What is the meaning of "DS" in METAR?

Dust Storm
Drizzle
Low drifting
Ended

The correct answer is: Dust Storm

The correct interpretation of "DS" in a METAR report is "Dust Storm." METAR is an aviation routine weather report that provides essential information about current weather conditions at an airport. Within this context, certain abbreviations signify specific weather phenomena. "Dust Storm" indicates the presence of dust causing significant visibility reductions. This is particularly important for pilots as it can affect flight operations and necessitates adjustments to landing approaches and takeoffs due to impaired visibility. Other choices like drizzle and low drifting describe different weather conditions but do not correspond to the "DS" abbreviation. "Ended" is also not relevant in this context, as it does not specifically describe a weather condition but rather a state of termination. Each abbreviation in METAR aids pilots in quickly assessing weather conditions, and knowing the precise meanings is crucial for safe aviation practices.
