absolute vorticityの例文
- The potential vorticity is absolute vorticity divided by the vertical spacing between levels of constant entropy ( or potential temperature ).
- K m kg s | group = " nb " } } Given that the absolute vorticity is positive in the Northern Hemisphere and negative in the Southern Hemisphere, the threshold value should be taken as positive north of the Equator and negative south of it.
- The absolute vorticity of an air mass will change if the air mass is stretched ( or compressed ) in the " z " direction, but the potential vorticity is tracer of air masses over the timescale of a few days, particularly when viewed on levels of constant entropy.
- It is formed with the aid of potential vorticity, which is defined as the product of the isentropic density, i . e . the density that arises from using potential temperature as the vertical coordinate, and the absolute vorticity, given that this quantity attains quite different values for the troposphere and the stratosphere.
- Physically, the omega equation combines the effects of vertical differential of geostrophic absolute vorticity advection ( first term on the right-hand side ) and three-dimensional Laplacian of thickness thermal advection ( second term on the right-hand side ) and determines the resulting vertical motion ( as expressed by the dependent variable \ omega .)
