Rainfall is measured by means of rain gauges..

How does a standard rain gauge work?

Recording of rainfall using the standard or funnel rain gauge is generally done manually. These gauges work by catching the falling rain in a funnel-shaped collector that is attached to a measuring tube. … Magnifying the rain in this way allows precise measurements down to one-hundredth of an inch.

Why is a rain gauge placed 30 cm above the ground?

Prevent the rain gauge from falling over by sinking it into the ground with about 30cm protruding above the ground, or by mounting it such that the rim is at least 30cm above the ground. This will prevent the backsplash from entering the rain gauge. Record the time at which the rainfall events start and end.

What is rain gauge for kids?

Kids Encyclopedia Facts. Standard rain gauge. A rain gauge is an instrument used by meteorologists and hydrologists to measure precipitation (e.g. rain, snow, hail or sleet) in a certain amount of time. It usually measures in millimetres.

What are the advantages of rain gauge?

Answer. The advantages of this type of gauge over tipping buckets are that it does not underestimate intense rain, and it can measure other forms of precipitation, including rain, hail and snow. These gauges are, however, more expensiveand require more maintenance than tipping bucket gauges.

How do you test a rain gauge for accuracy?

Make a pinhole in the bottom of a plastic cup. Hold the cup over the rain gauge and fill it with exactly 1 cup (8 oz.) of water, allowing the water to slowly drip into the rain gauge. You should hear the internal buckets tip and see the water drain through the rain gauge.

How is rain water 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.

What is mean by rain gauge?
