Abstract : The linear boundary layer solution (Chang, 1973b), which includes the temporal acceleration, is used for a CISK (Conditional Instability of the Second Kind) parameterization to study tropical lower tropospheric waves. A one-level equation is derived for the top of the boundary layer and is solved numerically for its eigenvalues. Calculations are made for varying boundary-layer depths and vertical heating gradients. Growth rates, periods and eigenfunctions for the lowest meridional modes of synoptic-scale disturbances are analyzed. Results indicate that CISK heating does not prefer any finite wavelength.
