<p><b>Nouvelle page</b></p><div>The "ok_hines" parameter is a logical flag, i.e. to be set to "y" (or equivalently ".true.") or "n" (or equivalently ".false.") in the run.def file.<br />
<br />
If on, this parametrization accounts for the effect of gravity waves in the stratosphere when the later is not represented in the GCM. This is essentially a depreciated scheme, superseded by the more recent non-orographic gravity wave parametrization (flag "ok_gwd_rando").<br />
<br />
In practice, when running in configurations without an explicit representation of the stratosphere (i.e. with 39 model levels or less) then one should have '''ok_hines=y''' and '''ok_gwd_rando=n''', whereas when running with the stratosphere (e.g. 79 model levels or more) then one should use '''ok_hines=n''' and '''ok_gwd_rando=y'''<br />
