Research Title: Quantifying the Spatio-Temporal Variability of Storm Arrival Rates for The Continental United States.

Research Synopsis: It is known that earth’s climate exhibits decadal to multi-decadal variability, i.e., cyclic pattern of warming and cooling, which influence the temporal and spatial changes in the frequency, and magnitude of events. Based on this, this project aims to determine the trends in precipitation storms arrival rates (SAR), Extreme storm arrival rate (ESAR) and prolonged event arrival rate (EAR) for the continental United States. These arrival rates are analyzed to understand their spatial and temporal manifestations. The data used for the analysis is historic precipitation data obtained from Global Historical Climatology Network (GHCN), a network of 1244 ground stations that have 115 years (1900 to 2015) of temporal coverage. To study these aspects the research incorporates a combination of statistical approaches including imputation of missing values and estimation of the storm arrival rates. Robust Principal Component Analysis (rPCA) is used to detect the space-time variability of SAR and ESAR across the country.
