ESCI 445 Numerical Modeling of the Atmosphere and Oceans Barotropic Model Programming Exercise Write a program to numerically solve the Q G barotropic vorticity equation egg J1 g vg0 a where 3 I V3 3x 4 VZII The following table has the specifications for the model 6 to Writing output Write all output to one file Write output at time 0 and every 6 hours thereafter The output format should be 51 records each record containing 101 values In order to write the output every 3 hours you will find the MOD function of either or lDL handy Relaxation Use over relaxation as discussed in class When doing relaxation use previous time step s streamfunction as the first guess Note Updated values of vorticity are only calculated on the interior grid points leaving both the boundary points and points adjacent to the boundary unchanged For bonus points make a version of your model with cyclic east and west boundaries and run it as above only use quotbarotropicistreamfunctionicycliciinputdat as the input file illlsrinrlmims nuly 1m nyrl in In untannn g g mints um mljmm m 2 bnlnulzuy mu r us 1 in In numdnn
