2022 Saildrone Atlantic Hurricane Mission

Saildrone dockside awaiting launch

Seven saildrones are being deployed in the western Atlantic, Caribbean, and Gulf of Mexico during the 2022 Atlantic hurricane season, following the success of the experimental 2021 mission.

Keep up with the progress of the 2022 mission on the blog.

Objectives

(1) Measure near-surface atmospheric and upper-ocean parameters to calculate energy and momentum fluxes between the atmosphere and ocean outside and within hurricanes.

(2) Synchronize the deployments of saildrones and other uncrewed systems (ocean gliders, airdrones) and conventional assets (moored buoys, airborne atmospheric dropsondes and oceanic profilers) to measure the air-sea transition zone (upper ocean, air-sea interface, and marine atmospheric boundary layer).

(3) Transmit data in real-time to operational weather prediction centers to improve atmosphere-ocean initial conditions in forecast models.

(4) Apply the observations to understand how air-sea interaction affects hurricane intensity and to advance hurricane prediction models.

Deployments

Saildrone observations will cover August 1-October 30, 2022 in seven areas (highlighted by blue boxes in the map below) where chances of hurricane occurrence are high. Observations will be sent to worldwide weather prediction centers in real time to assist their operational forecasts. Data will be released for public use in near real time. This project also involves partnerships with NOAA's Environmental Modeling Center (EMC) of the National Weather Service and the CoastWatch of NOAA's National Environmental Satellite and Data Information Service (NESDIS).

Map of areas where saildrones are deployed with glider tracks

The blue boxes are planned saildrone observation areas. The green lines are planned ocean glider tracks. The background colors are probabilities of tropical storm-force winds within a 200 km radius during August-October. The dots mark the launch locations for saildrones (blue) and gliders (green). The pink contour shows the 50 cm/s isopleth of surface current speed on 15 September 2021.
