By introducing a compactness lemma and considering a constrained variational problem,
we obtain a set 
of steady waves for Hasegawa-Mima equation, which describes the motion of drift waves
in plasma. Moreover, we prove that 
is a stable set for the initial value problem of the equation, in the sense that
a solution 
which starts near 
will remain near it for all time.
