How does a rain gauge work?
A rain gauge is really just a cylinder that catches rain. If an inch collects in the cylinder, it means an inch of rain has fallen. It’s that simple. Most standard rain gauges have a wide funnel leading into the cylinder and are calibrated so that one-tenth of an inch of rain measures one inch when it collects inside.
How do you gauge rain?
Here’s what you’ll need to do:
- Measure the diameter of the bucket at the level of the rain.
- Measure the diameter of the bucket at the bottom in the same way.
- Calculate the average of the two diameters.
- Divide by two to find the average radius.
- Find the average volume of rain = Depth x radius x radius x 3.14.
What is a rain gauge how does it work Class 7?
The rain gauge is also known as an udometer, pluviometer, or an ombrometer. It measures the rain in a localized area. To measure the rain, rain gauges should be placed in an outer area where there are no obstacles like buildings or trees or other things to block the rain.
What is rain gauge and its types?
There are two types of rain gauges, non-recording type and recording type. Rain gauge is a type of instrument used by meteorologists and hydrologists to measure rainfall rate in a certain period of time. Rain gauges are also known as udometer, pluviometer and ombrometer.
What is the importance of rain gauge?
A rain gauge is an important tool to help monitor global weather patterns, aid farmers dealing with drought and help meteorologists prepare for natural disasters.
What is the unit of rain gauge?
millimetres
Most modern rain gauges generally measure the precipitation in millimetres in height collected during a certain period, equivalent to litres per square metre. Previously rain was recorded as inches or points, where one point is equal to 0.254 mm or 0.01 of an inch.
What is rain gauge in hydrology?
A raingauge is the most basic hydrological instrument. In its simplest form the gauge may be a bucket collecting falling rain or snow. This is manually emptied and the depth of water that has accumulated since it was last emptied is noted.
What are the 10 uses of rain gauge?
The function or rather uses of rain gauge are as follows:
- To measure the fluid amount in a defined precipitated space over time reference.
- This principle enables to know the amount of precipitation over an area.
- Pluviometer reads the amount of rainfall of an area.
- It also helps to critically mark drought areas.
