Cold Front In Warm Advection - Typical Appearance In Vertical Cross Sections

by ZAMG and FMI


The vertical structure of CF in WA shows most clearly, that the front is indeed a Cold Front, despite being within warm advection.

Comparison of cross sections between a Cold Front and a Cold Front in Warm Advection (see Cold Front - Typical Appearance In Vertical Cross Sections ):

Locations of the cross section for both cases:

Cold Front in Warm Advection: 03 October 2006/12.00 UTC - Meteosat 8 10.8 image; position of vertical cross section indicated
Cold Front: 19 September 2005/12.00 UTC - Meteosat 8 10.8 image; position of vertical cross section indicated
Temperature advection:
03 October 2006/12.00 UTC - Vertical cross section; black: isentropes, red thick: warm advection, red thin: cold advection
19 September 2005/12.00 UTC - Vertical cross section; black: isentropes, red: warm advection (no cold advection present)
Vertical motion:
03 October 2006/12.00 UTC - Vertical cross section; black: isentropes, cyan thick: upward motion, cyan thin: downward motion
19 September 2005/12.00 UTC - Vertical cross section; black: isentropes, cyan thick: upward motion, cyan thin: downward motion
Vorticity advection:
03 October 2006/12.00 UTC - Vertical cross section; black: isentropes, green: PVA
19 September 2005/12.00 UTC - Vertical cross section; black: isentropes, green thick: PVA, green thin: NVA
Divergence:
03 October 2006/12.00 UTC - Vertical cross section; black: isentropes, magenta thick: convergence, magenta thin: divergence
19 September 2005/12.00 UTC - Vertical cross section; black: isentropes, magenta thick: convergence, magenta thin: divergence
Relative humidity:
03 October 2006/12.00 UTC - Vertical cross section; black: isentropes, blue solid: relative humidity > 60%, blue dashed: relative humidity < 70%
19 September 2005/12.00 UTC - Vertical cross section; black: isentropes, blue solid: relative humidity > 60%, blue dashed: relative humidity < 70%
