California is an area of diverse topography and has what many scientists call a Mediterranean climate. Various precipitation spatial and temporal patterns exist due to El Niño Southern Oscillation (ENSO) which can cause abnormal precipitation or droughts. As temperature increases due to the rise of CO2 in the atmosphere, it is rapidly changing the climate of not only California but the world. Using NOAA’s hourly precipitation data from rain gauges and modeled data, we performed an extensive analysis (Empirical Mode Decomposition) with SOI, PDO, and AMO to depict ENSO patterns. We found that indices have a stronger relationship with the gauge datasets than the modeled data. Also, SOI has a stronger correlation to the northern regions of California and PDO to the southern. Lastly, AMO shows insignificant correlations in California.
