[en] The selfconsistent description of the dipole excitations which uses the translational invariance principle for constructing the effective residual forces is generalized for the case of excited nuclei. The giant dipole resonance theory is developed in the thermodynamical random phase approximation. The theory does not contain any additional parameters besides those in the shell model potential. The temperature dependence of the strength parameters for the isoscalar and isovector forces, as well as of the differential and integrated characteristics of the giant dipole resonance is studied. The importance of the selfconsistency is shown for the description of the integral width of the resonance and for the spectral distribution of the ''low-energy'' gamma transitions
