Disturbance Driven Rainfall on O‘ahu

This research explores the relationship between 4-types of atmospheric disturbances and their contributions to daily rainfall on O‘ahu Hawai‘i. On average, atmospheric disturbances account for 29% of the annual and 41% of the seasonal (Nov – April) rainfall on O‘ahu Hawai‘i. Cold, fronts are the most common disturbance type, and fronts that cross over the island are shown to bring significantly more rainfall than the fronts that track to the north of the Island chain…

Using Statistics to Select Atmospheric Predictor Variables

An exploratory analysis found that atmospheric predictor variables selected through statistical methods can lead to more accurate rainfall projections when compared to the previous predictor set used in statistical downscaling for rainfall projections in Hawaiʻi. This figure shows the skill of a linear model in projecting rainfall…
