Abstract
In this study, we developed a Nakdong- marine environmental information system (N-MEIS) using automatic
weather station (AWS) data to elucidate the characteristics of wind distribution and land/sea breezes in the
Doyo-deung barrier islands located in the brackish water zone off the coast of the Nakdong River Estuary
(NRE), Busan, South Korea. From May 2015 to the present day, the N-MEIS was run in real-time with
sampling intervals of 10 second using long-term evolution communication, an operation rate of approximately
98% in AWS, and periodic marine observations recorded 1–4 times per year. From April 2016 to October 2019,
the average annual wind speed in the Doyo-deung barrier islands was 3.8 m/s (range, 2.11–5.1 m/s) and the
maximum wind speed, recorded in February 2019, was 46.8 m/s. These values are usually influenced by lowpressure
blasts or instantaneous wind speed. However, the maximum monthly mean velocity is also influenced
by typhoons occurring in early autumn from August to September. Based on the percentages of wind directions
recorded, the prevailing winds blow in ESE’ly and SSW’ly directions. The distribution of wind directions in
summer was similar to that in spring, and the distribution in autumn tended to be similar to that in winter. The
mean wind velocities at Yeongdo and Gadeokdo islands approximately 9–12 km west, were two times higher
than those at Haeundae beach approximately over 20 km east of the study area. Research on the dynamic wind
distribution is necessary to manage erosion and sedimentation around the barrier islands, beach pollution from
floating materials transported overland, coastal sand dune activity, changes in migratory bird habitats, and
impacts on ecosystem health more effectively. The evolution and developments of the N-MEIS facilitates this
process understand. Further studies should integrate real-time/periodic marine observations and predictions with
environmental sensitivity index (ESI) maps.
