_D_e_s_c_r_i_p_t_i_o_n:

     Produce storm statistics/analysis. This function was used to
     produce the figures in the paper Benestad, Sorteberg and Chen,
     'The use of a Calculus-based Cyclone Identification method for
     generating storm statistics' submitted to Climate Dynamics 2004.

_A_r_g_u_m_e_n_t_s:

   fname: Filename of cyclone stats data.

    psl0: Treshold value

    topo: Name of topography file.

 cyclone: Treshold: TRUE -> less than, FALSE -> greater than

   x.rng: Interval of longitudes of interest (deg E)

   y.rng: Interval of latitudes of interest (deg N)

     cmp: Flag set for comparing two storm data sets: one given a fname
          and the default in cyclones ('data(storms)')

     mon: Months to plot a histogram for.
