Continuously variable, electronically controlled shock absorbers provide high damping
force at low frequency vibrations (flat ride) and low damping force at high - frequency vibrations (smooth ride)
Not exact matches
Our conclusions related to the «over-estimated» response could be dealt with using a 2x decrease in the assumed
forcing, or a 2x decrease in the climate sensitivity, or a 2x increase in the
low frequency change in the proxies (although not all
at once!).
This helped to eliminate the chance of post-activation potentiation, which is an increase in muscle twitch and
low -
frequency force after a «conditioning» contractile activity and can be looked
at as a priming mechanism that serves to improve performance (31).
We can not rule out the possibility that some of the
low -
frequency Pacific variability was a
forced response to variable solar intensity and changing teleconnections to higher latitudes that are not simulated by the models, or that non-climatic processes have influenced the proxies... the paleodata - model mismatch supports the possibility that unforced,
low -
frequency internal climate variability (that is difficult for models to simulate) was responsible for
at least some of the global temperature change of the past millennium.»
A substantial component of the
low -
frequency variability in the GKSS simulation, furthermore, appears to have been a «spin - up» artifact: the simulation was initialized from a very warm 20th century state
at AD 1000, prior to the application of preanthropogenic radiative
forcing, leading to a long - term drift in mean temperature (Goosse et al., 2005)....
The justification for this approach is that the CO2
forcing data, since it has no high
frequency content
at all, can not match the high
frequency content in the temperature series, and therefore should be fitted only to the very
low frequency trajectory in the dataset.
Coby: «Milankovic cycles» Actually, the article in question does address the issues you mentioned, but in a very broad way: «The other line of evidence concerns the very clear energy excess
at and about one cycle = 100 ka; where the orbital
forcing is extremely small, but where various hypotheses have been proposed whereby non-linear interactions in the climate system can rectify the higher
frequency forcing into a very large
lower frequency response.»
