Yellow Dust Storm from China Blankets South Korea

The spring is my least favorite time of the year in South Korea due to the yellow dust storms. These storms are a great reason to wear a mask:

Almost all of South Korea was shrouded Wednesday by a yellow dust storm originating in the Gobi Desert in northern China and Mongolia, the state weather agency said.

The yellow storm had spread to almost all of the country as of 7 a.m. and will affect the entire nation until Thursday, according to the Korea Meteorological Administration (KMA).

A fine dust advisory was issued for all parts of South Korea, authorities said.

The average hourly concentration of fine dust particles smaller than 10 micrometers in diameter, known as PM 10, had risen to 192 micrograms per cubic meter in Seoul as of 7 a.m. and 494 micrograms in the city of Ulsan, 307 kilometers southeast of Seoul, the KMA said.
