DataSheet_1_Spatio-temporal variability of surface turbulent heat flux feedback for mesoscale sea surface temperature anomaly in the global ocean.docx
The surface turbulent heat flux feedback α T plays an important role in the atmosphere–ocean coupling. However, spatio-temporal variability of α T for sea surface temperature anomaly (SSTA) at oceanic mesoscales in the global ocean remains poorly assessed. In this study, we tackle this issue using a...

The surface turbulent heat flux feedback α T plays an important role in the atmosphere–ocean coupling.
