gsw_Nsquared_lowerlimit

specified profile of minimum buoyancy frequency squared

Contents

USAGE:

Nsquared_lowerlimit = gsw_Nsquared_lowerlimit(p,long,lat)

DESCRIPTION:

Calculates the minimum Nsquared such that a cast is stable.

INPUT:

p     =  sea pressure                                           [ dbar ]
         ( i.e. absolute pressure - 10.1325 dbar )
long  =  longitude in decimal degrees                     [ 0 ... +360 ]
lat   =  latitude in decimal degrees north               [ -90 ... +90 ]
lat & long may have dimensions 1x1 or Mx1 or 1xN or MxN, where p is MxN.

OUTPUT:

Nsquared_lowerlimit  = Minimum Brunt-Vaisala Frequency squared   [ s-2 ]

EXAMPLE:

p   = [     10;      50;     125;     250;     600;    1000;]
long = 180;
lat = 4;
N2_lowerlimit = gsw_Nsquared_lowerlimit(p,long,lat)
N2_lowerlimit =
