Storm advancement coefficient determination according to origin and hazard rainfall in the Cuban archipelago

Abstract

In this paper, a generalization methodology of Martínez, Planos and Perdigón (2020) is presented. The storm advancement coefficient and its relationship with the specific type of storm precipitation hyetograph is determined. The storm advancement coefficient is a hydrological parameter used to determine the instant where the maximum rainfall intensity occurs for specific storms. This issue the selection of the rainfall temporal distribution model, which is very useful for hydraulic engineering design and hydrological prediction. The proposed approach, define the coefficient according to rainfall origin and its hazard; mainly for the meteorological events typical of the tropic interaction-middle latitudes, non-cyclonic tropical, and cyclonic. Finally, rainfall hyetographs for different hydrometeorological systems were obtained, as well as several types of hazards, which gives it a climatic and regional character. This paper is for the entire Cuban territory.
