What describes the effect of virga?

Virga refers specifically to precipitation that falls from a cloud but evaporates before it can reach the ground. This phenomenon occurs when the atmospheric conditions below the cloud are dry enough that the falling water droplets or ice particles turn into vapor before making contact with the Earth's surface. As this precipitation evaporates, it can create a visual effect of streaks appearing to hang from the cloud, often seen as wispy extensions. Understanding virga is important for pilots and meteorologists as it can indicate changes in humidity and can affect visibility, making awareness of such weather phenomena essential for safe navigation and forecasting.
