convective instability उदाहरण वाक्य

Internal rotation in stars ( Ogilvie, 2007 ), and even planetary dynamos ( Petitdemange et al ., 2008 ) may, under some circumstances, be vulnerable to the MRI in combination with convective instabilities.
If you enjoy analyzing things numerically, you can look at the empirical laws we use to model convective instability-like a Rayleigh-Taylor instability model . talk ) 14 : 46, 28 July 2012 ( UTC)
Convective instability is also termed " static instability ", because the instability does not depend on the existing motion of the air; this contrasts with dynamic instability where instability is dependent on the motion of air and its associated effects such as dynamic lifting.
Or, the wind gusts may be produced by a dry cold front, that is, a cold front that is moving into a dry air mass and is producing no convective instability resulting from cooler air riding over heated ground can maintain the dust storm initiated at the front.
By considering modes with zero group velocity and determining whether they grow or decay, we can determine whether an initial condition which is localised around x = 0 moves away from x = 0 as it grows, with y ( 0, t ) \ rightarrow 0 ( convective instability ); or whether y ( 0, t ) \ rightarrow \ infty ( absolute instability ).

B . A . Finlayson first explained in 1970 ( in his paper " Convective instability of ferromagnetic fluids ", " Journal of Fluid Mechanics ", "'40 "': 753-767 ) how an external magnetic field imposed on a ferrofluid with varying magnetic susceptibility, e . g ., due to a temperature gradient, results in a nonuniform magnetic body force, which leads to "'thermomagnetic convection " '.
