Impact of vertical stratification on the 2020 spring bloom in the Yellow Sea.

The Yellow Sea is one of the world's most abundant marine resources, providing food and economic benefits to the Korean and Chinese populations. In spring 2020, a decrease in the intensity of phytoplankton bloom was observed. While one study attributed this decline to a decrease in nutrient associated with the COVID-19 pandemic, our previous research proposed weakened thermal stratification accompanied by a surface cooling anomaly as the cause.

Causes for an extreme cold condition over Northeast Asia during April 2020.

Although 2020 was the fourth warmest year on record in northern Asia, the cold condition in April 2020 caused severe damage to the agricultural and marine ecosystems in northeastern Asia. Previous studies have indicated that the dipole atmospheric circulation over Siberia and the East Sea (Japan Sea) produced this cold environment with strong northwesterly wind. However, the potential causes of the dipole circulation over northeastern Asia remain unclear.

Decreasing patterns of depression in living alone across middle-aged and older men and women using a longitudinal mixed-effects model.

There is little evidence regarding the association between living arrangement and depression, and no studies have examined the age- and gender-specific differences in this association. The present study sought to examine the longitudinal changes in depression patterns between isolative living versus living in company among middle-aged and older men and women by obtaining data from waves 1-7 of the Korean Longitudinal Study of Aging (KloSA), which comprises a sample of persons at least 45 years of age in the Republic of Korea (2273 middle-aged and 1387 older men, 2805 middle aged and 1862 older women). Depression scores were based on the self-reported Center for Epidemiologic Studies Depression Scale (CES-D-10) short forms.

Combined effects of handgrip strength and sensory impairment on the prevalence of cognitive impairment among older adults in Korea.

Climate change over the Mediterranean and current destruction of marine ecosystem.

The Mediterranean is one of the most vulnerable regions to climate change and its summer climate is known to be affected by the South Asian summer monsoon (SASM) through the monsoon-desert teleconnection. In future, rainfall is expected to increase not only over the SASM area but also over the East Asian summer monsoon (EASM) and equatorial Atlantic regions. Here we show that the remote forcing regions affect the Mediterranean climate in the future.
