Mapping rainfall over the complex topography of Hawai‘i is not easy. It’s difficult to produce a good quality map that captures the extreme gradients and spatial variability of rainfall in …
Contributed by Katrina M. Fandrich (kfandrich@albany.edu) This study presents results from an ensemble of regional climate model simulations (periods 1996–2005 and 2026–2035) that are used to examine the effects of …

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…
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…
The Natural Area Reserve at the summit of Mt. Kaʻala on the island of Oʻahu serves as a refugia for native biodiversity and is of special ecohydrological significance as the forest captures water directly from passing clouds…
