  In this note, we propose a discrete model to study one-dimensional transport
equations with non-local drift and supercritical dissipation. The inspiration
for our model is the equation $$ \theta_t + (H\theta) \theta_x
+(-\Delta)^\alpha \theta =0 $$ where $H$ is the Hilbert transform. For our
discrete model, we present blow-up results that are analogous to the known
results for the above equation. In addition, we will prove regularity for our
discrete model which suggests supercritical regularity in the range
$1/4<\alpha<1/2$ in the continuous setting.
