Fluoride removal by traditional precipitation generates huge amounts of a water-rich sludge with low quality, which has no commercial or industrial value.
The huge diversity and complexity of precipitation, including its forms, extent, intermittency, intensity, and temporal and spatial distribution, do not allow easy descriptions.
Quantification of groundwater recharge from precipitation in the huge sand dunes is an issue in accounting for regional water balance in the Badain Jaran Desert (BJD) where about 100 lakes exist between dunes.
"The beginning of debris flow is high precipitation, or long periods of precipitation," Dr. Reynard said.
If nothing is done to reduce carbon emissions over the next couple of decades, our climate models predict that there will be massive changes in the global precipitation and temperature patterns, with huge effects on water and food security, and dramatic sea-level rise.
But despite all the caveats, the precipitation from the cloud will be huge.
Because the world's biggest island has just 55,000 people and no industry, the condition of its huge ice sheet — as well as its temperature, precipitation and winds — is influenced by the global atmospheric and ocean currents that converge here.
As Figures 7 and 9 indicate, there is little difference between inter-scenario variability for both precipitation and temperature scenarios at any periods, compared with the huge differences across GCM models.
Nonetheless, the new stratigraphic framework indicates also that silica precipitation in the Cerratina cherty Limestone corresponds to a phase of huge volcanic activity in association with the Corsica-Sardinia block rotation at ~ 22 to 15 Ma (Fig. 7).
Even if the precipitation in the West does not decrease, higher temperatures by themselves create huge complications.
