include turboprop research aircraft such as the Lockheed WP-3D Orion operated by NOAA and hurricane hunter aircraft from USAF wings. Remotely piloted systems derived from General Atomics designs carry microwave sounders, infrared imagers, and turbulence probes. Surface and ocean platforms range from shipboard Doppler radars on vessels like NOAA Ship Ronald H. Brown to moored buoys from the National Data Buoy Center and expendable bathythermograph arrays deployed by Naval Research Laboratory teams. Coastal and airborne radars include WSR-88D, X‑band portable radars from university groups (for example University of Oklahoma), and airborne Doppler radars such as those developed at NASA Wallops Flight Facility and NCAR.

Data collection, analysis, and models

Data streams include dropsonde profiles, airborne Doppler wind fields, surface flux measurements, and satellite radiances from platforms like Aqua and Suomi NPP. Collected observations are quality-controlled and ingested into data archives maintained by NOAA Central Library and research centers such as Roper Center and IRI. Analysis workflows utilize community codes and modeling systems including HWRF, GFS, ECMWFIFS, and high-resolution convection-permitting models at institutions such as NCAR and MIT. Researchers perform ensemble assimilation experiments, variational and ensemble Kalman filter studies, and process-level diagnostics to link observations to predictability metrics and parameterization development.

Operational impact and forecasting contributions

Findings from program campaigns have led to improved representation of eyewall replacement cycles in operational models like HWRF and contributed to enhancements in rapid intensification guidance used by the National Hurricane Center and regional forecast offices. Observational innovations (for example coordinated dropsonde arrays and airborne radar retrievals) influenced satellite assimilation at agencies such as NOAA and NASA and advanced guidance products at centers like CONUS regional forecast facilities and international forecast services including the Met Office. Program outputs support post-storm assessments conducted by entities such as the FEMA and academic impact studies at universities like Columbia University and Penn State University.

Safety, logistics, and coordination protocols

Safety and logistics are managed through interagency agreements among NOAA, NASA, USAF, US Navy, and academic partners, with mission planning coordinated by operational centers such as the National Hurricane Center and logistics units at Command and Control facilities and university flight operations offices. Protocols include aircraft safety standards from Federal Aviation Administration directives, shipboard procedures aligned with International Maritime Organization guidance, and airspace coordination with Federal Aviation Administration traffic control. Emergency response, medical evacuation planning, and payload certification follow institutional review boards and safety committees at organizations like NOAA Aeronautical Operations Center and university research safety offices.
