Explanations: answer key for all 10 questions

Q1: What is virga?
Answer: Precipitation that evaporates before reaching the ground
Rain or snow falls from a cloud but dries up in the air below.
Q2: What does the Latin word virga mean?
Answer: Twig or branch
The wispy streaks can look like twigs or a broom.
Q3: Where is virga especially common?
Answer: Deserts and dry regions
Dry air below the cloud quickly evaporates falling drops.
Q4: What happens to air when virga evaporates?
Answer: It cools and becomes heavier
Evaporation absorbs heat, so the air cools and can sink rapidly.
Q5: Why can virga be dangerous for aircraft?
Answer: It can trigger downbursts of sinking air
Cold air rushing down can create sudden wind shear near airports.
Q6: Which clouds often produce virga?
Answer: Altocumulus and altostratus
Mid-level clouds often release precipitation that never reaches the ground.
Q7: What is a dry thunderstorm?
Answer: A storm whose rain evaporates before reaching the ground
Lightning without rain at the surface can start wildfires.
Q8: What can falling ice virga create in a cloud deck?
Answer: A fallstreak hole
Ice crystals trigger freezing and fall out, leaving a round gap with streaks below.
Q9: What kind of virga occurs on Venus?
Answer: Sulfuric acid rain that evaporates
Acid droplets fall but evaporate in the hot lower atmosphere.
Q10: Which nickname is sometimes used for virga?
Answer: Phantom rain
The rain appears to fall but never arrives.

Virga Quiz – Rain That Never Lands

Virga is rain, snow or ice that falls from a cloud but evaporates or sublimates before reaching the ground. It appears as gray or white streaks hanging below the cloud, which inspired its Latin name meaning twig.

Virga is common in deserts and dry regions where the air beneath clouds is very dry. Mid-level clouds such as altocumulus often produce it. As the drops evaporate, they cool the air, which can sink suddenly and create downbursts that are dangerous to aircraft.

Dry thunderstorms produce lightning with little rain at the surface, raising wildfire risk. Ice virga can create fallstreak holes in cloud layers, and virga even occurs on Venus as evaporating sulfuric acid.
