Rain is droplets of water that fall from clouds. Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. Big, heavy droplets falling to the ground are called rain, and small droplets are called drizzle.
We’ve all seen virga, but maybe not known what it’s called. Virga is rain that evaporates before it hits the ground.
does all rain come from the ocean? A good bit of the rain that falls over land comes from the oceans. Eventually, some of that water makes its way back to the oceans, beginning the cycle all over again. Earth’s water cycle is complicated. The water vapor then rises into the sky, where it condenses to form clouds.
People also ask, how is rain formed short answer?
Answer : The rain is formed the process of Precipitation. In this process the water vapour rises up in the the atmosphere and it cools down to form water droplets. These water droplets then turn into clouds then they all combine together and grow bigger and when they become too heavy they falls on earth as Rain.
What causes Virga?
It occurs when the surface air is dry, causing the precipitation to evaporate in mid-air. This means that virga is most commonly seen in desert areas, such as the southwestern US.
What happens when rain hits the ground?
When it rains, where does it go? Once on the land, rainfall either seeps into the ground or becomes runoff, which flows into rivers and lakes. The rate of rainfall: A lot of rain in a short period tends to run off the land into streams rather than soak into the ground.
What is the word for rain that doesn’t hit the ground?
In meteorology, a virga is an observable streak or shaft of precipitation falling from a cloud that evaporates or sublimates before reaching the ground. A shaft of precipitation that does not evaporate before reaching the ground is a precipitation shaft.
Can clouds touch the ground?
Some clouds are high up in the sky. Low clouds form closer to Earth’s surface. In fact, low clouds can even touch the ground.
What is dry rain?
Dry rain, or “Virga” is a weather related phenomenon that occurs when precipitation evaporates before it hits the ground. It is often visually striking and looks like a torn drape hanging
What is the scientific name for rain?
Nimbus—“Nimbus” comes from the Latin word for “rain.” Whenever there is precipitation there are nimbus clouds.
Can you see rain in the distance?
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 is Virga dangerous?
Most pilots have been taught to stay away from virga. However, not all virga is dangerous. Virga is produced when snow or rain is falling from the base of the cloud, but evaporates in dry air before reaching the surface. The heavier air tends to accelerate toward the earth producing a downdraft.
What does Virga look like?
Virga is the name given to precipitation (usually rain) that evaporates or sublimes before it hits the ground. It tends to look like wispy gray streaks hanging underneath the base of a cloud.
What causes heavy rain?
Causes of Heavy Rain Rain occurs when the water vapor “held” in warm, moist air condenses into liquid water and falls. For heavy rain, the amount of moisture in the air mass must be disproportionately large compared to its size.
Where is rain formed?
Rain is droplets of water that fall from clouds. Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds.
How is rain measured?
The standard instrument for the measurement of rainfall is the 203mm (8 inch) rain gauge. This is essentially a circular funnel with a diameter of 203mm which collects the rain into a graduated and calibrated cylinder. The measuring cylinder can record up to 25mm of precipitation.
Is rain a noun?
rain used as a noun: Any matter moving or falling, usually through air, and especially if liquid or otherwise figuratively identifiable with raindrops. An instance of particles or larger pieces of matter moving or falling through air.
What is the process of rain called?
The water cycle describes how water evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.
How is rain made?
Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.
