• The RAMS mesoscale model has been used to simulate the decay of a left moving supercell. The results show that the decay was due to the ingestion of negatively buoyant downdraft air. This decay process is different than that described by Rotunno and Klemp (1982). The first draft of a manuscript for publication in the Journal of Atmospheric Science is ready to be submitted.

• The RAMS model was used to show that dryline formation may at times be influenced by soil moisture values.  A simulation was conducted to show that the development of deep convection on the dryline can depend entirely on the values of soil moisture.
