What have you tried?

Do you want to create empty files based on your pattern?

No I want to copy contents of $file to new file to be created.

How about an awk program?

awk -F'[- ]' ' BEGIN {
        mon = "Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec"
        split ( mon, M );
} {
        sub (/[ \t]+$/, X)
        for ( i = 1; i <= 12; i++ )
        {
                if ( $2 == M || $2 == i )
                {
                        n = M "_" $NF
                        if ( n in FA )
                        {
                                F = M "_" $NF "_" C ".txt"
                        }
                        else
                        {
                                C += 1
                                F = M "_" $NF "_" C ".txt"
                                n = M "_" $NF
                                FA[n] = n
                        }
                        print $0 >> F
                }
        }
        close (F)
} ' file*

Use nawk instead in SunOS or Solaris
