Chitre, S.M., and M.H. Gokhale, 1973: Convective instability in a compressible atmosphere. Sol. Phys., 30, 309-318, doi:10.1007/BF00152662.
The degree of convective instability as expressed by the growth rate ω of linear modes is calculated for a plane parallel polytropic atmosphere in the presence of radiative damping, withing using Boussinesq approximation. A comparison with the results based on the Boussinesq approximation reveals that the use of the Boussinesq approximation leads to and overestimation of the radiative damping. The computaton of ω as a function of the wave number yields a wavelength of maximal instability under a variety of conditions. For reasonable choices of physical parameters appropriate to the solar atmosphere, the fastest growing wavelengths turn out to be in the range 600-1200 km, and their e-folding times are in the range 200-2000 s.
