New Data in Action: A Tale of Two Hurricanes in the Gulf of Mexico
A unique event was observed in the Gulf of Mexico - the occurrence of two tropical cyclones within close spatio-temporal proximity to one another and their combined ocean response.
Data in Action: A Tale of Two Hurricanes in the Gulf of Mexico
At the end of August 2020, a unique event was observed in the Gulf of Mexico - the occurrence of two tropical cyclones within close spatio-temporal proximity to one another and their combined ocean response. Marco made landfall first, as a tropical storm on 24 August 2020, having weakened from a Category 1 hurricane before landfall. Laura made landfall on 27 August 2020 as a Category 4 hurricane, having intensified from a Category 2 within 24 hours prior to landfall.
Animation: Sea Surface Temperature Response to Tropical Cyclones Laura and Marco (2020)
Evolution of the NASA Multi-Scale Ultra-High Resolution (MUR) sea surface temperature (SST) anomaly response to Tropical Cyclones Laura and Marco in 2020. It is common to observe trails of cooler water, or cold wakes, along hurricane tracks as a result of wind-induced mixing and turbulence that brings cold waters at depth to the surface. The cold wakes associated with Laura and Marco are clearly observed as waters approximately 2°C cooler from normal across the entire eastern Gulf of Mexico that persisted for several days.

Wind Speed from QuikSCAT Level 2B Version 4.1 dataset.
Animation: Wind Speed from QuikSCAT Level 2B V4.1
The QuikSCAT satellite/instrument launched on 19 June 1999 to retrieve ocean surface wind vectors calibrated to 10 meters above the ocean surface and provides 90% global coverage over the ice-free oceans, seas and large lakes when in full operating mode. Shown in this animation is wind speed from the QuikSCAT Level 2B Version 4.1 dataset (DOI: https://doi.org/10.5067/QSX12-L2B41) from 27 October 1999 to 22 November 2009.
