[GEMPAK #CAS-776545]: CINS GEMPAK

Hi Daniel,

CINS is the term used in GEMPAK for Convective Inhibition, typically just 
called CIN.

From http://www.unidata.ucar.edu/cgi-bin/gempak/manual/apxA_index

CINS - Convective Inhibition
  
        CINS = GRAVTY * SUMN ( DELZ * ( TP - TE ) / TE )
               SUMN = sum over sounding layers from top of the mixed 
                      layer to LFCT for which ( TP - TE ) is less 
                      than zero.
               DELZ = incremental depth
               TP   = temperature of a parcel from the lowest 
                      !500 m of the atmosphere, raised dry 
                      adiabatically to the LCL and moist
                      adiabatically thereafter
               TE   = temperature of the environment

CINV - CINS computed by using virtual temperature
  
        CINV = GRAVTY * SUMN ( DELZ * ( TVP - TVE ) / TVE )
               SUMN = sum over sounding layers from top of the mixed 
                      layer to LFCV for which ( TVP - TVE ) is less 
                      than zero.
               DELZ = incremental depth
               TVP  = virtual temperature of a parcel from the
                      lowest !500 m of the atmosphere, raised
                      dry adiabatically to the LCL and moist
                      adiabatically thereafter
               TVE  = virtual temperature of the environment
