Presentation on theme: " A type of weather modification Treatment used to increase precipitation – to provide water on dams and agricultural fields during drought seasons."— Presentation transcript:
Requires large amount of funds Doesn’t produce enough rain Rain do not fall on the right location Some believe that it does not work successfully at all… In other words… A large amount of money is wasted There is no established quantitative way of pursuing cloud seeding.

The ranges in which cloud seeding operations are likely to be successful Time Observed8-10 A.M. / 3 -5 P.M. Cloud Cover50-75% (4 – 6 Oktas) Wind Speed (and Direction)2 – 19 km/h (1-10 Knots) / (Direction varies based on the location) Humidity60% + Barometric Pressure980-1010 mb It is possible to establish a more accurate and precise way of predicting the ideality of Day for cloud seeding.
Wide range of cloud seeding data wherein taking into consideration other factors besides from the given factors Usage of Backpropagation Neural Network
