Abstract:

The phenomenon of the rapid growth and development of an extratropical cyclone over the east coast of the United States the Carolinas storm of March 1984 is studied through a linear stability analysis. Analyses of the cyclone structure suggest barotropic and baroclinic instabilities may be important. A linear stability model is used to investigate the roles and relative importance of shortwave baroclinic instability and barotropic instability in the growth and development of the storm. The growth rates, phase speeds and structure obtained from the linear model are consistent with those derived from observations. Energy budget results indicate that the vertical and horizontal barotropic terms are at least as important as the baroclinic term. It appears that the early growth and development of the cyclone can be explained through the contributions of barotropic and baroclinic instabilities without including convection. Keywords Linear stability analysis Baroclinic and barotropic instabilities explain behavior of one cyclone Theses.
