In meteorology, a virga is an observable streak or shaft of precipitation falling from a cloud that evaporates or sublimates before reaching the ground.
What is it called when it rains on one side of the street and not the other?
Yes, It’s basically called a boundary between less saturated and saturated air in the upper and lower atmosphere. Their have been many instances of rain falling on one side of a street, or the distance of 1 block. IT’S sometimes called just a “Freak of Nature”…
What is it called when it rains out of nowhere?
Under certain conditions, rain can fall from the sky without ever reaching the ground. It happens when rain falling from a cloud evaporates or sublimes as it approaches the earth’s surface.
What is it called when rain falls but doesn’t hit the ground?
You often see virga over a desert, where low humidity and high temperatures can cause rain to evaporate shortly after being released by clouds. … Or you might see virga at high altitudes; in fact, the precipitation often starts out in the form of ice crystals.
What is rain in the distance called?
According to the National Weather Service, virga is actually “Precipitation falling from the base of a cloud and evaporating before it reaches the ground.” It’s common enough of a phenomenon that I could picture it when he asked, but if you don’t know what that looks like, check out this image from Wikipedia.
Why does it rain on one side of the mountain?
The protected side of a mountain range is also called the lee side or the down-wind side. … As the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. On this side of the mountains, called the windward side, precipitation falls in the form of rain or snow.
Why does it rain in one spot and not the other?
Moist air, the kind that Florida often experiences, requires minimal cooling to produce condensation — the kind easily induced by a single thermal and capable of raining on a single house but not on an adjacent house, or on just one side of a street.
What causes drizzle?
Drizzle consists of very small raindrops, larger than cloud droplets, but smaller than normal raindrops. It usually occurs when updrafts in clouds are not quite strong enough to produce rain. The clouds that produce drizzle have low bases, usually less than 1,000 feet in altitude.
What is the smell of rain called?
Humans aren’t the only ones to appreciate the earthy aroma after an April rain shower. That smell—known as petrichor—stems from microscopic streptomycete bacteria in the soil that produce a compound called geosmin, The Times reports.
What are the 4 types of rainfall?

- Orographic or relief rainfall.
- Cyclonic or frontal rainfall.
What does word virga mean?
Definition of virga
: wisps of precipitation evaporating before reaching the ground.
What is virga in aviation?
Description. Virga is often seen as a short curtain of rain underneath a cloud. The precipitation falls through warmer air with a higher dew point and evaporates before reaching the surface.
What is evaporating rain called?
The visual phenomenon called virga, a sudden change in the brightness of a precipitation shaft below a cloud, is commonly attributed to evaporation of raindrops. It is said to be rain that does not reach the ground.
What kind of rain is called Senzo?
Answer: This is the season when people use the word sezuo or suzu to refer to the week-long rains, when clothes don’t dry and smell of mould, when fungus forms on the floor and When you can’t see the noon or the stars because of the rainclouds.
What is a rain shaft?
For one, there’s the “rain shaft.” A rain shaft is a centralized column of precipitation—not necessarily heavy rain. … A rain shaft comes out of an individual convective cell, making it roughly five to ten kilometers across. (By contrast, tropical depressions measure roughly 100 to 500 kilometers across.)
What is horizontal rain?
Horizontal precipitation is a phenomenon that has been underestimated for many years. It normally occurs in cloud and montane forests at high elevations where the vegetationcanopy comes in contact with the cloud cover.
