Abstract
The convective instability induces the phenomenon of spatial sensitivi ty to the boundary conditions. We introduce a quantity, the ''spatial' ' Lyapunov exponent, to characterize this kind of complex behavior, in nonchaotic but convectively unstable flow systems. Then we establish a relation between this spatial-complexity index and the comoving Lyap unov exponent.
