Hurricane Laura

On August 26, 2020, DOWs 7 and 8 deployed on Hurricane Laura as it made landfall near the Texas-Louisiana border as a category 4 storm. The story of the deployment was recently featured in the Washington Post (link). Below is a slideshow of some of our pictures and radar imagery from the mission.

Eye moving away from Lake Charles. Left panel is reflectivity; Right panel is Doppler velocity in m/s.
Eye moving away from Lake Charles. Inner eyewall ~15 km to the northeast. Note the finescale structures along the inner edge of the eyewall. Left panel is reflectivity; Right panel is Doppler velocity in m/s.

Wind streaks impacting the DOW7 radar location. The peak 1-second just was 49.6 m/s at ~8 m above DOW level (ADL). Doppler velocity in m/s is shown.
Wind streaks impacting the DOW8 radar location, deployed near the radius of maximum winds (RMW). The edge of the eyewall precipitation was ~10 km east of their location. Doppler velocity in m/s is shown.
