Winds of this type are usually called geostrophic winds.

Output would also be less dependent on location than it is on the ground, simply because terrain doesn't matter much when you're at 35,000ft; however, since the jetstream and other "geostrophic" winds don't blow much at latitudes near the equator, it would be useful primarily for middle - and higher-latitudes.

In the St. Lawrence Island polynya region, changes in regional oceanography due to the position or size of the Gulf of Anadyr gyre are ultimately related to the northward transport of water through the Bering Strait, and to the geostrophic balance within the Arctic Ocean basin.
-
In this simple model, the overflow is assumed to pass through a channel, sufficiently narrow to allow neglect of geostrophic effects.
-
Surface winds on a weather map do not blow exactly parallel to the isobars as in geostrophic and gradient winds.

Relation between the geostrophic flux of the Kuroshio in the Eastern China Sea and its large meander in the south of Japan.

Gradient winds are slightly more complex than geostrophic winds because they include the action of yet another physical force.

Finally, Buys Ballot's Law states that when you stand with your back to a geostrophic wind in the Northern Hemisphere, the center of low pressure will be to your left and the high pressure to your right.

The horizontal divergence of the balanced solution becomes important and the traditional balance equation of quasi-geostrophic dynamics must be extended.
