    Update on the contest. I contacted Met Eireann about the verification of snow depths at Casement. So far I haven't heard back. I will wait until 10 November and if I haven't resolved that issue, I will let all contestants know that we are switching the location. You may then adjust your prediction if you wish.

    Hi MT, I know it's been a hectic few days, but is there any change of location for the snow forecast?

    Thanks

    Did you notice I mentioned getting a virus a few days ago (in my computer, not my head)? One of the nasty things it did was to send most of my e-mail to trash without me getting to read it. Thus I may have missed met's reply to my request about Casement, as I missed about half a dozen other expected e-mails last week. The odd thing is, the virus quite likely jumped in from that storm thread (a post had a link that I thought was going to be storm pictures and turned out to be total spam).

    Well, I have renewed my request for information on Casement's elusive snowfall (if any) and if we don't get resolution by the 18th, I will go with Danno's generous offer and give all contestants notice and adequate time to review their prediction for his somewhat different exposure (although I would have to think that the climatology numbers are about the same). In my case, I haven't posted an entry yet, but here goes (and my snowfall would remain the same for either).

    DEC 2.5
    JAN 2.4
    FEB 2.6
    mean 2.5

    PRECIP - Dec 120%
    Jan 110%
    Feb 60%

    mean 97%

    Temp extremes 13.5 and -13.8

    Extreme wind gust 79 kn

    Snowfall 67 cms

    Just posted my long-range forecast in the winter thread, that will give a rationale for my madness. I think the winter could be even colder than what's predicted here but this should do for now.

    Follks, its not possible to get an accumulated snowfall over such a long period. Not in Ireland anyway, which often operates on the borderline between night-ice and day-melt for much of the winter.

    Think about it. Met Eireann measures snow on the ground, which melts. 5 cm of snow today probably won't be 5cm tomorrow.

    Best start coming up with an alternative measure........

  • Registered Users Posts: 14,331 ✭✭✭✭M.T. Cranium


    Well, it is true that my concept of snowfall is based on North American and not (evidently) European practice. Over here, what we do is to measure snowfall each day, actually at 3-hour intervals, keeping a record of snow depths that accumulate (temporarily in some cases) and then summing those up daily, monthly and seasonally. This is what is meant when somebody (routinely) quotes the annual average snowfall at say Chicago to be 35" or whatever it is. In all likelihood, that 35" implies that perhaps 10-15" might be on the ground at a maximum at any time in the winter, but everyone in weather circles knows that 35" means a total snowfall for the season and includes such variables as freeze-thaw, drifting, different moisture ratios etc.

    So I mistakenly thought that European stations measured the same thing and apparently they do things differently, as confirmed by an e-mail I just got, and there is no such thing as a "seasonal snowfall total" but there could be one, of course, if somebody kept track of it. Now Danno told me earlier that he measures snowfall routinely when it happens (which being in southern Laois might not be quite as often as elsewhere?) ... so what I would say here is, look at your prediction, imagine what therefore might be the right answer for Durrow in Laois rather than Casement, and if you want to adjust your figure, then go ahead and do so.

    You don't have to resubmit the whole forecast, just post a new snowfall total for the season. If you are prepared to stick with your original forecast, then would you take a moment to "thank" this post and that will tell us (me and Hellboy99) that you are staying with the original.

    Now, the forecast contest closes at the end of play on the 18th (Thursday) but I will check the files and see who hasn't either signed off or changed, and send those people a note giving them to end of Sunday to change just the snowfall if they wish.

    Sorry about the confusion. Perhaps if your climate shifts to something colder you too will know the thrills and joys of regular snowfall measurement. It's odd that the two different systems evolved, you would think the WMO would have standardized something like this years ago, but evidently not.

