When speaking about reducing the precipitation area of the BPP ash field, first of all taking disconnection and recultivation of the 2nd ash field is considered.
Quality improvement - upgrades to the precipitation area of the plant will enable Gramercy to produce 1) a smelter grade alumina with improved granulometry and attrition index, and 2) a chemical grade alumina with improved grinding and dissolving characteristics.
The intent of this generalization method is to improve upon traditional hydrographic presentation to produce a river map that does not under-represent rivers and streams in high precipitation areas or over-represent them in arid areas.
Arid areas of the conterminous United States appear with more negative space on the map than high precipitation areas.
The enhancements, which will benefit all aviation customers using WSI Pilotbrief(R), WSI InFlight(R) or WSI Fusion(TM) products, result in a more accurate and timely depiction of the location and movement of winter precipitation areas.
Miller, General Manager of WSI's Aviation Division, "but now we are using high resolution, near real-time data to provide a more complete picture of the atmosphere and to more accurately show the migration of the rain/snow/mixed precipitation areas as a storm progresses.

In the Working Views category, first place winner is Nitin Dhamane, Hatch, Canada, for "Mining for Future," showing bauxite grinding, crushing and precipitation areas of an alumina refinery.
Applying the conceptual framework of events and processes (Figure 1), the study first identifies precipitation areas from precipitation states (such as states in Figure 2), associates these precipitation areas (footprints) to form processes based on spatial and temporal proximity, and then assembles these processes in space and time to form events.
Consequently, the conceptual model of a precipitation process is a set of temporally related areas of precipitation, and each of the precipitation areas corresponds to a group of grid cells that show how precipitation varies in that area (Figure 3).
In addition, it will offer local, metro, state and regional "zoomable" radar animations that will show precipitation areas on the move.
