In the last half century, the number of days with reports of Asian dust has increased five-fold. According to an analysis on data from Korea Meteorological Administration (KMA), the average number of days with Asian dust in a given year was about two in the 1960s. However, this number has increased to 11 in 2000s. In 1960s and 1970s, each decade had 3 years that were Asian-dust free. However, starting from 2000s, there has not been a single year without Asian dust. In just four months of 2018, Gyeonggi Province of South Korea issued 42 dust warnings and advisories, which has increased from 36 in the same period in 2017. This reflects the increase in average dust concentration level from 132.88 ppm (parts per million) in 2017 to 149 ppm in 2018. The situation is worsening since the dust particles are staying in the air longer. The average duration has increased from 16.3 hours to 19.8 hours in the last two years.
