VA is the code for which phenomenon?

Explanation:
Volcanic ash is what VA stands for. In aviation weather shorthand, this two-letter code flags a volcanic ash cloud, a major hazard because ash can damage engines, abrade surfaces, and severely reduce visibility. The other phenomena have their own distinct codes—snow, rain, and dust/sand use different abbreviations—so VA is specifically reserved for volcanic ash.
