"Yellow Dust" is a seasonal meteorological phenomenon affecting most of East Asia from the months of March to May.
The dust storms originate from the deserts of Inner Mongolia and northern China with strong winds kicking up dense clouds of dry soil particles which are airborne and carried across the country to Korea and Japan.
This past Saturday, Korea experienced its worst dust storm since it started recording data in 2003 and weather experts say there will be more yellow dust storms affecting the country over the next few months.
In the last decade, it has become a serious problem due to the increase of industrial pollutants contained in the dust.
And authorities advise some precautions to minimize the impact of the dust.
Firstly, stay indoors if possible and while you are inside keep the windows and doors shut and turn on an air ventilation system.
When you do go outside make sure to wear a mask to protect yourself from the dust particles.
And if you are driving during a dust storm keep the windows and air vents closed and switch the air conditioner to recirculate.
Experts say China's rapid industrialization and intensified desertification are causing the dust storms to be longer and more frequent.

The sandstorm is directly connected to the dust from the dry river beds which is blowing into Beijing. I think that there are two reasons behind this: one is climate change and the other is the over-exploitation of China's rivers and water resources."
Meanwhile, Chinese Premier Wen Jiabao visited the nation's drought-plagued southwestern Yunnan Province on Sunday calling for more efforts to relieve over 50 million people suffering from less rainfall and unusually high temperatures.

Experts predict that Korea will be hit by especially strong dust storms this year but it will luckily be quite minimal compared to what is going on in southern China which is suffering from its worst drought in a century.
