Sticky Issues in Turbulent Transport

We investigate the role of partial stickiness among particles or with a surface for turbulent transport. For former case, we re-derive known results case compressible Kraichnan model by using method based on bi-orthogonality expansion propagator in terms left and right eigenvectors. In particular, show that enforcing constraints orthogonality normalization yields were previously obtained rigorous, yet possibly less intuitive method. latter introduce general transport within atmospheric boundary layer. As suggested experimental observations tracers, both drift diffusivity scale height to ground. The strength is parameterized velocity V. use V range $$-1<V<0$$ $$0<V<1$$ there one-parameter family conditions are priori admissible. Outside range, single condition physical terms, parametrized degree which stick
