Abstract | Water stresses are occurring in Southeast Queensland. In order to assess the feasibility of any future precipitation enhancement potential in clouds in the Southeast Queensland region, it is extremely important to obtain observations in a well-designed measurement program. Aerosol and microphysical measurements, in particular, can help determine if seeding could be beneficial and also help determine what the optimal seeding method would be with regards to potential for enhancing precipitation in local clouds. The potential for such manmade increases is strongly dependent on the natural microphysics and dynamics of the clouds that are being seeded (in this case microphysics means the size and concentration of water droplets and ice inside clouds). These factors can differ significantly from one geographical region to another, as well as during and between seasons in the same region. In some instances, clouds may not be suitable for seeding, or the frequency of occurrence of suitable clouds may be too low to warrant the investment in a cloud seeding program. Both factors need to be evaluated from a climatological perspective. It is therefore important to conduct preliminary studies on the microphysics and dynamics of the naturally forming clouds prior to commencing a larger, operational experiment. It is also important to conduct hydrological studies relating rainfall with river flows and reservoir levels, and to determine hydrological regions where reservoir catchments are most efficient. Seeding could then be optimized by preferentially targeting the most efficient watersheds. The following is a summary of key preliminary results derived from the analysis of data collected during the 2007-2008 season in Southeast Queensland. |
