    <p>Is it because f0 applies to the southern limit of the domain
      (f=f0+beta*(y-y0), where y0 is at j=1) and beta was chosen to be
      representative of the mid-latitude of the domain?</p>

      <p>Hi David,<br>
      </p>
      <p><br>
      </p>
      <p>Thanks for alerting this to us. These numbers came from Ed
        Doddridge's SO setup, and values probably overlooked as the
        tutorial lat-lon domain evolved to final form...<br>
      </p>
      <p>but not sure why they were originally chosen as such. Perhaps
        Ed can recall?<br>
