  We study anomalous dissipation from a microscopic viewpoint. In the work by
Drivas, Elgindi, Iyer and Jeong (2022), the property of anomalous dissipation
provides the existence of non-unique weak solutions for a transport equation
with a singular velocity field. In this paper, we reconsider this solution in
terms of kinetic theory and clarify its microscopic property. Consequently,
energy loss can be expressed by non-vanishing microscopic advection.
