Does all rain hit the ground?
1. Phantom rain. 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.
How common is virga?
It is very common in deserts and temperate climates. In North America, it is commonly seen in the Western United States and the Canadian Prairies. It is also very common in the Middle East, Australia, and North Africa.
Are virga clouds rare?
Yes, they are. Virga clouds are amongst the rarest cloud formations, according to The Weather Channel. Part of the reason they are not often spotted is the type of climate they need to form. Deserts are sparsely populated and where virga is most likely to appear.
What is falling rain called?
Precipitation Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
What are the different types of rain?
Types of Rainfall
- Convectional rainfall.
- Orographic or relief rainfall.
- Cyclonic or frontal rainfall.
What is Phantom rain?
Virga, also called phantom rain, is precipitation that evaporates before it hits the ground. It often appears as wispy, gray streaks radiating from clouds, and is most common in desert environments.
Does virga cause turbulence?
However, on some occasions, virga can lead to the development of microbursts, which pose a dangerous threat to planes and aircraft. These microbursts come about as rainfall transitions back into water vapour, removing heat from the air and causing an accelerating sink of colder air, which can cause severe turbulence.
Why does virga happen?
You may have seen it happening as a storm rolls in, in the form of virga. Virga is rain that evaporates before it hits the ground. It happens when rain falls through an especially dry part of the atmosphere which generally saturates from the upper atmosphere down to the surface.
Where is virga common?
Virga is commonly seen in the U.S. West and above the Canadian prairies, in the Middle East, Australia and North Africa. At some northerly latitudes, too – as in the photos from Sweden on this page – virga sometimes paints the sky above. The word virga is derived from Latin meaning “twig” or “branch”.
What are different types of rain?
The different types of precipitation are:
- Rain. Most commonly observed, drops larger than drizzle (0.02 inch / 0.5 mm or more) are considered rain. …
- Drizzle. Fairly uniform precipitation composed exclusively of fine drops very close together. …
- Ice Pellets (Sleet) …
- Hail. …
- Small Hail (Snow Pellets) …
- Snow. …
- Snow Grains. …
- Ice Crystals.
What are the three types of rain?
There are three rainfall types: Convectional rainfall. Orographic or relief rainfall. Cyclonic or frontal rainfall.

What are the three types of rainfall explain?
The types of rainfall based on intensity can be classified as: Light rain – Rate of rain varies between 0 to 2.5 millimetres. Moderate rain – Rate of rain varies between 2.6 millimetres to 7.6 millimetres. Heavy rain – Rate of rain is beyond 7.6 millimetres.
Is virga safe to fly through?
In most cases, you can see through the virga. When should you avoid virga? If the temperatures aloft are at or below freezing, virga can contain supercooled liquid water, and flying through it is an icing hazard.
Which is a hazard associated with virga?
As you might expect, virga are associated with precipitation that does not reach the ground, often happening in isolated locations on sometimes, the finest of days. However, on some occasions, virga can lead to the development of microbursts, which pose a dangerous threat to planes and aircraft.
What does a virga look like?
Virga looks like cirrus cloud wisps falling from the base of other clouds. Clouds exhibiting virga can also go by the name jellyfish clouds. You also might hear virga be interchanged with the term fallstreak (hence the term fallstreak hole).

Are there different kinds of rain?
Scientists recognize four different kinds of raindrops as well as four different types of rainfall. Temperature gradients and air moisture content are the main determinants of the characteristics of the raindrops that fall at a particular time and place. On the other hand, wind patterns and topography govern rainfall.
How many types of rainfall give name?
There are three types of rain that are Convectional rainfall, Orographic or relief rainfall Cyclonic or frontal rainfall.
Which is a hazard associated with Virga?

What causes Virga?
Virga is essentially precipitation that evaporates before it reaches the ground. Virga begins as actual precipitation falling from clouds, but encounters a sufficiently thick layer of dry air, causing the precipitation to evaporate. As a result, you see the precipitation as wisps dangling from the clouds.

What are three types of rain rainfall?
The basic definition of rain says water that is liquidized from the aqueous vapour in the atmosphere and falls on the earth in drops. It has a diameter of more than 0.02 inches. There are three types of rain that are Convectional rainfall, Orographic or relief rainfall Cyclonic or frontal rainfall.
Is Graupel a snow?
Graupel is also called snow pellets or soft hail, as the graupel particles are particularly fragile and generally disintegrate when handled. Sleet are small ice particles that form from the freezing of liquid water drops, such as raindrops.
