   Whipping winds carried a massive cloud of dust across China and the
   Korean Peninsula on April 11, 2023. The true-color image acquired by
   the Moderate Resolution Imaging Spectroradiometer (MODIS) on board
   NASA’s Terra satellite on that same day shows dense dust mixing with
   cloud over eastern China, the Yellow Sea, and the Korean Peninsula. The
   dust is so thick that the land and water underneath are obscured from
   view over much of the area. Outlines that follow the coastlines have
   been added to the image—without these, it would be very difficult to
   tell where the land meets the water.

   Dust storms are common over China, especially in the spring, when
   strong winds sweep dust from the Gobi Desert. The Gobi Desert, located
   in Mongolia and northwestern China, is filled with copious amounts of
   dust and sand, which easily is lifted into the atmosphere by passing
   winds. Since March 10, China has experienced four severe dust
   storms—unusual in both severity and frequency even for springtime. It
   is also unusual for such a severe storm to reach the Korean Peninsula
   and Japan.

   Dust storms can create serious health issues, especially when
   particulate matter reaches high levels. On April 11, the Beijing
   Municipal Ecological and Environmental Monitoring Center reported that
   PM10 concentrations measured more than 1,321 micrograms per cubic
   meter—a level almost 30 times the daily guideline set by the World
   Health Organization. PM10 are particles that measure less than 10
   microns, allowing them to be inhaled and reach the lungs. On that same
   day, Air Korea reported “very unhealthy” air in more than a dozen
   locations in southern South Korea, especially Jeju Island (also known
   as Jeju-do), which sits off the southern tip of South Korea.
