Sloshing action caused by storm events causes wavy and complexly cross-cutting layers in hummocky cross stratification. Changes in flow strength and direction result in heterolithic bedding and/or herringbone cross-bedding.

It is notably observed in sound, as with sirens, where frequency increases when approaching and decreases when moving away.
