Short summary
In this work, we compute and analyze resolved gravity wave drag in high-resolution reanalysis data. Studying gravity waves with a realistic dataset helps us to understand them better and potentially improve climate projections. Part of our results supports a key hypothesis governing the vertical distribution of parameterized gravity wave drag in climate models; however, we also provide evidence of the strong influence of horizontal wave propagation, a mechanism that is currently missing in the models.
