“…This data set has been widely used in the spatiotemporal analysis of evaporation duct and proven to be in good reliability to present the actual EDH [ Frederickson et al ., ; Shi et al ., ]. More details of the calculation of EDH please refer to our previous works [ Yang et al ., ; Shi et al ., ; Zhang et al ., ; Yang et al ., ]. A detailed flowchart of the model algorithm can also be found in [ Yang et al ., ].…”

“…To overcome these limitations, efforts have been made to estimate the evaporation duct from air‐sea variables (e.g., the air temperature, sea surface temperature (SST), surface winds, pressure, and humidity) through the approximate combination of bulk models and reanalysis products. This method has been used in global and regional evaporation duct climatological studies and has proved to be both effective and efficient [ Twigg , ; Frederickson et al ., ; Yang et al ., ; Zhang et al ., ]. Several studies based on this method have provided some of the basic characteristics of the spatiotemporal distribution of the evaporation duct in the SCS.…”

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.

Impact of Typhoon on Evaporation Duct in the Northwest Pacific Ocean

Evaporation duct is a layer above the ocean surface due to the inherent humidity inversion at the air-sea boundary layer. The formation of the duct depends on meteorological factors near the ocean surface and is affected by weather process above the ocean. The presence of this duct can have profound effects on over-water electromagnetic propagation at microwave bands. However, the information on evaporation duct features during the period of typhoon is limited. Here we show the impact of a typhoon on evaporation duct using the typhoon Parpiroon occurred in 2012 as an example. It is very interesting to find that there is an ''evaporation duct eye'' with very low evaporation duct height in the eye of typhoon. The trajectory of the typhoon center is almost consistent with that of the evaporation duct height minimum center during the typhoon Parpiroon. This is also confirmed by 19 more typhoons over northwest Pacific Ocean in 2018. Furthermore, we found that the low wind speed in the typhoon center is the primary cause of this interesting phenomenon. Our results demonstrate the characteristics of evaporation duct distribution during the typhoon process and illustrate the correlation between typhoon trajectory and evaporation duct height minimum center trajectory.
