- Abstract
- <jats:p>Vertical ascent due to gravity waves (GW) represents one important formation mechanism for cirrus clouds, i.e., clouds consisting solelyof ice crystals. Further, GWs can substantially influence the microphysical cloud properties and cloud life cycle, which are crucialfor the radiative impact of the cirrus clouds. Here we investigate the interactions between high-, mid- or low-frequency GWs and cirrusclouds in the tropopause region. Utilizing asymptotic analysis reduced equations are derived for the self-consistent description of thecirrus dynamics forced by a monochromatic GW. This allows for the construction of prototype parameterization of the number nucleated icecrystals. The GW-cirrus interactions are studied further in cloud resolving large eddy simulation and the results are used to evaluatethe asymptotic parameterization.</jats:p>
