Sentences with phrase «longer equilibrium response»

It's also possible that a lower TCR would simply indicate a longer equilibrium response time.

Not exact matches

A GCM with relatively low transient response but relatively high equilibrium sensitivity probably has large thermal inertia, therefore will take longer to equilibrate, and vice versa.

The disequilibrium referred to comes from the fact that the ocean has a lot of thermal inertia and takes a long time to warm up, whereas the atmosphere has a short response time and quickly comes into equilibrium with any given ocean temperature, corresponding to the current amount of greenhouse gases.

Starting from an old equilbrium, a change in radiative forcing results in a radiative imbalance, which results in energy accumulation or depletion, which causes a temperature response that approahes equilibrium when the remaining imbalance approaches zero — thus the equilibrium climatic response, in the global - time average (for a time period long enough to characterize the climatic state, including externally imposed cycles (day, year) and internal variability), causes an opposite change in radiative fluxes (via Planck function)(plus convective fluxes, etc, where they occur) equal in magnitude to the sum of the (externally) imposed forcing plus any «forcings» caused by non-Planck feedbacks (in particular, climate - dependent changes in optical properties, + etc.).)

Physically, C1 can be thought of as representing the concentration of CO2 in long - term stores such as the deep ocean; C1 + C2 as representing the CO2 concentration in medium - term stores such as the thermocline and the long - term soil - carbon storage; and C = C1 + C2 + C3 as the concentration of CO2 in those sinks that are also in equilibrium with the atmosphere on time scales of a year or less, including the mixed layer, the atmosphere itself and rapid - response biospheric stores.

The equilibrium climate response to anthropogenic forcing has long been one of the dominant, and therefore most intensively studied, uncertainties in predicting future climate change.

The longer term sensitivity he means needs feedbacks that are slower than the response of the ocean to come up to an approximate thermal equilibrium.

This is particularly true for a long term response to CO2 forcing, because of the major role of the deep ocean (down to 4000 meters and even below) in long term heat storage needed for equilibrium.

For a slow feedback climate sensitivity of 6 C for doubled CO2, the equilibrium temperature response would be expected to take much longer (at least several millennia), since this response has been shown to be a strong function of climate sensitivity (Hansen et al., 1985).
