Zusammenfassung: | [...]of this, references made about the location of a dryline relative to other processes, such as the development of thunderstorms, may vary from one study to the next. The following features of the model were used. * Prognostic variables are the three components of momentum, u, v, and w, perturbation Exner function p*, total water rt , and ice-liquid potential temperature uil (Tripoli and Cotton 1981, 1982, 1989a,b).\n First was the thermally driven solenoids that aided in the eastward acceleration of the winds at the dry side of the dryline. The second process was frontogenetic forcing of the water vapor field superimposed on the convergent wind field within the lowest 1000 m. Future work will address how the magnitude and horizontal variations of soil moisture influence the lowlevel pressure field, solenoids, and frontogenesis along the dryline. |
