Instruments for measuring precipitation include rain gauges and snow gauges, and various types are manufactured according to the purpose at hand. Rain gauges are discussed in this chapter. Rain gauges are classified into recording and non-recording types.
How Is Precipitation Measured?
Precipitation is one of the most important weather variables, and measuring it is crucial for understanding the water cycle. There are many different ways to measure precipitation, each with its own advantages and disadvantages.
The most common way to measure precipitation is with a rain gauge. Rain gauges come in many different shapes and sizes, but they all work on the same principle.
They collect rainfall in a funnel and then measure the depth of the water in the funnel. This can be done either manually or electronically.
Manual rain gauges are the simplest and most inexpensive type of rain gauge. They are often used in schools and by amateur meteorologists.
They are not as accurate as other types of rain gauges, but they are a good way to get a general idea of rainfall amounts. Electronic rain gauges are more expensive than manual ones, but they are much more accurate.
They use sensors to measure rainfall amounts and then send the data to a computer. This data can then be used to produce precipitation maps.
Another way to measure precipitation is with a weather radar. Radar works by sending out a pulse of energy and then measuring how long it takes for the energy to bounce back. The time it takes for the energy to bounce
