Improving Rainfall Index Insurance: Evaluating Effects of Fine-Scale Data and Interactive Tools in the PRF-RI Program
… inception, the Pasture, Rangeland, and Forage Rainfall Index (PRF-RI) insurance program has issued a total of $8.8 billion in payouts. Given the program's significance, this thesis investigates methodologies to help improve it. For the first part, we evaluated the impact of finer-scale …

Teleconnections between seasonal rainfall in coastal Tanzania and Enso
The modulation of Tanzanian coastal rainfall variability with the El Nino/Southern oscillation (ENSO), the largest known mode of Southern Hemisphere climatic variation is examined. A rainfall index was formulated from variable Tanzanian coastal stations and used to identify the rainfall …

Composite structure of tropical cyclones in the SW Indian Ocean
… TC on the poleward side. Spectral analysis of a rainfall index compiled from Mauritius data demonstrates spectral peaks at the seasonal and intra-seasonal scale. Three peaks were identified. one within the 40-60 day Madden Julian Oscillation. one at 23 days and one with a 16 day oscillation. The …

Orographic Precipitation Over the Island of Oahu
… The HOP model vertical motion and Orographic Rainfall Index (ORI) are correlated with precipitation during the month of February 2015, but the microphysics of the HOP model is insufficient to produce a meaningful diagnosis of the actual precipitation during that time period. The ORI and …

Applications of Box-Jenkins methods of time series analysis to the reconstruction of drought from tree rings
… climatic variable, and the output is a tree-ring index. The estimated impulse response function weights the importance of past and current years' climate on the current year's ring. The identified transfer function model indicates how many past years' rings are necessary to account for the effects …

Assessing Crash Occurrence On Urban Freeways Using Static And Dynamic Factors By Applying A System Of Interrelated Equations
… the probability of crash occurrence, including a rainfall index that has been estimated using a logistic regression model. The study corridor is a 36.25 mile stretch of Interstate 4 in Central Florida. For the first two sections, crash cases from 1999 through 2002 were considered. Conventionally …

Lie Analysis for Partial Differential Equations in Finance
… are priced considering weather variables such as rainfall, temperature, humidity and wind as the underlying asset. Some recent researches suggest to model the amount of rainfall by considering the mean reverting processes. As an example, the Ornstein Uhlenbeck process was proposed by Allen [3] to …
