Planetary boundary layer — Depiction of where the planetary boundary layer lies on a sunny day The planetary boundary layer (PBL), also known as the atmospheric boundary layer (ABL), is the lowest part of the atmosphere and its behavior is directly influenced by its… … Wikipedia
Ekman transport — Ekman transport, named for Vagn Walfrid Ekman, is the natural process by which wind causes movement of water near the ocean surface. Each layer of water in the ocean drags with it the layer beneath. Thus the movement of each layer of water is… … Wikipedia
Ekman layer — In standard boundary layer theory, the effects of viscous diffusion are usually balanced by convective inertia. When a fluid rotates, however, the dominant balance may instead be struck between diffusion effects and the Coriolis force. Under… … Wikipedia
Ekman-Transport — Der Ekman Transport ist die über eine turbulente Grenzschicht der Atmosphäre und des Ozeans auf der rotierenden Erde vertikal integrierte Strömung. Er ist benannt nach dem schwedischen Ozeanographen Vagn Walfrid Ekman, der die erste realistische… … Deutsch Wikipedia
Ekman number — The Ekman number, named for V. Walfrid Ekman, is a dimensionless number used in describing geophysical phenomena in the oceans and atmosphere. It characterises the ratio of viscous forces in a fluid to the fictitious forces arising from planetary … Wikipedia
Ekman layer — The layer of transition between the surface boundary layer, where shearing stress is constant, and the free atmosphere, where the atmosphere is treated as an ideal fluid in approximate geostrophic equilibrium. Also called a spiral layer … Aviation dictionary
Ekman spiral — The Ekman spiral refers to a structure of currents or winds near a horizontal boundary in which the flow direction rotates as one moves away from the boundary. It derives its name from the Swedish oceanographer Vagn Ekman. The deflection of… … Wikipedia
Divergent boundary — In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent… … Wikipedia
Convergent boundary — In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide. As … Wikipedia
