Mega ripples have a mathematical pattern capable of “predicting” their behavior
Mega ripples appear to have a mathematical pattern capable of providing clues about a planet’s atmospheric conditions. An international study, led by Leipzig University, believes that the discovery could improve the ability to assess remote climate events from these sediments.
In order for dunes to form, all that is needed is sand on the surface of a planet and, of course, an atmosphere to produce the wind that shapes this landscape. Sand waves ranging from 30 cm to several meters in height are known as mega ripples, structures observed on both Earth and Mars.
It has long been known that the sizes of the grains involved in these ripples influence their shapes, which are never the same — much less the winds that push them. Now, the new study has …
