  Possibilities for formation of the charged pion field vortices in a rotating
empty vessel (in vacuum) and in the rotating pion gas with a dynamically fixed
particle number at zero temperature are studied within the $\lambda|\phi|^4$
model. It is shown that in the former case at a rapid rotation a supervortex of
a charged pion field can be formed. Important role played by the electric field
is demonstrated. Field configurations in presence and absence of the pion
self-interaction are found. Conditions for formation of the vortex lattice at
the rotation of the charged pion gas at zero temperature are studied.
Observational effects are discussed.
