What are the 3 main causes of rainfall?

There are 3 main types of rainfall: relief, frontal and...
  • Relief rainfall occurs when air has been blown over the sea and is then forced up over an area of high land.
  • This causes the air to cool and the moisture in the air condenses and rain falls.

Which is stronger rain or showers?

Showers, also known as rain showers, have a shorter duration than rain. ... Compared to rain, showers cover a smaller area but can be more intense. Cumulonimbus clouds (thunderstorm clouds) produce the heaviest rainfalls. Showers from stratocumulus clouds (not as puffy) tend to not be so heavy.

What is known as rain gauge?

A rain gauge (also known as an udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined area, over a period of time.

Is rain a drizzle?

Rain: Precipitation in the form of liquid water drops that have diameters greater than 0.5 millimeter; if less than 0.5 millimeter, it is drizzle. Rain and drizzle are the only forms of liquid precipitation.

What is orographic rain?

Orographic precipitation, rain, snow, or other precipitation produced when moist air is lifted as it moves over a mountain range. As the air rises and cools, orographic clouds form and serve as the source of the precipitation, most of which falls upwind of the mountain ridge.

What is rainfall explain?

Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.

What is a relief rainfall?

Relief rainfall occurs when warm moist air from the Atlantic Ocean rises up over mountains. When the warm air rises, it cools and condenses to form clouds, which bring rain. Once the air has passed over the mountains, it descends and warms. This creates drier conditions known as a rain shadow .

What is rainfall answer?

noun. a fall or shower of rain. the amount of water falling in rain, snow, etc., within a given time and area, usually expressed as a hypothetical depth of coverage: a rainfall of 70 inches a year.

What type of rainfall is most common in the UK?

So frontal rainfall can fall anywhere. It is the most common type of rainfall in the UK. The warm air mass slides up over the cold one, or gets pushed up by it.

What type of rainfall is more common in India and why?

Most of India's rainfall is convectional. The convectional rainfall is prevalent in equatorial regions. In these, the warm air rises up and expands then, reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds.

How is rainfall caused?

What causes rain? Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.

Is drizzle worse than light rain?

Drizzle drops tend to be small, falling much slower than rain. On the other hand, rain drops are bigger and fall slightly faster. Interesting fact: Believe it or not any drop which has a diameter of 0.5 mm or less, is generally considered to be drizzle while larger than that is considered to be rain.

What is light rain vs rain?

Key Difference: Light rain is basically light precipitation that falls from the sky which covers a large area and commonly falls from stratus clouds. Now, rain showers are shorter in duration and they cover a small area. ... They tend to be quick and come in bursts and fall from puffy cumuliform clouds.

How many inches of rain is a drizzle?

Drizzle is classified as light, falling at a rate from a trace to 0.01 inch per hour; moderate, 0.01 to 0.02 inch per hour; heavy, greater than 0.02 inch per hour. Other terms such as steady rain and downpour are informal and do not carry meteorological definitions.

What is rain gauge class 9?

1.3 Rain gauge. A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area. The instrument consists of a collection container which is placed in an open area. ... During rain, rain water is collected in the collecting bucket, through the funnel.

Who invented rain gauge?

The first standardized rain gauge was invented in 1441 in Korea. In 1662 the first tipping bucket rain gauge was invented in Britain by Christopher Wren and Robert Hooke. The first systematic rainfall measurements were done between 1677 and 1694 by Richard Townley in Britain.

What is the uses of rain gauge?

OBJECTIVE: Make and use a rain gauge, an instrument used to collect and measure precipitation (falling water). It measures the depth of the water that would cover the ground if the rain did not drain away or evaporate.

What is a light rain shower?

On the other hand, rain showers are considered to be light rainfall that has a shorter duration than rain, and is more scattered across an area. (When you hear “showers” think of an actual shower bath).

How long is a shower of rain?

What is rain shower head?
