Quasi steady state

From Glossary of Meteorology



quasi steady state

A situation that is changing slowly enough that it can be considered to be constant.

For example, atmospheric turbulence has a fast response time, while the atmospheric boundary layer depth that controls the turbulence grows with a slower timescale. Thus, turbulence can be analyzed as if it were unchanging because it quickly reaches equilibrium for any instantaneous boundary layer depth.

estado cuasi estacionario

Es una situación que está cambiando lo suficientemente lentamente como para que pueda considerarse constante.

Por ejemplo, la turbulencia atmosférica tiene un tiempo de respuesta rápido, mientras que la profundidad de la capa límite atmosférica que controla la turbulencia crece con una escala de tiempo más lenta. Así, la turbulencia puede analizarse como si fuera invariable, ya que alcanza rápidamente el equilibrio para cualquier profundidad de capa límite instantánea.
