Now, that is laughable, that you think you are capable of creating a real climate model.
Wait, I understood that you don't like computer models.
How much abuse did I take on this thread for trying to discuss more accurate modeling in Climate Science based on the tools of various types of System's Theory? And not one poster outside of ItFitzMe even bothered to try to discuss??
New study from Ga Tech posted by Matthew under "Stadium Waves"........
Bottom line first.
Holy cow BatBoy.. Damped deterministic system responses to external forcings. Nonlinear interactions... Any of that ring a bell?
Building upon Wyatt's Ph.D. thesis at the University of Colorado, Wyatt and Curry identified two key ingredients to the propagation and maintenance of this stadium wave signal: the Atlantic Multidecadal Oscillation (AMO) and sea ice extent in the Eurasian Arctic shelf seas. The AMO sets the signal's tempo, while the sea ice bridges communication between ocean and atmosphere. The oscillatory nature of the signal can be thought of in terms of 'braking,' in which positive and negative feedbacks interact to support reversals of the circulation regimes. As a result, climate regimes -- multiple-decade intervals of warming or cooling -- evolve in a spatially and temporally ordered manner. While not strictly periodic in occurrence, their repetition is regular -- the order of quasi-oscillatory events remains consistent. Wyatt's thesis found that the stadium wave signal has existed for at least 300 years.
The new study analyzed indices derived from atmospheric, oceanic and sea ice data since 1900. The linear trend was removed from all indices to focus only the multi-decadal component of natural variability. A multivariate statistical technique called Multi-channel Singular Spectrum Analysis (MSSA) was used to identify patterns of variability shared by all indices analyzed, which characterizes the 'stadium wave.' The removal of the long-term trend from the data effectively removes the response from long term climate forcing such as anthropogenic greenhouse gases.
The stadium wave periodically enhances or dampens the trend of long-term rising temperatures, which may explain the recent hiatus in rising global surface temperatures.
"The stadium wave signal predicts that the current pause in global warming could extend into the 2030s," said Wyatt, an independent scientist after having earned her Ph.D. from the University of Colorado in 2012.
Curry added, "This prediction is in contrast to the recently released IPCC AR5 Report that
projects an imminent resumption of the warming, likely to be in the range of a 0.3 to 0.7 degree Celsius rise in global mean surface temperature from 2016 to 2035." Curry is the chair of the School of Earth and Atmospheric Sciences at the Georgia Institute of Technology.
wave synthesis producing long-lasting DELAYED climate changes??
spectral analysis to identify periodicities?
oscillatory functions and damped responses caused by combos of positive and negative feedback?
the diff between external forcing functions and internal linear and non-linear functions?
Sounds like maybe Curry et al might have listening eh???
Or MAYBE ---- that's just what the science should be saying and doing..
Anyone want to continue discussing OTHER aspects of climate modeling that have been neglected? Or ya just want to badger, insult and harasss???
No one doubts that there are cyclical processes in the climate that account for the obvious variability upon which increasing temperatures are overlain. This is the whole point that is repeatedly made everytime some denier cherry picks a recent and "short lived" downward trend. The fact that there are cyclical processes at work is the whole point of the current insignificant haiatus the ocean cycle is currently in the ocean warming/atmospheric stable trend.
Unfortunately, cycles never account for long term increases. They simply mask the steady upward trend as the negative phase of the cycle offsets that increase. And the problematic part of a cycle is that what one half takes away, the other half gives back.
At this point we can gauge how much that will be and generally when we might expect it. Unfortunately, as nature is a bit messy, being able to say with precision just isn't possible. True sine waves seldom occur in nature. There is, rather, huge "phase noise", where the peaks and valleys are lengthened and foreshortened considerably. It really is this timing issue that makes precise prediction impossible. We know what the total energy is in the system. That can be easily counted. We can count TSI. We can count molecules of CO2.
What we cannot easily count is the timing of the heat moving in waves as it attempts to redistribute itself in a system that is constantly driven by ever changing solar and tidal forces.
The Earth us tilted on its axis, constantly changing the balance of heating, both as the Earth orbits the sun and the Earth revolves on it's axis. As well, the moon orbits the Earth, constantly moving the tide. All this changes where the heat is and where it wants to go. All that thermal energy has momentum and as it moves to cooler locations, it overshoots.
The placement of the continents and oceans are not nicely spaced. The Southpole has a huge lamd mass while the North has none. All of this drives and effects the timing of ocean and atmoshperic cycles is a way that is complex enough to be, for all practical purposes, random in timing.
If the current timing does extend the trough into the 1930's, it won't change the accumulation of heat. It will simply change the timing of when that energy is expressed as atmospheric temperature. And when the cycle gets around to dumping it into the atmosphere, it will do so with a vengance. For every year that temps don't rise, there will be an offsetting year when temps rise at twice the rate. And, we can guarantee that, as that heat has momentum, as it has undershot the mean, it will overshoot the mean as ocean temps drop below the average and the atmosphere overshoots.
Cycles that offset the steady increase are not good on two counts. The first is that rapid increase in atmospheric temps and subsequent overshoot. Crops and species do not adapt all that quickly. The second is the psychological effect that the lull has on people who feel is isn't all that bad.
I am npt sure you are fully grasping the consequences of what these cycles mean.
