Rain in a bucket?

[Egon]

We don't care if it is 100% accurate. All he asked is if it was fairly close.

And I would say he is close.

For the other stuff. Gravity pulls on the raindrops to make them fall. Raindrop size, wind effects, air resistance and cloud height determine the terminal velocity. The horizontal catchment should collect a representative amount of droplets falling vertically even if they have a horizontal component. If the catchment lip is tilted from the horizontal a reprsentative area is no longer provided. Both horizontal and vertical movement raindrops will be caught. All that should be caught are those under vertical influence.

Calculate the volume of your bucket
Calculate volume of a truncated cone and its surface area

Then find a cylinder height, with the same top diameter, that is the same as the bucket volume.
Calculate volume of a cylinder and its surface area

Or something like that.

Do hills have the same rain per square foot as plains?

Does a walking man get wetter than a running man in 100 feet of travel?

It was raining cats and dogs the other day, do you know how I could tell?

I stepped in a poodle.

Up here it rains ducks and chickens......it's very fowl weather!

Sounds like the roof needs some new Reeds.

If you take a bucket and angle it 90 degrees in any direction, you will find that upon checking it, it didn't' actually rain at all.

Oh Lawdy! Ya'll have cracked me up! I really like the "stepped on a poodle"...lol :laughing:

The bucket is about 10' out from the barn. I had a "rain gauge" some years back but kept forgetting to empty it before a big freeze and it would crack. I sort of like the bucket model, you know like someone asking about what size tractor to buy and everyone says to go a size larger than needed.

Ever see a rain barrel?

Weatherunderground claims we had 3.31 inches in December. That is very suspect as the airport is about 8 miles north of me. I have seen 4.5 inches in my rain guage a few days ago. I know I emptied it once before that and had maybe 3 inches in it. Last night I emptied another inch. Anyhow, in my neighborhood I am betting we had between 7 and 10 inches in the past 7 days. Every creek, stream and river was 2 feet or more above flood stage.

Here is another place you can check statistics but they have not published their December data. National Weather Service Climate

Actually, the bucket method is fairly accurate because with the tapered sides, it takes into account of evaporation loss by the time you read it. Have a great 2016 everybody!

My grandpa certainly bought a bigger rain barrel then needed. He bought a 2,600 gallon tank off a water truck for $200. It is made from 1/2 steel and weighs about 6,000 pounds empty.

Right... I forgot about freezing temperatures and expansion. My 'bad'. The worst I get here is a frost of about -2*C, and that always 'burns off' in a couple of hours after sunrise.

There is a type of in-ground metal gauge that are used by regular folks who report to the bureau of meteorology. Hmmm... <Google: metal rain gauge>

Ah HA! There are heaps of examples and styles available. That just might be your answer, Mate.

I have seen a type of rain gauge that has some sort of deal where the rain goes through it and is measure and it automatically dumps it so it won't stay in and freeze. It doesn't get too cold way down here in Alabama very often. Just enough to be annoying to the Yankees that wander down here....lol. If it gets down to 35F, they ask why we have heavy clothes/jackets on? It's cold! Nahhhh they say, it ain't cold yet!

On Sunday I received between 3 3/4 and 3 7/8 inches of rain at my place as measured in my rain gauge. The five gallon buckets that I had sitting outside that collected water where half full. I didn't measure how deep the water in them was, but would guess it was in the 8 inch range. Given that so much more water ends up in a bucket then what I get in my rain gauge, I think that the bucket is very unreliable to estimating rain fall.

 

[mx1alex]

Technically a 5 gal bucket can be more accurate than your average run of the mill rain gauge. The wider the opening the more accurate it is. NOAA uses an 8' opening on their manual rain gauges and the CoCoRaHS network uses 4" openings.

I'm surprised that no one has mentioned pouring water in the neighbors rain gauge.
