Extratropical cyclones dominate the weather and                            precipitation in temperate latitudes.  The precipitation pattern                is often organized in a banded structure.  The horizontal scales                of the frontal rainbands range from a few kilometers along the                  cold fronts to several tens of kilometers observed in both the                  warm and cold sectors of a frontal system.  Several theories                    have been put forward to explain the organization of frontal                    rainbands; presently the conditional symmetric instability                      appears capable of explaining several types of rainbands.  The                  most important next stage in the development of this subject is                 the implementation of conditional symmetric instability in                      numerical models.  Using the mesoscale model of the Pennsylvania                State University, Professors Warner and Clark will examine the                  model characteristics required of a realistic simulation of the                 rainband structures.                                                                 The bulk of the rainfall received in temperate latitudes is                associated with the passage of either warm or cold fronts. This                 work, when successfully  completed, represents an important step                forward in the numerical prediction of mesoscale precipitation.
