Sentences with phrase «linear feedback model»

The paper confirms that realworld observations can be matched by a linear feedback model with a climate sensitivity of something less than1.6 deg K / doubling of CO2.

This first graph shows a spectacularly good (and highly misleading) match of SAT data (Hadcrut3 in this instance) using Callendar's parameters in a single capacity linear feedback model.

Not exact matches

It is definately a non linear scenario as we are talking about mulitple + ve feedbacks in play so a compounding graph will fit the model better.

Dear RC, Is it not possible that scientists and mathematicians from the science of non linear dynamics (which maths I am presuming is being used in the maths of climate models) to shed light on the amplification and dampening of the climates feedback cycles and hence the so called «sensitivity» issue and hence the possible range of temperatures?

So, whilst I agree that the issue is about regime change and not linear feedback, I am not convinced that the models used by climate scientists can not represent the actual system.

One might even find that the output of this complex sytem model could be approximated to a relatively simple linear system with feedback just as complex socioeconomic sytems are often modelled.

Since the industrial revolution, models showing this feedback have been largely linear; however, this linearization is unlikely to hold for temperatures greater than 3 — 4 °C above pre-industrial temperatures.

Did you know that the exact same real world system can be modeled with the exact same feedback as either linear or nonlinear by choice of flow variables?

Accordingly, the forcing estimation method relies upon a model exhibiting a fairly linear climate response, and hence having a climate feedback parameter (and an effective climate sensitivity) that does not vary with time (in addition to having a temperature response that is proportional to forcing).
