Sentences with phrase «natural oceanic processes»

Not exact matches

It is clearly established that climate variability affects the oceanic content of natural and anthropogenic DIC and the air - sea flux of CO2, although the amplitude and physical processes responsible for the changes are less well known.

Here we present a means to estimate this natural flux by a separation of oceanic carbon anomalies into those created by biogenic processes and those created by CO2 exchange between the ocean and atmosphere.

I propose the following Climatic null hypothesis that: «Natural climatic variation is quantified by the stochastic uncertainty envelope of historical and paleo data, embodying the nonlinear chaotic interaction of atmospheric, oceanic, volcanic, solar, and galactic processes, including climate persistence quantified by Hurst - Kolmogorov dynamics.»

«Natural climatic variation is quantified by the stochastic uncertainty envelope of historical and paleo data, embodying the nonlinear chaotic interaction of atmospheric, oceanic, volcanic, solar, and galactic processes, including climate persistence quantified by Hurst - Kolmogorov dynamics.»

In the meantime, their results have tentatively breathed a small hint of life back into the climate models, basically buying them a bit more time — time for either the observed temperatures to start rising rapidly as current models expect, or, time for the modelers to try to fix / improve cloud processes, oceanic processes, and other process of variability (both natural and anthropogenic) that lie behind what would be the clearly overheated projections.

Variability associated with these latter processes, generally referred to as natural long - term climate variability, arises primarily from changes in oceanic circulation.

I will certainly be making the point about the downturn in temperatures worldwide, and their connection with natural processes such as the major oceanic oscillations.

Topics that I work on or plan to work in the future include studies of: + missing aerosol species and sources, such as the primary oceanic aerosols and their importance on the remote marine atmosphere, the in - cloud and aerosol water aqueous formation of organic aerosols that can lead to brown carbon formation, the primary terrestrial biological particles, and the organic nitrogen + missing aerosol parameterizations, such as the effect of aerosol mixing on cloud condensation nuclei and aerosol absorption, the semi-volatility of primary organic aerosols, the importance of in - canopy processes on natural terrestrial aerosol and aerosol precursor sources, and the mineral dust iron solubility and bioavailability + the change of aerosol burden and its spatiotemporal distribution, especially with regard to its role and importance on gas - phase chemistry via photolysis rates changes and heterogeneous reactions in the atmosphere, as well as their effect on key gas - phase species like ozone + the physical and optical properties of aerosols, which affect aerosol transport, lifetime, and light scattering and absorption, with the latter being very sensitive to the vertical distribution of absorbing aerosols + aerosol - cloud interactions, which include cloud activation, the aerosol indirect effect and the impact of clouds on aerosol removal + changes on climate and feedbacks related with all these topics In order to understand the climate system as a whole, improve the aerosol representation in the GISS ModelE2 and contribute to future IPCC climate change assessments and CMIP activities, I am also interested in understanding the importance of natural and anthropogenic aerosol changes in the atmosphere on the terrestrial biosphere, the ocean and climate.
