'''LES of a cumulus cloud with explicit Lagrangian droplets''' \\ Responsible: In-Soo Kang \\ Project type: PhD project at the [http://gfdl.yonsei.ac.kr/ Department of Atmospheric Sciences], Yonsei University, Seoul, Yign Noh \\ Duration: 01/03/2005 -2007 \\\\ An LES model of a cumulus cloud is developed in which the motion of a large number of water droplets is explicitly simulated. The model provides various important information of the cloud process such as entrainment and internal mixing, the distribution of droplets within a cloud, and the evolution of particle size spectrum. A substantial part of this Korean PhD project is carried out visiting the PALM group in Hannover.
