Professor Kyung-Ae Park's research lab specializes in ocean-atmosphere interactions, with a focus on sea surface temperature (SST) variability, oceanic frontal systems, and their impacts on atmospheric boundary layer dynamics and surface winds. The lab employs satellite remote sensing data—particularly from scatterometers and infrared sensors—to investigate how features such as Gulf Stream rings, the Subpolar Front in the East Sea, and long-term SST trends influence wind patterns, boundary layer stability, and air-sea heat exchange. Research also extends to climate change detection, analyzing long-term SST trends and extreme temperature events in the East Sea (Sea of Japan).
Figures are computed from collected data and may differ slightly.
Modifications to surface winds by currents and sea surface temperature (SST) gradients near frontal boundaries of Gulf Stream rings are analyzed using satellite SST and scatterometer (NASA's Quick Scatterometer (QuikSCAT), NASA scatterometer (NSCAT)) wind observations. A component of scatterometer wind approximately equal and opposite to the surface current vector is observed and attributed to the fact that scatterometers detect relative motion of water and air. Warm‐core ring (WCR) SSTs act to
The spatial pattern of sea surface temperature(SST) fronts and its seasonality are presented for the entire East(Japan) Sea. They are based on semi‐monthly sea surface temperature(SST) gradient maps constructed from declouded SST images over the period 1990–1995. Fronts in the East Sea can be assigned to the Subpolar Front (SPF) in its central sea areas and to other fronts along the continental shelves. It is observed for the first time that the SPF, located mostly along about 40°N between 132.3
Different strategies should be used to increase medication adherence in geriatric diabetic patients, depending on institutions whether they are treated.
Long-term trends of sea surface temperature (SST) of the East Sea (Sea of Japan, EJS) were estimated by using 37-year-long satellite data, for the observation period from 1982 to 2018. Overall, the SST tended to increase with time, for all analyzed regions. However, the warming trend was steeper in the earlier decades since the 1980s and slowed down during the recent two decades. Based on the analysis of the occurrence of events with extreme SST (high in the summertime and low in the wintertime)

Satellite‐borne scatterometer and infrared data collected over Gulf Stream warm and cold core rings are used to study the effect of the sea‐air temperature difference on the wind speed over rings. The observed acceleration of the wind over warm core rings and deceleration over cold core rings is found to be consistent with that predicted by the planetary boundary layer model of Brown and Foster [1994] . In addition it is shown that the distance over which the winds respond to an ocean surface te
During the last three decades, South Korea has experienced a remarkable economic growth that is often referred to as a miracle. The densely populated country, with little arable land, virtually no mineral reserves, and an excessively heavy military burden, has recorded one of the highest rates of economic growth of any country. From 1953 to 1990, South Korea's GNP registered an average annual growth rate of 8 percent, with many peaks over 10 percent. These rates surpassed the 4 to 5 percent of t
High-resolution sea surface temperature (SST) images are essential to study the highly variable small-scale oceanic phenomena in a coastal region. Most previous SST algorithms are focused on the low or medium resolution SST from the near polar orbiting or geostationary satellites. The Landsat 8 Operational Land Imager and Thermal Infrared Sensor (OLI/TIRS) makes it possible to obtain high-resolution SST images of coastal regions. This study performed a matchup procedure between 276 Landsat 8 ima
In this study, seven, global, blended, sea surface temperature (SST) analyses, including Operational SST and Sea Ice Analysis (OSTIA), Canadian Meteorological Centre (CMC) analysis, Optimum Interpolation SST (OISST), Remote Sensing System (REMSS) analysis, Multi-scale Ultra-high Resolution SST (MURSST), Merged Satellite and In situ Data Global Daily SST (MGDSST), and Geo-Polar Blended SST (Blended SST) were conducted. In-situ temperature measurements were used for the years 2014–2018, from 35 na
Unprecedented cold water was observed off the east coast of Korea in the summer of 2007, with the lowest temperature since 1961. The 9–year QuikSCAT satellite scatterometer wind field showed that the spectacular coastal upwelling was induced by Ekman transport to the offshore area by strong southerly winds. These characteristic winds were produced by the large scale air pressure distribution of typhoon Pabuk to the west, which stayed longest for the past half century, along with the North Pacifi
