When scientists use climate models for attribution studies,
they first run simulations with estimates of only «natural» climate influences over the past 100 years, such as changes in solar output and major volcanic eruptions.

This involves taking the estimates that clients have come up with for what they expect to spend in retirement — and then
running a
simulation of what would happen to their portfolio if they spent 25 % more than that over each of their
first 15 years.
Their
first instinct was to
run simulations involving a planet in a distant orbit that encircled the orbits of the six Kuiper Belt objects, acting like a giant lasso to wrangle them into their alignment.
In August, researchers at the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University
ran a supercomputer
simulation of the early universe and provided a tantalizing glimpse into the lives of the
first black holes.
By
running complex quantum mechanical computer
simulations developed in Ochsenfeld's group, the scientists have now managed for the
first time to explain how the repair enzyme distinguishes between a normal and an oxidized base.
The
first issue is that calculating TCR for each model from historical «All forcing»
runs (histAll) requires using the same
simulations and time periods as used in calculating the forcings.
To investigate cloud — climate feedbacks in iRAM, the authors
ran several global warming scenarios with boundary conditions appropriate for late twenty -
first - century conditions (specifically, warming signals based on IPCC AR4 SRES A1B
simulations).
First, the team
ran detailed
simulations designed to reveal the nature of a circum - Martian disk of debris from which Phobos and Deimos could have coalesced.
Running future
simulations in climate models with present - day emissions, Cai and his colleagues find 73 per cent increase in extreme La Niña events in the twenty -
first century when compared to the twentieth.
For the earlier generation of models, results are based on the archived output from control
runs (specifically, the
first 30 years, in the case of temperature, and the
first 20 years for the other fields), and for the recent generation models, results are based on the 20th - century
simulations with climatological periods selected to correspond with observations.
As an example on IBM stock, the results are respectively with a starting $ 10K investment on January 4, 2010, ending value as of July 2, 2016: 1) $ 13,920.63 2) $ 12,590.00 3) $ 13,242.73 The spread is so wide so I checked my Fidelity Account on a given stock and
ran simulation & calculations... the
first tool yielded ~ +0.4 % more than my stock with Fidelity.
Xbox 360 racing
simulation Forza Motorsport 4 will have limited bonuses for its
first production
run, in which will feature the following exclusive motors:
This is the
first showing, our plan was to get a baseball
simulation running with primitive graphics and to get the gameplay nailed down.
However, I and some colleagues recently looked closely at how well the CMIP5
simulation design has held up (Schmidt et al., 2014) and found that there have been two significant issues — the
first is that volcanoes (and the cooling associated with their emissions) was underestimated post-2000 in these
runs, and secondly, that solar forcing in recent years has been lower than was anticipated.
The effect of slightly increasing the correlation of the
first lag but
running the
simulation as a stationary series is to slightly elongate the typical length scale of the simulated process (Isaaks and Srivastava, p196 et seq show this very elegantly).
The only alternative way around this, if you really want seasons, is to
first run a fully coupled or a slab ocean
simulation and create the SST input data from that.
The
first simulation is an 1860 pre-industrial conditions 500 - year control
run and the second is the SRESA1B, which is a «business as usual» scenario with CO2 levels stabilizing at 720 ppmv at the close of the 21st century [Intergovernmental Panel on Climate Change, 2001].
In the
first study, the research team from PNNL and Los Alamos National Laboratory used idealized global model
simulations of the aquaplanet with Model for Prediction Across Scales - Atmosphere (MPAS - A) and Weather Research and Forecasting Model (WRF) to
run at low, high and variable resolutions.
