Abstract
Abstract An anomaly model linearized around the observed winter climatology is used to study the steady response of the atmosphere to diabatic heating. The model is an R7, nine vertical levels, primitive equations, fully spectral model, derived from the GFDL GCM (Geophysical Fluid Dynamics Laboratory's General Circulation Model). The anomaly model is capable of treating basic states that depend on latitude, longitude and height. The Krylov technique is used to solve the linear equations. This generality allows the treatment of the important problem of linear waves in the atmosphere from a more general paint of view; a larger class (zonally asymmetric) of basic states can now be treated for the baroclinic primitive equations. The (R7) linear anomaly model is used to investigate the linear response to equatorial and midlatitude prescribed heating. The results indicate that the solution is affected by the presence of the stationary waves in the basic state. In particular, in the case of midlatitude heating l...
