The purpose of this research was to compare the variability of the Titicaca Lake water level to the Pacific Decadal Oscillation (PDO) between 1914 and 2014 and relate it was compared to El Niño - Southern Oscillation (ENSO) between 1969 and 2014 to evalute the hydrological cycle and perform rainfall forecast. The results show that the Lake Titicaca water level to decrease (increase) in the positive (negative) phase of the PDO. Likewise, the negative phase (positive) of ENSO generates patterns of positive anomalies (negative) of precipitation. Therefore, the positive (negative) phase of PDO, with greater probability of positive phase ENSO events (negative), precipitation anomalies shows negative (positive) which can be associated with the decrease (increase) in Titicaca Lake water level.
Your results would greatly benefit from more rigorous statistical tests regarding the interdecadal and interannual variability of Lake Titicaca with respect to ENSO and PDO phases. Among those tests and metrics are conditional probabilistic analysis, contingency tables, and Kolmogorov-Smirnov test of difference between probability distribution functions.
Thank you very much for your contribution to the Conference.
