Not exact matches
These... The
simulation was
actually made from the space engineering CAD [computer - aided design]
models.
Yet, this
model of the quake does not match up well with the information from the ocean floor sensors — incorporating that data into future computer
simulations should give a better picture of what
actually happened during the massive tectonic event.
«As astrophysical observations and
simulations improve, we're doing increasingly precise comparisons between the
models of how galaxies form and the observations of what galaxies
actually look like,» Carroll says.
«Our
model is still incomplete, but the electrical signals produced by the computer
simulation and what was
actually measured in the rat brain have some striking similarities,» says Allen Institute scientist Costas Anastassiou.
From those
simulations they extract reduced - order, or more concise,
models that explain what part of the turbulence
actually makes the sound.
But while the venture is generating knowledge about how to mathematically
model some parts of the brain's circuitry, critics say the
simulation can do very little that is useful or helps us understand how the brain
actually works.
All 114
model simulations overestimate the warming we've
actually experienced (middle graph).
More important, the study suggests that
simulations of liquid water at room temperature with those
models actually describe a supercooled glassy state, not the regular liquid.
Fortunately, over 20
model groups have deposited these
simulations in a public database at PCMDI — and anyone who is
actually interested in seeing what the
models produce can have access (you need to register, but it's just a formality).
This is the first of two pieces on the recent IPCC workshop in Hawaii, This brought together independent researchers from all over the world to analyse computer
model simulations of the last 150 years and to assess whether they are
actually any good.
Additionally, there is little evidence that the rate of conversion of cloud water to rain
actually changes with temperature, although Mauritsen and Stevens show that incorporating the iris into the
model does improve the
model's
simulations of some aspects of the climate system (even though it doesn't change climate sensitivity much).
So the two estimates (with and without solar forcing) give me a range of 0.7 C to 1.4 C for the 2xCO2 climate sensitivity, based on
actually observed CO2 and temperature records, rather than
model simulations and assumptions.
The data which are indicated as having low reliability
actually agree rather too well with the
model simulations, whereas the reconstruction can not closely match the data which are considered precise.»
While I need to get around to
actually publishing this, here in a nutshell is what I think is wrong with climate
model simulations of water vapor feedback.
WebHubTelescope: I know it is hard for those of you that don't
actually do the analysis and simply pontificate on comment sections of blogs, but a
model is different than a
simulation.
It wasn't an unreasonable hypothesis, but with more than 15 year experience in all kinds of electronic circuit
simulations and
model development, the use of a
model to «confirm» the theory left me thinking about how in
model development, you
model how you think something works, and it has no obligation to
actually work like you think.
MONITOR PRODUCTION With weather records,
model simulation, and data collection, authorities can accurately project production levels, compare them with the number of products that
actually end up in the market chain, and see whether supplies exceed the expected totals.
I did see that you're at GISS, you might want to go talk to the
Model E guys,
actually you should suggest they find someone who knows how to code
simulations that are
actually validated, that's things a piece of trash:) It's a good thing you guys are government funded, you'd be out of business if you had to make a living by selling it.
All of the
models are verified against observational data, but in a
model with 10 ** 9 degrees of freedom, it is not always clear how to interpret these verifications, and what elements of the solution are
actually important in terms of the objectives of the
simulation.
