What is the definition of Virga?

Virga refers specifically to precipitation, such as rain or snow, that falls from a cloud but evaporates before it reaches the ground. This phenomenon typically occurs in dry or low-humidity environments where the air is unable to support the moisture, causing it to vanish as it descends. It can often be seen in the sky as streaks of rain or snow that do not touch the surface, making it an interesting meteorological occurrence. Understanding virga is important for meteorologists as it helps them predict weather patterns and understand precipitation processes.
