Types of Rainfall
- Convectional rainfall.
- Orographic or relief rainfall.
- Cyclonic or frontal rainfall.
What is the main type of rainfall?
On the basis of origin, rainfall may be classified into three main types – the convectional, orographic or relief and the cyclonic or frontal.
What are the types of rainfall answer?
There are three types of rain that are Convectional rainfall, Orographic or relief rainfall Cyclonic or frontal rainfall.
What are the three types of rainfall on the basis of origin?
On the basis of origin, rainfall may be classified into three main types, convectional, orographic, and cyclonic.
What are the three types of rainfall with diagram?
Solution
- Convectional rainfall: It occurs in the Equatorial regions. The high temperature leads to the rapid heating of air.
- Relief Rainfall: Relief rainfall is also known as Orographic Rainfall.
- Cyclonic Rainfall: This type of rainfall is due to cyclones and depressions.
How many types of rain did we have?
Types of Rainfall – Relief, Convectional, and Frontal Rainfall.
What is Convectional and orographic rainfall?
Convectional or convective rainfall occurs due to thermal convection currents caused by insolation heating of the ground surface. Orographic rainfall occurs due to the accent of air from highland. Cyclonic or frontal rainfall occurs due to upward movement of air caused by convergence of contrasting wind.
What is called rainfall?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls to the Earth.
What are the 4 rainfall characteristics?
The characteristics of rainfall are the amount, the intensity, the duration, the frequency or return period, and the seasonal distribution.
What rainfall means?
a fall or shower of rain
1. a fall or shower of rain. 2. 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.
Why is it called Convectional rainfall?
Convectional rainfall occurs when the energy of the sun (or insolation) heats the earth’s surface and causes water to evaporate changing to water vapor. This warm, moist air then rises, and as it rises, it cools.
What are the three factors affecting rainfall?
The three factors that influence precipitation are the prevailing winds, the seasonal winds, and the presence of mountains. b. Prevailing winds are responsible for moving air masses from one place to another. Because of this, the amount of water vapor in the air masses varies and affects precipitation.
Why is rainfall called Convectional?
This is called convectional rainfall because the moisture and vapor rise and transform in the atmosphere in a movement known as convection.
What is class 3 precipitation?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.
What is called cyclonic rainfall?
Cyclonic rains are caused when the warm moist air comes in contact with cool dry air. At the end of summer, the air above the water heats up and rises creating an area of low pressure. So, the high pressure cold air starts rushing in.
What is mean by orographic rainfall?
Orographic rainfall is precipitation produced when the mountains of uplands act as barriers to airflow, forcing the air to rise and the moist air moving upslope coo down by producing clouds and precipitation.
Is there a blood rain?
It’s understood that blood rain occurs when relatively high concentrations of red coloured dust or particles get mixed into rain, giving it a red appearance as it falls. Blood rain is not actually a meteorological or scientific term – instead it’s a colloquial phrase which can be found going a fair way back in history.
What is light rain called?
Drizzle is light rain falling in fine drops. The drizzle had now stopped and the sun was breaking through. Synonyms: fine rain, spray, Scotch mist, mizzle More Synonyms of drizzle.
What is rainfall and its types?
The types of rainfall based on intensity can be classified as: Light rain – Rate of rain varies between 0 to 2.5 millimeters. Moderate rain – Rate of rain varies between 2.6 millimeters to 7.6 millimeters. Heavy rain – Rate of rain is beyond 7.6 millimeters.
What is another name of convectional rainfall?
4. Such rainfall is known as convectional rainfall which occurs mainly in the northern hemisphere, predominantly in the tropical regions. This type of rainfall is known as cyclonic rainfall and generally occurs in the coastal areas of the world.
What is called conventional rain?
Convectional rainfall seems to occur when the heated air from the earth’s surface rises upwards along with the water vapor & gets condensed when it reaches a higher altitude. Here the clouds carrying the water vapor are not carried away by the wind and hence, it rains in the same place.
