I so love how models not only waffle from 1 operational run to the next from hundreds of miles to thousand of miles. Id really like to know what changes so much from 1 model run to the next to make such huge changes instead of the next model run slowly trending to that next solution. Ie a costal that goes right to a lake cutter on the next run. I wish we would get more feedback from what changed. btw i used the costal to lake cutter just as an example from what has happenend before.
