  Continental climate - Wikipedia, the free encyclopedia
A continental climate is the climate typical of the middle-latitude interiors of the large continents of the [Northern Hemisphere] in the zone of westerly winds; similar climates exist along the east coasts and southwest coasts of the same continents, and also at higher elevations in certain other parts of the world.
This climate is characterized by winter temperatures cold enough to support a fixed period of stable snow cover each year, and relatively moderate precipitation occurring mostly in summer, although east coast areas (chiefly in North America) may show an even distribution of precipitation.
In Europe these climates may grade off into oceanic climates in which the influence of moderating air masses is more marked toward the west.

 Oceanic climate - Wikipedia, the free encyclopedia
An oceanic climate (also called marine west coast climate and maritime climate) is the climate typically found along the west coasts at the middle latitudes of all the world's continents, and in southeastern Australia; similar climates are also found at coastal tropical highlands and tropical coasts on leeward sides of mountain ranges.
Oceanic climates are characterized by a narrower annual range of temperatures than are encountered in other places at a comparable latitude, and differ from Mediterranean climates in that significant amounts of precipitation are received in summer.
Overall temperature characteristics vary among oceanic climates; those at the lowest latitudes are subtropical from a thermal standpoint, but more commonly a mesothermal regime prevails, with cool, but not cold, winters and warm, but not hot, summers.

 Climate - Facts, Information, and Encyclopedia Reference article
Climate in a narrow sense is usually defined as the “average weather”, or more rigorously, as the statistical description in terms of the mean and variability of relevant quantities over a period of time ranging from months to thousands or millions of years.
When the original conception of climate as a long-term average came to be considered, perhaps towards the end of the 19th century, the idea of climate change was not current, and a 30 year average seemed reasonable (but see note 1).
Climate indices are generally identified or devised with the twin objectives of simplicity and completeness, and each typically represents the status and timing of the climate factor they represent.

 France CLIMATE   (Site not responding. Last check: 2007-10-14)
The oceanic climate, prevailing in the western parts of the country, is one of small temperature range, ample rainfall, cool summers, and cool but seldom very cold winters.
The continental (transition) type of climate, found over much of eastern and central France, adjoining its long common boundary with west-central Europe, is characterized by warmer summers and colder winters than areas farther west; rainfall is ample, and winters tend to be snowy, especially in the higher areas.
The Mediterranean climate, widespread throughout the south of France (except in the mountainous southwest), is one of cool winters, hot summers, and limited rainfall.

 WHOI : Oceanus : Computer Modelers Stimulate Real and Potential Climate, Work Toward Prediction
The change in oceanic conditions associated with ENSO is usually accompanied by atmospheric shifts, and together these phenomena lead to droughts in some parts of the world and flooding in others.
Another climate variation, the North Atlantic Oscillation (NAO), a shift of atmospheric pressure fields between Iceland (65°N) and the Azores (40°N) on decadal time scales, is known to change weather conditions in Europe and North America (see NAO inset in Clara Deser's article).
Climate prediction models must prove they can describe observed climate evolutions in the past before they can be trusted for future predictions.

 NCDC: Global Warming
Many natural phenomena are climate dependent (such as the growth rate of a tree for example), and as such, provide natural 'archives' of climate information.
Large and rapid climatic changes affecting the atmospheric and oceanic circulation and temperature, and the hydrological cycle, occurred during the last ice age and during the transition towards the present Holocene period (which began about 10,000 years ago).
Climate models are constantly improving based on both our understanding and the increase in computer power, though by definition, a computer model is a simplification and simulation of reality, meaning that it is an approximation of the climate system.

 Climate - Land and Resources - France - Europe
The climate of France is generally temperate with three major variations: oceanic, continental, and Mediterranean.
The climate of any particular region of the country is largely determined by the dominant of these three influences in the region, although elevation and other local conditions are also important.
The oceanic climate prevails throughout much of the country, especially in the north and west, where westerly winds from the Atlantic Ocean bring mild and moist conditions.

 Global Warming: Limitations of General Circulation Models and Costs of Modeling Efforts
To improve predictions of the future climate, modelers are also striving to couple, and to some degree have coupled, (1) the land surface to the atmosphere and (2) the Antarctic sea ice to both the ocean and the atmosphere.
Oceanic models have also simulated the general circulation of the ocean, including the patterns of the principal currents.
This research--through which models of the global climate are improved, tested, and, in some cases, used to project the future climate and the ways it may change--can be grouped into two broad areas: modeling to predict changes in climate that may occur over decades and centuries, and modeling to simulate the current climate.

 Carbon Balance and Management | Full text | Projected climate change impact on oceanic acidification   (Site not responding. Last check: 2007-10-14)
Ocean warming or circulation alterations induced by climate change has the potential to slowdown the rate of acidification of ocean waters by decreasing the amount of CO uptake by the ocean [2].
With climate change, we project by 2100 that the surface ocean DIC concentration is 18% less than the control experiment (reduction in DIC growth from 135 μmol/kg to 110 μmol/kg; see Figure 1c).
This insensitivity to climate change occurs because the decrease in pH due to warming is nearly equal to but opposite in magnitude to the pH increase associated with reduced growth of DIC concentration in the upper ocean caused by reduced solubility of CO with ocean warming (Figure 2).

 WHOI : Ocean and Climate Change Institute : Abrupt Climate Change: Should We Be Worried?   (Site not responding. Last check: 2007-10-14)
Most of the studies and debates on potential climate change, along with its ecological and economic impacts, have focused on the ongoing buildup of industrial greenhouse gases in the atmosphere and a gradual increase in global temperatures.
These disruptions may be exacerbated because the climate changes occur in a direction opposite to what is commonly expected, and they occur at a pace that makes adaptation difficult.
Thus, the climate of the North Atlantic region may rapidly return to one that more resembles today’s—even as other parts of the world, particularly less-developed regions, experience the unmitigated brunt of global warming.

 Atlas: Oceanic climate variability at millennial and orbital time scales : Latitudinal versus longitudinal climate ...   (Site not responding. Last check: 2007-10-14)
However the oceanic link fails to take into account the observation that climate variability on millennial time scales also appears in equatorial and sub-tropical latitudes of the Pacific and the Indian oceans, showing various response in amplitude of the climate signal.
Moreover, recent climate studies based on ENSO climate variability have suggested possible inter-basin climate connections, which involve the tropical areas as possible trigger for climate changes in the northern latitudes through changes in the hydrologic cycle.
Considering the state of knowledge about interhemispheric climate links and tropical climate variability, various climate records (based on marine sediments) from sub-tropical areas are reported in order to see what can be learned about latitudinal and longitudinal climate connections associated with rapid climate changes of the last glacial period.

Understanding and quantifying natural climate variability is important, among other things, for properly assessing the magnitude of anthropogenic climate change.
For a longer time scale climate behavior, oceanic processes are bound to play an important role due, in part, to ocean’s large inertia and enormous capacity to store heat and carbon dioxide.
If certain climate modes are dominated by a low number of degrees of freedom, they may be partially predictable.

Indeed, estimating the impact of carbon injection is complicated because of a limited understanding of climate and oceanic carbon cycle feedback mechanisms.
To investigate the possible effects of feedbacks between global climate change, the ocean carbon cycle and oceanic carbon sequestration, Jain and graduate student Long Cao developed an atmosphere-ocean, climate-carbon cycle model of intermediate complexity.
Future climate change could affect both the uptake of carbon dioxide in the ocean basins and the ocean circulation patterns themselves, Jain said.
