The atmospheric boundary layer is home to a number of horizontally elongated quasi-two-dimensional phenomena including cloud streets, roll vortices, thermal waves, and surface layer streaks. These phenomena, their dynamics, and their interactions are explored via a review of the literature. Making a clear distinction between the various quasi-two-dimensional phenomena allows improved synthesis of previous results and a better understanding of the interrelationships between phenomena.
