Abstract:  Atmosperic rivers (ARs) are elongated regions of water vapor in the atmosphere responsible for the heavy precipitation of the California winters. The impact of climate change on ARs raises concerns regarding the water supply of the state which is highly dependent on those extreme events. While the literature agrees that we will see fewer but heavier rainy days, the change on the total yearly precipitation is unclear. Our objective is to reach a better understanding of the relationship between ARs and precipitation in order to quantify the risk of drought in California in the future. We first develop two distributed approaches to spatial modeling to allow us to tackle the high resolution spatial dataset at hand. Then we outline the future work in spatial regression to reconcile the water vapor data and the precipitation data.
