FIGUEIRA, C., MENEZES DE SEQUEIRA, M., VASCONCELOS, R., PRADA, S. (2013) – Cloud water interception in the temperate laurel forest of Madeira Island. Hydrological Sciences Journal 58(1): 152-161. DOI:10.1080/02626667.2012.742952.​


​A cloud belt frequently forms on the windward side ofMadeira Island, between 800 and 1600 m a.s.l., as a result of adiabatic cooling of the northeastern trade winds that are forced upward. Temperate laurel forest is the most common vegetation inside that cloud belt altitudinal range. Cloud water interception was estimated by comparing precipitation and throughfall during a hydrological year. It totalled 200 mm (8% of rainfall) during 65 days (3 mm d-1) and seems to constitute a larger fraction of water input during drier months. Multiple linear regression between gauge standard deviation and throughfall throughout rain events shows that cloud interception is common before the onset of rainfall. Its role in the ecohydrology of laurel forest and in the island’s hydrology should be acknowledged. Further studies on this issue should be a priority in order to better understand these dynamics and provide tools for the correct management of this protected forest and the island’s groundwater resources.
