What is verga?

Verga refers to a meteorological phenomenon where precipitation falls from a cloud but evaporates before reaching the ground. This typically occurs in dry climates where the air beneath the cloud is unsaturated. As the precipitation falls, it encounters the dry air and evaporates, which can cause cooling and sometimes lead to downdrafts or microbursts. Virga can often be seen as streaks or shafts extending from a cloud, which appears to vanish before hitting the ground. It is most commonly associated with light rain or snow but can occur with any form of precipitation. This phenomenon is not only interesting to meteorologists but also can be visually striking when observed, often seen beneath altostratus, altocumulus, or cumulonimbus clouds.
