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.
How Do You Measure Rain?
How do you measure rain? It is a question that is often asked by those who are curious about the processes involved in understanding and predicting rainfall.
Rainfall is one of the most important elements of the Earth‘s climate and is an essential part of the hydrological cycle.
In order to measure rain accurately, several different methods are available. The most common method of measuring rainfall is by using a rain gauge.
Rain gauges are typically placed at different locations where rainfall is to be measured. These gauges measure the amount of water that falls in a certain area over a period of time.
This type of gauge usually consists of a funnel connected to a measuring cylinder or container. The amount of water that collects in the container is then measured and recorded.
Another common method of measuring rainfall is through the use of a radar system. Radar systems use radio waves to detect the presence of rain.
The radio waves are reflected off of the raindrops and then detected by the radar system. The amount of radio waves that are reflected can then be measured and used to determine the amount of rain that is falling.
Satellites can also be used to measure rainfall. These satellites are equipped with instruments that measure the amount of water vapor in the atmosphere.
