       | Related: Weather apps could in general be better, not just in
       | terms of visualization. One thing which always annoys me is how
       | they handle rain predictions. They give "probabilities" for rain.
       | But what do those mean? The probability that it rains for at
       | least one minute in the given time frame? And with at least x
       | mm/inches of rain coming down? And isn't a low probability of
       | short and weak rain totally different from a equally low
       | probability of strong or long rain?
       | 
       | But there is a perfectly elegant alternative: Just use the
       | _expected amount of rainfall_. The epected value combines both
       | amount and probability of rainfall in one single number, without
       | being highly arbitrary like other approaches, such as the usual
       | reporting of plain  "probabilities" with unclear interpretation.
       | 
       | (Of course one could add to the expected rainfall amount also the
       | variance, to distinguish more certain predictions from more
       | uncertain ones, though this information might often not even be
       | that important.)

         | Expected value is already what most forecasts show. Expected

         | thunderstorms in the summer. It is very different to hear
         | there's a 20% chance of a thunderstorm, dropping an inch of
         | rain, vs. a 100% chance of .2" rain - the former needs a backup
         | plan to deal with rain, the latter needs to plan for rain.
         | Hence I prefer the text forecasts from the NWS, which list an
         | amount possible, plus more in thunderstorms, rather than a bare
         | number.
         | 
         | Meanwhile the 'probability' listed in forecasts is also well
         | defined as an expected value - it's (probability of X% rain
         | coverage) * (X %), over all X. (Rain is defined as > .01")

           | Okay, in very high variance cases like thunderstorms the

           | usually additional storm warnings for that anyway. My claim
           | is just that the expected amount of rainfall is much more
           | interesting than the probability of rainfall. Yet the apps I
           | know display probabilities prominently, not expected values.

         | My understanding is that the probabilities in weather forecasts

         | Local weather models are computed in discrete grid coordinates
         | of say 10km. Every grid cell of 10km^2 has a single set of
         | computed forecast data. The percentage is a measure of how much
         | of that area received rain in the timeframe, not of probability
         | of rain, but of coverage of rain.

         | PRECIPITATION PROBABILITY The probability of precipitation
         | forecast is one of the most least understood elements of the
         | weather forecast. The probability of precipitation has the
         | following features: ..... The likelihood of occurrence of
         | precipitation is stated as a percentage ..... A measurable
         | amount is defined as 0.01" (one hundredth of an inch) or more
         | (usually produces enough runoff for puddles to form) ..... The
         | measurement is of liquid precipitation or the water equivalent
         | of frozen precipitation ..... The probability is for a
         | specified time period (i.e., today, this afternoon, tonight,
         | Thursday) ..... The probability forecast is for any given point
         | in the forecast area To summarize, the probability of
         | precipitation is simply a statistical probability of 0.01" inch
         | of more of precipitation at a given area in the given forecast
         | area in the time period specified. Using a 40% probability of
         | rain as an example, it does not mean (1) that 40% of the area
         | will be covered by precipitation at given time in the given
         | forecast area or (2) that you will be seeing precipitation 40%
         | of the time in the given forecast area for the given forecast
         | time period. Let's look at an example of what the probability
         | does mean. If a forecast for a given county says that there is
         | a 40% chance of rain this afternoon, then there is a 40% chance
         | of rain at any point in the county from noon to 6 p.m. local
         | time. This point probability of precipitation is predetermined
         | and arrived at by the forecaster by multiplying two factors:
         | Forecaster certainty that precipitation will form or move into
         | the area X Areal coverage of precipitation that is expected
         | (and then moving the decimal point two places to the left)
         | Using this, here are two examples giving the same statistical
         | result: (1) If the forecaster was 80% certain that rain would
         | develop but only expected to cover 50% of the forecast area,
         | then the forecast would read "a 40% chance of rain" for any
         | given location. (2) If the forecaster expected a widespread
         | area of precipitation with 100% coverage to approach, but
         | he/she was only 40% certain that it would reach the forecast
         | area, this would, as well, result in a "40% chance of rain" at
         | any given location in the forecast area.
        
