<span style="font-family: Courier New,courier,monaco,monospace,sans-serif;">gfdda_end_h</span>. What does it stand for? And if I want to do fdda nudging
for say 17 years (utilizing restarts between each year), what should I
set this to? I set it previously to 24 (hours), not knowing what it
does, should I set it to one whole year (since I restart my run each
year). <br><br>Also, I already tested the differences, and noticed the huge wind differences between setting it for 1 whole year (more than 8000 <span style="font-family: Courier New,courier,monaco,monospace,sans-serif;">end_h</span>), and 6 hours only. If my assumption is correct, then is there a maximum value for the <span style="font-family: Courier New,courier,monaco,monospace,sans-serif;">end_h</span>? If I want to to nudge for 17 years (with restarts every year), should I set to that high value of <span style="font-family: Courier New,courier,monaco,monospace,sans-serif;">end_h</span> straightaway? Or is it enough to set it to exceed one year (>8000 hours <span style="font-family: Courier New,courier,monaco,monospace,sans-serif;">end_h</span>), for every boundary file of the restarts (since the values of <span style="font-family: Courier New,courier,monaco,monospace,sans-serif;">end_h</span> are written in the boundary files, after <span
style="font-weight: bold;">./real.exe</span>)?<br></div></div></body></html>
