WebbAbstract. When orographic gravity waves (OGWs) break, they dissipate their momentum and energy and thereby influ-ence the thermal and dynamical structure of the atmosphere. This OGW forcing mainly takes place in the middle atmo-sphere. It is zonally asymmetric and strongly intermittent. So-called “OGW hotspot regions” have been shown to ex- WebbJournal of Geophysical Research: Atmospheres Volume 122, Issue 21p. 11,301-11,312 Research Article Free Access Impacts of Horizontal Propagation of Orographic Gravity Waves on the Wave Drag in the Stratosphere and Lower Mesosphere Xin Xu, Xin Xu orcid.org/0000-0002-4495-3677 tahmeed customer care number
