Sentences with phrase «simple climate model simulations»

The model simulates most of the main physical processes in the climate system in a very simplistic way and therefore allows very fast and simple climate model simulations on a normal PC computer.

Some of them are optimal fingerprint detection studies (estimating the magnitude of fingerprints for different external forcing factors in observations, and determining how likely such patterns could have occurred in observations by chance, and how likely they could be confused with climate response to other influences, using a statistically optimal metric), some of them use simpler methods, such as comparisons between data and climate model simulations with and without greenhouse gas increases / anthropogenic forcing, and some are even based only on observations.

Fred, I completely disagree about the relative strength of evidence as to climate sensitivity from simulations by AOCGMs (Chapter 8 of WG1 «Climate Models and Their Evaluation») and from observational evidence that is either direct or intermediated through simple Energy Balance climate sensitivity from simulations by AOCGMs (Chapter 8 of WG1 «Climate Models and Their Evaluation») and from observational evidence that is either direct or intermediated through simple Energy Balance Climate Models and Their Evaluation») and from observational evidence that is either direct or intermediated through simple Energy Balance Models.

Judith, is the distinction Nic makes above between evidence for climate sensitivity «from simulations by AOCGMs... and from observational evidence that is either direct or intermediated through simple Energy Balance Models» relevant to this «structural uncertainty»?

Another strategy is to use a climate model — not a climate simulation like most computer models are, but a simple mathematical model — which includes the affect of ENSO.

While simple comparisons of observations with simulations by climate models have sometimes been used, the most commonly used approach is based on linear regression models (OLS), sometimes assuming error in the predictor (TLS or EIV).

Further, key processes associated with the interactions between aerosols and clouds are either neglected or treated with simple parameterizations in climate model simulations evaluated in the AR4.

Rind's simple model simulation clearly illustrates that changes to Arctic ice alone alter climates the world over.

Simulations with a simple climate model (Schimel et al., 1997) indicate that the global mean temperature response in these profiles is likely to differ by no more than about 0.2 °C from the equivalent WRE profiles (Wigley et al., 1996; see Figure 9.16), though the maximum rate of temperature change is likely to be lower with the S profiles.
