Abstract: Thermal equilibrium curves characterising the stability of warm absorbers 
in AGN have been studied for different ionising continuum shapes and chemical 
abundances using CLOUDY. Nature of this curve is affected by a number of factors 
particularly the dielectronic recombination coefficients. The absorber can have
 continuous pressure distribution or multiphase nature.
