Sentences with phrase «oceanic variability on»

Increasing attention is being paid to IPCC misrepresentations of natural oceanic variability on decadal scales (Compo and Sardeshmukh 2009): «Several recent studies suggest that the observed SST variability may be misrepresented in the coupled models used in preparing the IPCC's Fourth Assessment Report, with substantial errors on interannual and decadal scales (e.g., Shukla et al. 2006, DelSole, 2006; Newman 2007; Newman et al. 2008).

Given these and other misrepresentations of natural oceanic variability on decadal scales (e.g., Zhang and McPhaden 2006), a role for natural causes of at least some of the recent oceanic warming should not be ruled out.»

Climate models provide a means to derive such a link, under the assumption that the current generation of climate models captures the essence of the signature of oceanic variability on the global mean temperature.

«Despite recent advances in the state of the global ocean observing system, estimating oceanic variability on basin - wide to global scales remains difficult.

It is interesting that the North Atlantic does not play a more important role in this largest - trend case, since it does dominate the oceanic variability on somewhat shorter ~ 20 year time scales in this model.

Not exact matches

Monitoring, understanding, and predicting oceanic variations associated with natural climate variability and human - induced changes, and assessing the related roles of the ocean on multiple spatial - temporal scales.

Nature (with hopefully some constructive input from humans) will decide the global warming question based upon climate sensitivity, net radiative forcing, and oceanic storage of heat, not on the type of multi-decadal time scale variability we are discussing here.

The mechanism by which the effect of oceanic variability over time is transferred to the atmosphere involves evaporation, conduction, convection, clouds and rainfall the significance of which has to date been almost entirely ignored due to the absence of the necessary data especially as regards the effect of cloudiness changes on global albedo and thus the amount of solar energy able to enter the oceans.

Requires the Climate Service Program to: (1) analyze the effects of weather and climate on communities; (2) carry out observations, data collection, and monitoring of atmospheric and oceanic conditions; (3) provide information and technical support to governmental efforts to assess and respond to climate variability and change; (4) develop systems for the management and dissemination of data; (5) conduct research to improve forecasting and understanding of weather and climate variability and change and its effects on communities; and (6) develop tools to facilitate the use of climate information by local and regional stakeholders.

This Section places particular emphasis on current knowledge of past changes in key climate variables: temperature, precipitation and atmospheric moisture, snow cover, extent of land and sea ice, sea level, patterns in atmospheric and oceanic circulation, extreme weather and climate events, and overall features of the climate variability.

The problems we are working on range from basic studies of circulation patterns of water in the ocean and groundwater flow systems to the variability of the oceanic circulation under natural and anthropogenically forced conditions or the transport and transformation of contaminants.

Additionally, such an observing system, by measuring the temporal and spatial variability of the AMOC for approximately a decade, would provide essential ground truth to AMOC model estimates and would also yield insight into whether AMOC changes or other atmospheric / oceanic variability have the dominant impact on interannual sea surface temperature (SST) variability.

Natural factors such as the Sun (84 papers), multi-decadal oceanic - atmospheric oscillations such as the NAO, AMO / PDO, ENSO (31 papers), decadal - scale cloud cover variations, and internal variability in general have exerted a significant influence on weather and climate changes during both the past and present.

The oceanic effect is always dominant but the fact is that on 500 year timescales (not necessarily on shorter time scales due to interference from lesser cycles and chaotic variability) the sun is less active as per the Maunder Minimum and at the same the oceans were independently releasing energy at a low rate.

On shorter timescales the background signal is overlain by chaotic variability and lesser solar and oceanic cycles.I'm sure one can find all sorts of contradicting examples on short timescaleOn shorter timescales the background signal is overlain by chaotic variability and lesser solar and oceanic cycles.I'm sure one can find all sorts of contradicting examples on short timescaleon short timescales.

Any variability in oceanic circulation could have strong effects on local, and hence average temperature, even with a fixed energy budget.
