It has been known for some time that mesoscale                              convective systems in the tropics may develop rotational                        circulations of sufficient strength that the systems                            transform into tropical cyclones.  More recently, mid-                          latitude mesoscale systems have been shown to form                              mesoscale vortices which outlive their parent mesoscale                         convective system.  It also has been established that these                     mesoscale vortices can have significant impacts on the                          location, timing and severity of subsequent convective                          weather.  Due to their relatively small size and amplitude,                     mesoscale vortices typically are not sensed by the current                      operational weather system and the important physical                           processes are not well understood and, therefore, not                           accounted for in operational prediction models.                                     Using a state-of-the-art mesoscale model, the Principal                     Investigator will perform a series of numerical simulations                     of the formation of mesoscale vortices in both mid-latitude                     continental and tropical maritime regimes.  Results will                        lead to increased understanding of the physical processes by                    which mesoscale convective systems initially develop                            rotational circulations.  This understanding may lead to                        significant improvements in our ability to forecast                             convective weather systems and their attendant severe                           weather such as heavy rainfall, hail, high winds and                            tornadoes.
