Sentences with phrase «seasonal climate forcing»

While the local, seasonal climate forcing by the Milankovitch cycles is large (of the order 30 W / m2), the net forcing provided by Milankovitch is close to zero in the global mean, requiring other radiative terms (like albedo or greenhouse gas anomalies) to force global - mean temperature change.

I have a special interest in plankton interactions with the physical environment; looking for quantitative and mechanistic links to current structure, water mass shifts, seasonal cycles, interannual variability, climate - related signals, wind forcing, etc..

These orbital variations, which can be calculated from astronomical laws (Berger, 1978), force climate variations by changing the seasonal and latitudinal distribution of solar radiation (Chapter 6).

The community [studying] seasonal and longer climate variability was (and still is) dominated by the ocean community and especially a decade ago [the El Niño Southern Oscillation] ENSO was the only boundary forcing that anyone was paying attention to.

Although the primary driver of glacial — interglacial cycles lies in the seasonal and latitudinal distribution of incoming solar energy driven by changes in the geometry of the Earth's orbit around the Sun («orbital forcing»), reconstructions and simulations together show that the full magnitude of glacial — interglacial temperature and ice volume changes can not be explained without accounting for changes in atmospheric CO2 content and the associated climate feedbacks.

Climate modelers are very thankful for the existence of the seasonal cycle, for providing such a beautiful data set with which we can test a models quantitative response to a well - defined change in external forcing.

The U.S. military seems interested in climate variations / change on timescales from seasonal to scales out to about 30 years, a period over which natural climate variability could very well swamp anthropogenically forced climate change.

A top - down climate effect that shows long - term drift (and may also be out of phase with the bottom - up solar forcing) would change the spatial response patterns and would mean that climate - chemistry models that have sufficient resolution in the stratosphere would become very important for making accurate regional / seasonal climate predictions.

What I actually said — and have always said — is that if the net of * all * feedbacks in the climate system is negative, then a mere seasonal and spatial reorganisation of TSI under orbital forcing would not be capable of terminating glacials.

Halloran, A., 2012: Growing Uncertainties: Climate change is forcing farmers in the Northeast to rethink their seasonal strategies.

«There is evidence of an emerging pattern of climate response to forcing by greenhouse gases and sulfate aerosols... from the geographical, seasonal and vertical patterns of temperature change... These results point toward a human influence on global climate.»

Crespin, E., Goosse, H., Fichefet, T., Mairesse, A. & Sallaz - Damaz, Y. Arctic climate over the past millennium: Annual and seasonal responses to external forcings.

Comparing the influences on the Last Interglacial climate with those assumed in future climate projections is problematic owing to fundamental differences, especially orbital forcing, seasonal warming, and greenhouse gas concentrations.

The new low ice cover state has been sampled predominantly in summer - autumn and seasonal forcing combined with internal climate variability are likely responsible for triggering recent transitions between the two ice cover states.

I came to think of solar radiation as being the ultimate (and only) external forcing of the climate system, which, except for the orbital seasonal changes and the 11 - year sunspot cycle, has been essentially constant over the past several decades of precision solar irradiance monitoring.

A recent study by C10 analysed a number of different climate variables in a set of SMEs of HadCM3 (Gordon et al. 2000, atmosphere — ocean coupled version of HadSM3) from the point of view of global - scale model errors and climate change forcings and feedbacks, and compared them with variables derived from the CMIP3 MME. Knutti et al. (2006) examined another SME based on the HadSM3 model, and found a strong relationship between the magnitude of the seasonal cycle and climate sensitivity, which was not reproduced in the CMIP3 ensemble.

Recent analyses using the CCM3 climate model (Govindasamy and Caldeira, 2000) suggest, however, that a 1.7 % decrease in solar luminosity would closely counterbalance a doubling of CO2 at the regional and seasonal scale (in addition to that at the global and annual scale) despite differences in radiative forcing patterns.»
