Query: Shell Model for Time-correlated Random Advection of Passive Scalars   We study a minimal shell model for the advection of a passive scalar by a
Gaussian time correlated velocity field. The anomalous scaling properties of
the white noise limit are studied analytically. The effect of the time
correlations are investigated using perturbation theory around the white noise
limit and non-perturbatively by numerical integration. The time correlation of
the velocity field is seen to enhance the intermittency of the passive scalar.
