Coevolving aerodynamic and impact ripples on Earth
Hezi Yizhaq, Katharina Tholen, Lior Saban +11
Windblown sand creates multiscale bedforms on Earth, Mars, and other planetary bodies. According to conventional wisdom, decameter-scale dunes and decimeter-scale ripples emerge vi…
Megaripple mechanics: bimodal transport ingrained in bimodal sands
Katharina Tholen, Thomas Pähtz, Hezi Yizhaq +2
Aeolian sand transport is a major process shaping landscapes on Earth and on diverse celestial bodies. Conditions favoring bimodal sand transport, with fine-grain saltation driving…
The diurnal cycle and temporal trends of surface winds
Yosef Ashkenazy, Hezi Yizhaq
Winds play an essential role in the climate system. In this study, we analyze the global pattern of the diurnal cycle of surface (10 m) winds from the ERA5 reanalysis data. We find…
Spatiotemporal dynamics of biocrust and vegetation on sand dunes
Hezi Yizhaq, Yosef Ashkenazy
We propose a model to study the spatiotemporal dynamics of biocrust and vegetation cover on sand dunes. The model consists of two coupled partial nonlinear differential equations a…
Effects of quenched disorder on critical transitions in pattern-forming systems
Hezi Yizhaq, Golan Bel
Critical transitions are of great interest to scientists in many fields. Most knowledge about these transitions comes from systems exhibiting the multistability of spatially unifor…
Regime shifts in models of dryland vegetation
Yuval R. Zelnik, Shai Kinast, Hezi Yizhaq +2
Drylands are pattern-forming systems showing self-organized vegetation patchiness, multiplicity of stable states and fronts separating domains of alternative stable states. Pattern…
Biogenic crust dynamics on sand dunes
Shai Kinast, Ehud Meron, Hezi Yizhaq +1
Sand dunes are often covered by vegetation and biogenic crusts. Despite their significant role in dune stabilization, biogenic crusts have rarely been considered in studies of dune…