    In reality, I think the snowfall estimates will probably stand or fall on the basis of about five to ten individual snowfall events that we could have estimated from snow depths reported from Casement, so I will try to keep a running estimate of what that might be just for comparison purposes. For example, in North American practice, let's say it's raining with snow mixing in and nothing sticks on the ground, then the snowfall might be reported as trace or even 0.1 cm or some small amount, but if the snow were to stick for a few hours and then melt, it would get into the records as the full amount that fell even though that might not be on the ground even at the end of that day. As I explained earlier, snowfall in these climates tends to stick around longer so that your daily end-of-day snowdepth reflects to a fairly consistent degree the new snow that has fallen that day, but with some settling. For example, if we had ten inches on the ground at some snowy location, and the day produced six new inches, the snow depth would very likely be something like 13-14 inches due to settling and compaction. So using snow depths especially in a more marginal climate would lead to problems in this measurement.

    Here's the official WMO guide to Instruments and Methods of Observation. Snow depths is in Chapter 6, page 148.
    6.7 Measurement of snowfall and snow cover

    The authoritative texts on this topic are
    WMO (1994) and WMO (1992a), which cover the
    hydrological aspects, including the procedures,
    for snow surveying on snow courses. The following
    is a brief account of some simple and
    well-known methods, and a brief review of the
    instrumentation.

    Snowfall is the depth of freshly fallen snow deposited
    over a specified period (generally 24 h). Thus,
    snowfall does not include the deposition of drifting
    or blowing snow. For the purposes of depth
    measurements, the term “snow” should also
    include ice pellets, glaze, hail, and sheet ice
    formed directly or indirectly from precipitation.
    Snow depth usually means the total depth of
    snow on the ground at the time of observation.
    The water equivalent of a snow cover is the vertical
    depth of the water that would be obtained by
    melting the snow cover.

    6.7.1 Snowfall depth

    Direct measurements of the depth of fresh snow on
    open ground are taken with a graduated ruler or
    scale. A sufficient number of vertical measurements
    should be made in places where drifting is considered
    absent in order to provide a representative
    average. Where the extensive drifting of snow has
    occurred, a greater number of measurements are
    needed to obtain a representative depth. Special
    precautions should be taken so as not to measureany previously fallen snow. This can be done by
    sweeping a suitable patch clear beforehand or by
    covering the top of the old snow surface with a
    piece of suitable material (such as wood with a
    slightly rough surface, painted white) and measuring
    the depth accumulated on it. On a sloping
    surface (to be avoided, if possible) measurements
    should still be taken with the measuring rod vertical.
    If there is a layer of old snow, it would be
    incorrect to calculate the depth of the new snow
    from the difference between two consecutive measurements
    of total depth of snow since lying snow
    tends to become compressed and to suffer
    ablation.

    6.7.2 Direct measurements of snow
    cover depth

    Depth measurements of snow cover or snow accumulated
    on the ground are taken with a snow
    ruler or similar graduated rod which is pushed
    down through the snow to the ground surface. It
    may be difficult to obtain representative depth
    measurements using this method in open areas
    since the snow cover drifts and is redistributed
    under the effects of the wind, and may have
    embedded ice layers that limit penetration with a
    ruler. Care should be taken to ensure that the
    total depth is measured, including the depth of
    any ice layers which may be present. A number of
    measurements are taken and averaged at each
    observing station.
    A number of snow stakes, painted with rings of
    alternate colours or another suitable scale,
    provide a convenient means of measuring the
    total depth of snow on the ground, especially in
    remote regions. The depth of snow at the stake
    or marker may be observed from distant ground
    points or from aircraft by means of binoculars or
    telescopes. The stakes should be painted white
    to minimize the undue melting of the snow
    immediately surrounding them. Aerial snow
    depth markers are vertical poles (of variable
    length, depending on the maximum snow depth)
    with horizontal cross-arms mounted at fixed
    heights on the poles and oriented according to
    the point of observation.
    The development of an inexpensive ultrasonic
    ranging device to provide reliable snow depth measurements
    at automatic stations has provided a
    feasible alternative to the standard observation,
    both for snow depth and fresh snowfall (Goodison
    and others, 1988). This sensor can be utilized to
    control the quality of automatic recording gauge
    measurements by providing additional details on
    the type, amount and timing of precipitation. It is
    capable of an uncertainty of ±2.5 cm.

