Upstream - toward the source of the flow, or located in the area from which the flow is coming ...
upstream - In the direction from which a fluid is flowing.
upwind - In the direction from which the wind is blowing.
UTC - See universal time.
Upstream Slope The part of the dam which is in contact with the reservoir water. On earthen dams, this slope must be protected from the erosive action of waves by rock riprap or concrete.
UPSTREAM / UPWIND- The direction from which a flow is coming from. A boat moving down a river will be moving downstream but came from upstream.
(Upstream and Downstream) : The junction of the face of a dam with the ground surface

The region upstream from a wind speed maximum in a jetstream (jet max), in which air is approaching (entering) the region of maximum winds, and therefore is accelerating.
About 40 km upstream of the mission the resident police constable organised a similar evacuation from the Police Station. Here the river rose about 25 metres above its normal level, destroying most of the buildings.
Toe of Dam (Upstream and Downstream): The junction of the face of a dam with the ground surface.
Tonitrophobia: The fear of thunder. See Astraphobia, Astrapophobia, Brontophobia, Ceraunophobia, and Keraunophobia.
ReachA section of river or stream between an upstream and downstream location, ...
(a) A low dam built across a stream to raise the upstream water level (fixed-crest weir when uncontrolled);
(b) A structure built across a stream or channel for the purpose of measuring flow (measuring or gaging weir).
Severe weather and excessive rainfall often occur near or just upstream from a theta-e ridge.THETAEAbbreviation for Theta-e; the temperature a parcel of air would have if
a) it was lifted until it became saturated,
b) all water vapor was ...
Gauge relation An empirical curve relating stream discharge or stage at a point on a stream to discharge or stage at one or more upstream points and, possibly, to other parameters. Also called stage relation.
Backwater EffectIn hydrologic terms, the effect which a dam or other obstruction has in raising the surface of the water upstream from it.
Downslope windstorms of great severity require an upstream mountain range having a crest at least roughly 1 km in height above terrain to its lee, and with a steep leeside slope.
Entrance Region - The region upstream from a wind speed maximum in a jet stream (jet max), in which air is approaching (entering) the region of maximum winds, and therefore is accelerating.
The flow can even reverse during the day, and the warm air flows upstream. This is seen, for example, in the valley of the Columbia River at Trail, B.C.
When forecasting temperatures, look at the temperatures upstream from the station for which you making a forecast. If they are warmer, that means warmer air is being transported towards your station and the temperature should rise.
Right Entrance Region (or Right Rear Quadrant) - The area upstream from and to the right of an upper-level jet max (as would be viewed looking along the direction of flow).
A weather forecaster who describes the upstream weather pattern as having positive vorticity is referring to the approach of a storm (low pressure center and associated front), ...
Theta-e Ridge - An axis of relatively high values of theta-e. Severe weather and excessive rainfall often occur near or just upstream from a theta-e ridge.
