Short summary
Short summary
This study presents a probabilistic model able to reproduce the spatial patterns of rainfall on tropical islands with complex topography. It sheds new light on rainfall variability at the island scale, and explores the links between rainfall patterns and atmospheric circulation. The proposed model has been tested on two islands of the tropical Pacific, and demonstrates good skills in simulating both site-specific and island-scale rain behavior.

Editorial statement
Giant CCN have long been recognised as highly important in warm marine clouds, as while these are low in number, they often dictate precipitation rates and thus many climate-important properties such as cloud optical thickness and lifetime. However, measuring these particles is remains challenging on a technical level and many models of their production are poorly constrained. This paper presents the results using a new methodology and goes on to explore the role of coastlines in enhancing wave breaking and thus giant CCN production.

Short summary
Sea salt aerosol is an important marine aerosol that may be produced in greater quantities in coastal regions than over the open ocean. This study observed these particles along the windward coastline of O'ahu, Hawai'i, to understand how wind and waves influence their production and dispersal. Overall, wave heights were the strongest variable correlated with changes in aerosol concentrations, while wind speeds played an important role in their horizontal dispersal and vertical mixing.
