Education
COPS Science Hypotheses Upper tropospheric features play a significant but not decisive role for convectivescale QPF in moderate orographic terrain. (ETReC07, COPS, GOP) Accurate modeling of the orographic controls of convection is essential and only possible with advanced mesoscale models having a resolution of the order of a few kilometers (D-PHASE, COPS) Location and timing of CI depends critically on the structure of the humidity field in the planetary boundary layer (ARM, COPS, GOP) Continental and maritime aerosol type clouds develop differently over mountainous terrain leading to different intensities and distributions of precipitation (TRACKS, ARM, COPS) Novel instrumentation during COPS can be designed so that parameterizations of sub-grid scale processes in complex terrain can be improved (ALL) Real-time data assimilation of key prognostic variables such as water vapor and dynamics is routinely possible and leads to a significant better short-range QPF (COPS, GOP)

August 2007 Explosive cyclogenesis in southwestern France Convection, clouds, and precipitation imbedded in Saharian dust outbreak Measurements coordinated with ETReC07 Intense precipitation expected in COPS domain Global models agreed well with respect to timing and location of CI but deviated strongly in the forecasts of precipitation distribution in COPS area Impact of aerosols?

First Results of D-PHASE (Felix Ament, Meteo Swiss) Probably positive impact of 4DVAR with slant path GPS detected. Convection permitting models seem to simulate CI better, they reduce the windward/lee effect, however, potential by far not explored yet.
