Revisiting turbulent transport dissimilarities and coherent structure transitions: An observation study from subtropical paddy fields

• Turbulent transport dissimilarities are observed even on ideal underlying surfaces. • The dissimilarities are accompanied by the transitions of coherent structures. • Prevailing coherent structures and its role under each stability regime are depicted. Turbulent transport dissimilarities among momentum, heat, and passive scalars challenge the application of Monin-Obukhov similarity theory in land-atmosphere exchange parameterization, yet their intrinsic mechanisms remain insufficiently underst
