Abstract
Recent studies (Moore et al, 2016, Nature Physics, Moore et al., JGR 2017) have shown that during Kelvin-Helmholtz Instability ion-scale plasma waves are more abundant and are associated with ion heating. In the present paper the Kelvin-Helmholtz (KH) Waves within the flank magnetopause are identified in the Magnetosphere Multi Scale (MMS) data and are sorted with respect to the OMNI solar wind conditions. Large scale KH wave properties and current layer structures are compared with 3-D MHD simulations. A search for high frequency (between ion and electron scales) plasma waves in KH vortices is performed, waves are analyzed and the properties are compared with the ambient plasma characteristics
