224 and fifth scenarios. The first scenarios we modeled by using all of the global climate indices
index data. The third scenarios we choose the highest correlation each variable. The other scenarios are fourth and sixth scenarios using principal component analysis with Eigen value 75
and 95.

4. CONCLUSION
Classification of precipitation on dry season which divided into three classes can be implemented by using LVQ method. The accuracy of this classification is 71.05.For the future
work, we suggest to add the longer precipitation data and choose the best variety learning rate.
