What is a rain thermometer used for?
A rain gauge is a meteorological instrument to measure the precipitating rain in a given amount of time per unit area.
What is a rain measuring device called?
A rain gauge (also known as udometer, pluvia metior, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over an area in a predefined area, over a period of time.
How do you measure the temperature of rain?
Instruments. 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 rain gauges work?
These gauges work by catching the falling rain in a funnel-shaped collector that is attached to a measuring tube. The area of the collector is 10 times that of the tube; thus, the rain gauge works by magnifying the liquid by a factor of 10.
What does a rain gauge look like?
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 measure rainfall at home?
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.
How do you make a rain meter?
Making a Rain Gauge
- Cut the top section off a clear bottle as shown.
- Place several small rocks in the bottom (for weight), then fill the bottle with water to the 0 mark.
- Invert the top of the bottle into to rain gauge to act as a funnel.
- Wait for the next rain and observe and record rainfall amounts.
How do you make a rain measuring device?
Make a rain gauge Carefully cut around the plastic bottle about two-thirds of the way up. Pour in 100ml water and mark it all the way round to create a flat starting point for measurement. Turn the top part of the bottle upside down (take the lid off!) and place it inside the bottom part. Fix it in place with tape.
