      abstract     = {The spectral distribution in terms of horizontal and

                      momentum flux observations from space for the first time.
                      The paper focuses on High Resolution Dynamics Limb Sounder
                      (HIRDLS) observations in the subtropics and compares spectra
                      over particularly strong deep convective forcing with a
                      background inferred from regions of less momentum flux. The
                      deep convective spectra are strongly enhanced at high
                      horizontal wavenumbers over a wide range of vertical
                      wavenumbers and phase speeds. The observations indicate that
                      GWs generated by deep convection are an important
                      contribution on top of the background spectrum due to other
                      GW sources (at least about $20-30\%$ on zonal average is
                      from convective GWs). The implications for global modeling
                      are discussed. Citation: Ern, M., and P. Preusse (2012),
