What does the weather code DS mean?

Explanation:
Dust Storm is indicated by that weather code because in standard weather observation codes each phenomena has its own two-letter tag, and DS is the tag reserved for a dust storm. A dust storm is a specific event where strong winds lift a large amount of dust into the atmosphere, greatly reducing visibility and creating hazardous travel and aviation conditions. This is more severe and distinct than simply “dust” (which would be a lighter, everyday dust presence) or “drizzle” (which has its own code for light rain). A funnel cloud refers to a rotating cloud that can lead to a tornado and is coded differently. So the code DS precisely identifies the hazardous dust-storm condition.
