Head Office & Display Centre Rain, drops of appreciable size and may be described as small to large drops. Lets take an example of "3mm of rainfall". Mt. If you had a 10x10 meter empty pool before the rain, it would also fill up 3mm. Is it measured per day, per hour, per minute? This height is measured in millimeters and reported. Creating new Help Center documents for Review queues: Project overview.

Use MathJax to format equations.

Days where the rainfall range is larger generally suggest a storm day where anyone under the storm path will receive a lot of rain but others may stay completely dry or get just a few drops. Well, it's saying two different things and you need to break it down into two basic questions: Will it rain today? post multiple versions of the same view or make excessive postings on a particular issue.

I don't think yet another answer is waranted, but I would mention that the actual measurement is made in mm: we measure length, not volume.

It is the middle of July and both you and your tomatoes are wilting in your yard, both looking to the sky and hoping for rain.

In the form below, choose an area(s) and a rainfall amount to see how many gallons of water fell from the sky onto that area. These are two separate pieces of information so take care not to run them together—they don’t mean there is a 70% chance of receiving between 4 and 15 mm of rain. That’s enough to pack the brolly! So there you have it. To learn more, see our tips on writing great answers.

You can also view the 'Chance of any rain' and 'Possible rainfall' in the BOM Weather app. To keep the discussion interesting and relevant, please: We won’t publish comments that are not in line with these standards. So for the forecast above of '4 to 15 mm', Sydney has a 50% chance of receiving 4 mm or more, and a 25% chance of receiving 15 mm or more. How to explain Miller indices to someone outside nanomaterials? The chance of any rain is shown for three-hourly intervals across the day on the main screen (left image, at base). liters) of rain in the gauge can be converted to a theoretical depth of water: 3 mm = 3 liters / square meter Source: WMO Guide to Meteorological Instruments and Methods of Observation. Clovelly Park Open Hours The first figure means there's a 50 per cent chance of receiving at least 2mm of rain. Whenever measurable rainfall is forecast, this field is represented as a range between two values (otherwise it will appear as '0 mm'). Intuitive explanation of precipitation amount, http://www.bom.gov.au/climate/cdo/about/rain-measure.shtml, library.wmo.int/pmb_ged/wmo_8_en-2012.pdf, it can fall in a period much shorter than an hour. 1 l/m2=1mm. Thanks for contributing an answer to Earth Science Stack Exchange! If you assume that rain is essentially pure water, then the weight is directly related to the volume. The only variable is the height. In other words, the volume of rain collected obviously depends on the surface of the ground, but the height of the water level fallen onto the ground does not depend on the surface of the collector. Even when there’s very little likelihood of rain, you'll still see a 'Chance of rain' value, so you can make decisions based on your own threshold for this likelihood. Do you consider it as a light or medium or heavy rain day?

Let's assume a hard water impermeable surface(1mt x 1mt) having a surface area of 1 meter square. The duration is irrelevant with respect to the amount but must be mentioned together with the measurement because it makes a huge difference in meaning and impact: 100 mm in a month are just wet while 100 mm in a day are catastrophic. You can tap to access the detailed forecast, which includes the possible rainfall range (right image) as well as the chance of any rain for the day. The title of the question refers to something different and the only answer to that question is what I am asking an explanation of. Re: How wet is 0.3mm of rain? Did the rain occur in a minute, an hour, or stretch across the entire day.
