“…However, this conclusion was based on the study of a small part of the northern SCS and whether this relation is applicable to the whole SCS region is questionable. Shi et al [2015c] attempted to improve the existing climatology of the evaporation duct in the SCS using a state-of-the-art evaporation duct model and an improved meteorology data set.

The interannual variability of the evaporation duct over the South China Sea is investigated during the boreal winter and summer seasons using data sets from the National Centers for Environment Prediction Climate Forecast System Reanalysis. During winter, the distribution is characterized by a tripole‐like structure, whereas in summer the pattern exhibits a west‐east contrast. Special attention is paid to the links of the evaporation duct with the regional evaporation by analyzing the leading empirical orthogonal functions of both elements. Both the structural similarity in spatial patterns and the significant correlation in the principal components imply the inherent relevance between evaporation duct and evaporation. During both the winter and summer seasons, the empirical orthogonal function principal component 1 of the evaporation duct and evaporation are linked significantly with the regional atmospheric dynamics, the primary factor dominating the whole South China Sea. The partial correlation analysis reveals that, similar to the evaporation process, surface wind is a more important factor affecting evaporation duct than sea surface temperature. The results also indicate that the influence of surface wind and SST not only has an obvious seasonal dependence, but also displays a prominent south‐north contrast.

“…Hence, this data set is suitable for longterm high-resolution analyses of EDH. Recently, McKeon (2013) and Shi et al (2015) applied the NCEP CFSR data set in the climatological analysis of the evaporation duct in the South China Sea. The results showed great potential for the NCEP CFSR data set to be utilised for in-depth studies of the relationships between EDH distribution and climate variations.…”

“…It has been found that the NPS model is the optimal model for calculating the EDH and estimating the modified refractivity profile. Recently, Shi et al used the NPS model and National Centers for Environmental Prediction Climate Forecast System Reanalysis (NCEP CFSR) climate reanalysis product to study the spatiotemporal characteristics of EDH in South China Sea (Shi et al, 2015). However, this work mainly focused on the statistical features of the EDH distribution and no detailed analysis of the regional climate variations and its effects on the EDH distribution was given.…”

An evaporation duct climatology is constructed for the Gulf of Aden using a 31-year high-resolution data set from the climate reanalysis product National Centers for Environmental Prediction Climate Forecast System Reanalysis. The climatology reveals spatio-temporal heterogeneity in the evaporation duct height (EDH) regulated by the strong interplay between the seasonal monsoon reversals and the related atmospheric and oceanic responses. It also reveals that the Gulf of Aden exhibits a special EDH distribution that is distinct from the adjacent Arabian Sea when the southwest monsoon dominates the gulf. Under these conditions, the EDH of the entire gulf is significantly higher than that of the adjoining Arabian Sea. A cliff-style EDH drop (referred to as the EDH cliff) forms at the mouth of the Gulf of Aden. Furthermore, the influence of the EDH cliff on marine radar was investigated using a ray-optics method. Based on the analysis, it was found that the local EDH significantly affects the radar detection ability beneath the evaporation duct for ships sailing in the Gulf of Aden.
