Observations of Supercooled Liquid Water over the Southern Ocean with a Digression on Cloud Seeding in Tasmania

Given by: Steve Siems, Monash University Abstract: The present generation of satellite products (CALIPSO, MODIS) has revealed the near-constant presence of supercooled liquid water (SLW) over the Southern Ocean. A climatology of these clouds has been developed using MODIS, CloudSat, CALIPSO and the merged data product DARDAR-MASK to reveal the dominance of boundary layer clouds across the region.  The thermodynamic structure of these clouds and the boundary layer has then been examined through the historical sounding records at Macquarie Island (54° S) to demonstrate the importance of wind shear through the region. Finally the historical cloud seeding projects across Tasmania and Southeast Australia are reviewed in light of these observations.