    6.7.3 Direct measurements of snow
    water equivalent

    The standard method of measuring water equivalent
    is by gravimetric measurement using a snow
    tube to obtain a sample core. This method serves as
    the basis for snow surveys, a common procedure in
    many countries for obtaining a measure of water
    equivalent. The method consists of either melting
    each sample and measuring its liquid content or by
    weighing the frozen sample. A measured quantity
    of warm water or a heat source can be used to melt
    the sample.
    Cylindrical samples of fresh snow may be taken
    with a suitable snow sampler and either weighed or
    melted. Details of the available instruments and
    sampling techniques are described in WMO (1994).
    Often a standard raingauge overflow can be used
    for this method.
    Snowgauges measure snowfall water equivalent
    directly. Essentially, any non-recording precipitation
    gauges can also be used to measure the water
    equivalent of solid precipitation. Snow collected
    in these types of gauges should be either weighed
    or melted immediately after each observation, as
    described in section 6.3.1.2. The recording-weighing
    gauge will catch solid forms of precipitation as
    well as liquid forms, and record the water equivalent
    in the same manner as liquid forms (see
    section 6.5.1).
    The water equivalent of solid precipitation can also
    be estimated using the depth of fresh snowfall. This
    measurement is converted to water equivalent by
    using an appropriate specific density. Although the
    relationship stating that 1 cm of fresh snow equals
    the equivalent of 1 mm of water may be used with
    caution for long-term average values, it may be
    highly inaccurate for a single measurement, as the
    specific density ratio of snow may vary between
    0.03 and 0.4.
    6.7.4 Snow pillows
    Snow pillows of various dimensions and materials
    are used to measure the weight of the snow that
    accumulates on the pillow. The most common
    pillows are flat circular containers (with a diameter
    of 3.7 m) made of rubberized material and filled
    with an antifreeze mixture of methyl alcohol and
    water or a methanol-glycol-water solution. The
    pillow is installed on the surface of the ground,flush with the ground, or buried under a thin layer
    of soil or sand. In order to prevent damage to the
    equipment and to preserve the snow cover in its
    natural condition, it is recommended that the site
    be fenced in. Under normal conditions, snow
    pillows can be used for 10 years or more.
    Hydrostatic pressure inside the pillow is a measure
    of the weight of the snow on the pillow. Measuring
    the hydrostatic pressure by means of a float-operated
    liquid-level recorder or a pressure transducer
    provides a method of continuous measurement of
    the water equivalent of the snow cover. Variations
    in the accuracy of the measurements may be
    induced by temperature changes. In shallow snow
    cover, diurnal temperature changes may cause
    expansion or contraction of the fluid in the pillow,
    thus giving spurious indications of snowfall or
    snow melt. In deep mountain areas, diurnal temperature
    fluctuations are unimportant, except at the
    beginning and end of the snow season. The access
    tube to the measurement unit should be installed
    in a temperature-controlled shelter or in the ground
    to reduce the temperature effects.
    In situ and/or telemetry data-acquisition systems
    can be installed to provide continuous measurements
    of snow water equivalent through the use of
    charts or digital recorders.
    Snow pillow measurements differ from those taken
    with standard snow tubes, especially during the
    snow-melt period. They are most reliable when the
    snow cover does not contain ice layers, which can
    cause “bridging” above the pillows.
    A comparison of the water equivalent of snow
    determined by a snow pillow with measurements
    taken by the standard method of weighing shows
    that these may differ by 5 to 10 per cent.

