1. The Use of Neural Network in Determining the Ideality of Day for Cloud SeedingbyCuesta, Yvanne Christine R.Uy, Ma. Ro-anne R.

2. CLOUD SEEDING • A type of weather modification • Treatment used to increase precipitation – to provide water on dams and agricultural fields during drought seasons

3. CLOUD SEEDING OPERATION

4. ISSUES • 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.

5. Neural Network • information processing model inspired by the human brain • used in classification through pattern based learning

6. Process Flowchart Acquisition and Compilation of Cloud Seeding Data • Acquisition and Programming of Implementing Software Conversion of data into data input Training of program Testing and Validation of Program

16. Conclusion • The ranges in which cloud seeding operations are likely to be successful • It is possible to establish a more accurate and precise way of predicting the ideality of Day for cloud seeding.

17. Recommendations • Wide range of cloud seeding data wherein taking into consideration other factors besides from the given factors • Usage of BackpropagationNeural Network
