Query: Nonperturbative Effects in QCD at $T>0$   The background field formalism is used to implement nonperturbative QCD
contributions into diagrammatic technic at $T>0$. The leading terms both in the
confining and nonconfining phase are identified at large $N_c$ and the
transition temperature is calculated in this limit, which appears to be in good
agreement with the Monte Carlo calculations.
