Vortrag
Homogeneous Ice Formation in Supercooled Water Clouds
11.07.2017, 15:00 - 16:00
KIT Campus Nord, IMK
Gebäude 435, Raum 2.05
 

It is important to know the phase and physical properties of aerosol and cloud particles at the top of high tropospheric clouds – anvils and the stratiform cirrus that originate from them – in order to better estimate their effects on energy balance, atmospheric moisture budget and regional circulation patterns. This talk revisits the formation of pristine ice crystals from homogeneous freezing of a population of cloud droplets - arguably the most basic liquid water-to-ice phase transition path in tropospheric clouds - by means of a theoretical analysis. Characteristic differences of the phase transition in different freezing-growth regimes will be illustrated by means of parcel simulations. Ramifications of these findings for the dynamical vs aerosol control of ice nucleation in cold cloud outflow regions are outlined.
