2. Institut für Physik der Atmosphäre 2 SPP 1167 Begutachtung, 10. Jan. 08, Bad Honnef LIFCOC is a proposal within the COPS bundle only project in PPL POLDIRAD only instrument to measure 4-d microphysics Its goal is: to study the complete life cycle of deep convection in mountainous terrain from initiation to decay It aims to answer the hypotheses and science questions of COPS and in particular the ones of the working group PPL: Location and timing of CI depends on the humidity (and wind) field Life cycle of single cells is affected by orography, but not the one of larger systems PPL 1: what is role of orography for the development of cells ? PPL 2: does the orography affect the hydrometeor distribution ? PPL 3: how does the RDSD change during the life cycle ?
