This paper studies the increased risk of flooding in three locations on the Alicante coast as a result of urban occupation of areas subject to this hazard. Given the various effects of flooding in areas of similar exposure, differences in vulnerability across regions at risk need to be analysed also in terms of the socioeconomic factors of the groups of society that may be affected, and of their perception of risk. With increased exposure to these phenomena comes also increased vulnerability. Increased risk of flooding on the coast of Alicante (Region of Valencia, Spainĭirectory of Open Access Journals (Sweden)įull Text Available In the past two decades, episodes of flooding on the coast of Alicante ( Spain have led to substantial losses in human life in economic terms. Por lo general, la cobertura nubosa total debe ser inferior a 4/8 para que se genere un diferencial termico y de presion entre el aire sobre las Las brisas marinas soplan bajo tipos de tiempo anticiclonicos, debiles gradientes de presion atmosferica, radiacion solar intensa y cielos practicamente despejados. Sea breezes trigger the formation of thunderstorm clouds (Cumulonimbus) at the sea breeze convergence zone, which also have a secondary impact on high-level (Cirrus, Cirrocumulus, Cirrostratus), medium-level (Altostratus, Altocumulus) and low-level clouds (Stratus, Stratocumulus, Nimbostratus) associated with the Cumulonimbus clouds (e.g., Cumulonimbus anvil). The results confirm the hypothesis that the effect of sea breezes on cloud genera is to increase the frequency of low (Stratus) and convective (Cumulus) clouds. This climatological study is mainly based on surface cloud observations at the Alicante-Ciudad Jardin station (central coastal plain) and on an extensive cloud observation field campaign at the Villena-Ciudad station (Prebetic mountain ranges) over a 3-yr study period (2003-2005). The study area is located in the southeast of the Iberian Peninsula (province of Alicante, Spain) and the survey corresponds to a 6-yr study period (2000-2005). Accordingly, the aim of this study is to statistically analyze the impact of sea breezes on cloud types in the convective internal boundary layer and in the sea breeze convergence zone. However, many numerical and observational studies have analyzed the ability of sea breezes to generate clouds in the convective internal boundary layer and in the sea breeze convergence zone. Generally, total cloud cover must be less than 4/8 in order to cause a thermal and pressure difference between land and sea air which allows the development of this local wind circulation. Sea breezes blow under anticyclonic weather types, weak surface pressure gradients, intense solar radiation and relatively cloud-free skies.
