  2. Measure the diameter of the bucket at the bottom in the same way.
  3. Calculate the average of the two diameters.
  4. Divide by two to find the average radius.
  5. Find the average volume of rain = Depth x radius x radius x 3.14.

What is the best way to measure rainfall?

The most accurate way to measure rainfall is to take a rain bucket of a known diameter (usually 12 or 24 inches) and place it on a scale . The scale subtracts the mass of the container from the mass of the rain.

How the rainfall is measured?

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 we measure rainfall answer?

Precipitation gauges (or raingauges if only liquid precipitation can be measured) are the most common instruments used to measure precipitation. Generally, an open receptacle with vertical sides is used, usually in the form of a right cylinder, with a funnel if its main purpose is to measure rain.

How is rain measured at home for kids?

A rain gauge is a simple measurement tool that tells you how much rain has fallen over a period of time. Start with creating a rain gauge with the kids. Choose periods of time to measure rain fall and then check it against official measurements from the National Weather Service’s website.

What does 10 cm rainfall mean?

Usually we measure liquid in terms of volume, like one gallon, or one liter. Volume is really just 3 units of length multiplied by each other. For example, 1 liter is 1000 cm^3, or if you would like to think of a cube of water, it would be 10 cm by 10 cm by 10 cm. The volume is 10*10*10 = 1000 cm^3.

Is code for rain gauge?

6.5 Raingauge of appropriate capacity as specified in IS 5225 shall be used to ensure the measurement of extremes of rainfall in the event of the observer being unable to take observations repeatedly on the day of such heavy rainfall.

How do you read rainfall data?

The most common rainfall measurement is the total rainfall depth during a given period , expressed in millimeters (mm). For instance, we might want to know how many millimeters of rain fell over the course of 1 h, 1 day, 1 month, or 1 year.

What is rainfall unit?

The most common rainfall measurement is the total rainfall depth during a given period, expressed in millimeters (mm) . For instance, we might want to know how many millimeters of rain fell over the course of 1 h, 1 day, 1 month, or 1 year.

How do you calculate rainfall per area?

Find the average volume of rain = Depth x radius x radius x 3.14 . Find the area at the top of the bucket (this is the area over which the rain is collected). Divide the rainfall volume by this area to get the rainfall.

What’s a rain gauge for kids?

A rain gauge is a simple measurement tool that tells you how much rain has fallen over a period of time . Start with creating a rain gauge with the kids. Choose periods of time to measure rain fall and then check it against official measurements from the National Weather Service’s website.

Where should I put my rain gauge?

Location! Keep your rain gauge in open areas as far away from obstacles as possible , whether trees, houses, or fences. Having your gauge level is another great way to keep the readings accurate. This will help rain from splashing out and to help with winds blowing.

What household items can you use to make a rain gauge?

  • Empty two-liter plastic bottle.
  • Scissors.
  • A few handfuls of clean pebbles, gravel, or marbles.
  • Masking tape.
  • Water.
  • Ruler.
  • Permanent marker.
  • Rainy weather.

What does 1 mm of rain look like?

So 1 mm of rain translates to 1 litre of water in a single metre square . So 802 mm of rain would mean that a single metre square would receive 802 litres of rain, 140 mm would mean 140 litres of water received in a single metre square, and so on.

Is 2 cm of rain a lot?

Slight rain: Less than 0.5 mm per hour. Moderate rain: Greater than 0.5 mm per hour, but less than 4.0 mm per hour. ... Moderate shower: Greater than 2 mm, but less than 10 mm per hour. Heavy shower: Greater than 10 mm per hour, but less than 50 mm per hour.
