factors effecting fog Harvesting
Answers
Answer:
The following factors affect the volume of water that can be extracted from fogs and the frequency with which the water can be harvested: Frequency of fog occurrence, which is a function of atmospheric pressure and circulation, oceanic water temperature, and the presence of thermal inversions.
Technology requires very specific climatologic and topographic conditions. Yield is difficult to predict so a thorough pilot project is required in every case
Yield is very sensitive to changes in climate conditions and so a back-up supply is required
Fog collection is unlikely to be of regional or national importance as a water supply. Emphasis is on the local level which requires full community participation
If the collectors are not close to the point of use then the cost of the pipeline can make the system uneconomic and hydraulically difficult
