The following file is a tarred and gzipped file containing a selection of FORTRAN code implementing Richardson's baroclinic model of the atmosphere. The code was written by Peter Lynch. Initial data based on observations for 0700Z, 20 May, 1910 are also included. You are welcome to experiment with the data and code. The code has been carefully checked out and is believed to be free of serious bugs. However, I cannot guarantee its integrity, and can offer only minimal assistance if problems arise.