           | cubefox wrote:
           | Yeah that definition makes sense. It's indeed the probability
           | you would get at least 0.01" of rain if we assume you are
           | equally likely to be located anywhere in the forecast area.
           | 
           | But for deciding for "getting your jacket", the expected
           | amount of rainfall seems much more relevant. Basically, you
           | don't need a jacket if the rainfall is very unlikely, or
           | weak, or short. In all those cases the expected amount will
           | be low.

         | I tend to use probability more for decision making - usually
         | trying to determine whether I need to bring an umbrella or rain
         | gear with me on a given day. If the probability is low I can
         | usually just look out the window and time my trips outside when
         | it's not raining and probably get by without rain gear. Whereas
         | a high probability means I'm probably going to need to go out
         | in the rain at some point, and need to pack appropriately.
         | 
         | I also do a lot of cycling, and total duration spent in the
         | rain tends to matter more to me than the amount of rainfall. I
         | don't mind riding through a quick downpour or two on a ride if
         | I can dry out in between, but spending several hours in
         | constant rain can be miserable (and hypothermia becomes a
         | concern) - even if it's light rain.
         | 
         | Of course expected amount definitely has uses, too. For example
         | if there is rain forecast for tonight, and I'm trying to
         | determine the probability that a field will be usable for
         | practice in the morning.
         | 
         | Anyway I would say that both probability and expected amount
         | are important, and any competent weather app should offer both.
         | The Apple Weather app only shows hourly forecasts for expected
         | amount, and that alone would be enough to be a dealbreaker for
         | me.

           | a) every big tech company tries to do a ton of stuff. I'm not
           | happy with this weather app. Usually the market would reflect
           | this by me buying a different weather app. However, Apple

           | computer market. If I buy a different weather app, Apple
           | actually gets more money! Buying a different phone because
           | Apple made the decision to kill my favorite weather app is
           | now muddled in with so many other factors and Apple and their
           | shareholders are unlikely to link a drop in phone sales to
           | killing the weather app. Now I also need to look at the very
           | few real competitors and probably have issues with them as
           | well. It's a mess because they all do too much. Maybe I don't
           | want Android devices because Google built Bart without
           | disclosing training sources. What a mess!
           | 
           | b) someone builds something nice and it just gets killed by
           | an incumbant. No real competition between most startups and
           | incumbants. It's more like a buyer/seller relation
           | 
           | I'd love to see this all fixed in my utopia by prohibiting
           | acquisitions and instead force companies to fight for
           | customers. But I'm sure that would need to happen globally to

       | Another Dark Sky thread, another opportunity to ask the community
       | if anyone knows about Apple doing research with the barometers in
       | their phones. Dark Sky claimed they 'did' but they never expanded
       | on what that meant for them. Did they actually use the barometer
       | data collected from the app? Or did it just get sent to /dev/null
       | as I suspect?
       | 
       | And if Apple bought that code, did they use it themselves? Is
       | Apple doing anything to improve weather forecast accuracy in the
       | main weather models by running data assimilation on cleaned
       | barometer data?
       | 
       | If not it is such a wasted opportunity that I just get so angry
       | about. If so....please tell us more.

           | It is absolutely doable.
           | 
           | Especially since you don't actually _need_ raw pressure data

           | 
           | But not only that, the researchers at UW under Cliff Mass
           | found that you can do on-device ML to clean the quality of

           | without even needing the dense network of sensors nearby for
           | error correction.
           | 
           | It's 100% doable, but it just takes some hard science and

           | Yes, but, the noise problem was solved half a decade ago.

           | A 10cm change in elevation at sea level results in a 0.0001%

           | weather-relevant pressure changes operate on scales of ~0.1%

           | 100 meters.
           |

       | 
       | To acquire it just to shut it down would have only made sense to

         | I use Android and never used the nice app, but used the