    6.7.5 Radioisotope snowgauges

    Nuclear gauges measure the total water equivalent
    of the snow cover and/or provide a density profile.
    They are a non-destructive method of sampling and
    are adaptable to in situ recording and/or telemetry
    systems. Nearly all systems operate on the
    principle that water, snow or ice attenuates radiation.
    As with other methods of point measurement,
    siting in a representative location is critical for
    interpreting and applying point measurements as
    areal indices.
    The gauges used to measure total water content
    consist of a radiation detector and a source, which
    is either natural or artificial. One part (for example,
    the detector/source) of the system is located
    at the base of the snowpack, and the other at a
    height greater than the maximum expected snow
    depth. As snow accumulates, the count rate
    decreases in proportion to the water equivalent
    of the snowpack. Systems using an artificial source
    of radiation are used at fixed locations to obtain
    measurements only for that site. A system using
    naturally occurring uranium as a ring source
    around a single pole detector has been successfully
    used to measure packs of up to 500 mm of
    water equivalent, or a depth of 150 cm.
    A profiling radioactive snowgauge at a fixed
    location provides data on total snow water
    equivalent and density and permits an accurate
    study of the water movements and density
    changes that occur with time in a snowpack
    (Armstrong, 1976). A profiling gauge consists of
    two parallel vertical access tubes, spaced
    approximately 66 cm apart, which extend from a
    cement base in the ground to a height above the
    maximum expected depth of snow. A gamma ray
    source is suspended in one tube, and a scintillation
    gamma-ray detector, attached to a photomultiplier
    tube, in the other. The source and detector are set
    at equal depths within the snow cover and a
    measurement is taken. Vertical density profiles of
    the snow cover are obtained by taking
    measurements at depth increments of about
    2 cm. A portable gauge (Young, 1976) which
    measures the density of the snow cover by
    backscatter, rather than transmission of the
    gamma rays, offers a practical alternative to
    digging deep snow pits, while instrument
    portability makes it possible to assess areal
    variations of density and water equivalent.

    6.7.6 Natural gamma radiation

    The method of gamma radiation snow surveying is
    based on the attenuation by snow of gamma radiation
    emanating from natural radioactive elements
    in the top layer of the soil. The greater the water
    equivalent of the snow, the more the radiation is
    attenuated. Terrestrial gamma surveys can consist
    of a point measurement at a remote location, a
    series of point measurements, or a selected traverse
    over a region (Loijens, 1975). The method can
    also be used on aircraft. The equipment includes
    a portable gamma-ray spectrometer that utilizes a
    small scintillation crystal to measure the rays in a
    wide spectrum and in three spectral windows
    (namely, potassium, uranium and thorium emissions).
    With this method, measurements ofgamma levels are required at the point, or along
    the traverse, prior to snow cover. In order to obtain
    absolute estimates of the snow water equivalent, it
    is necessary to correct the readings for soil moisture
    changes in the upper 10 to 20 cm of soil for
    variations in background radiation resulting from
    cosmic rays, instrument drift and the washout of
    radon gas (which is a source of gamma radiation)
    in precipitation with subsequent build-up in the
    soil or snow. Also, in order to determine the relationship
    between spectrometer count rates and
    water equivalent, supplementary snow water
    equivalent measurements are initially required.
    Snow tube measurements are the common reference
    standard.
    The natural gamma method can be used for
    snowpacks which have up to 300 mm water
    equivalent; with appropriate corrections, its
    precision is ±20 mm. The advantage of this
    method over the use of artificial radiation sources
    is the absence of a radiation risk.

    Please note, midnight tonight is the deadline for entries.

    If you haven't seen my post a few days ago, and you are already entered, please note a change in location for the snowfall measurements. You have the option to change your snowfall forecast up to the end of Sunday 21st.

    I will be sending a PM to all contestants who have not thanked the post (as a way of saying no changes) or made their changes known.

    Good luck and may the coldest, snowiest forecast win! :D

    Rebelbrowser, we'll accept your entry, and any others submitted this weekend. Anyone has the right to amend submitted forecasts until midnight Sunday. I am reminding people also that the snowfall measuring site will be Danno's IWN weather station located near Durrow. Anyone wishing to amend their earlier Casement prediction has to the end of the weekend.

    Firm deadline now -- Sunday 2401 GMT (or 0001 Monday really).

    Should be either a pile of snow or a pile of fun, and in some cases, both. :cool:

    And the referee blows his whistle ... entires are now closed, in response to the request for amendments on snowfall, please note one change by PM ...

    Homolumo is now going for 30 cms.

    The notified contestants have the rest of Monday to respond, quite a few have let me know they are sticking with the original forecasts, so just waiting for one or two to make this official.

    Hellboy99 has kindly provided his services and has a nifty table ready to place in the thread when we have the entries finalized.

    We'll try to keep the thread updated with relevant stats but as most of you are regulars in the monthly contest, you already know where those are available anyway.

    Good luck to all our contestants (looks like about two dozen).
