Sentences with phrase «change in surface temperature»

I like the definition of climate sensitivity as «change in surface temperature per unit change in radiative forcing».

Hence, relatively small exchanges of heat between the atmosphere and ocean can cause significant changes in surface temperature.

(Note: this relies on the earth coming back into radiative balance via changes in surface temperature).

The increase helped trigger the most extreme change in surface temperatures since dinosaurs ruled the land.

Therefore, climate change is the negative system response whereby changes in circulation within an increased or decreased atmospheric volume effectively prevent changes in surface temperature.

They do this via changes in the surface temperature.

Hence, relatively small exchanges of heat between the atmosphere and ocean can cause significant changes in surface temperature.

To predict changes in surface temperatures in the coming decades, scientists use global climate models (GCMs), which offer a general overview of future trends in surface temperature, but not reliable regional details that can cause extreme temperatures.

Figure 6 - 2: Seasonal change in surface temperature from 1880 - 1889 to 2040 - 2049 in simulations with aerosol effects included.

Here are some model results of change in surface temperature for changes in specific humidity at different heights:

Four multi-decadal climate shifts were identified in the last century coinciding with changes in the surface temperature trajectory.

An international team of university and NASA scientists examined the relationship between changes in surface temperature and vegetation growth from 45 degrees north latitude to the Arctic Ocean.

The short - term change in surface temperature over the 2000 - 2010 period is a result of ocean heat being exchanged with the atmosphere (via ENSO).

Consistent with observed changes in surface temperature, there has been an almost worldwide reduction in glacier and small ice cap (not including Antarctica and Greenland) mass and extent in the 20th century; snow cover has decreased in many regions of the Northern Hemisphere; sea ice extents have decreased in the Arctic, particularly in spring and summer (Chapter 4); the oceans are warming; and sea level is rising (Chapter 5).

Four multi-decadal climate shifts have been identified in the last century coinciding with changes in the surface temperature trajectory.

For example, Kosaka and Xie showed than when the El Niño - related changes in Pacific ocean temperature are entered into a model, it not only reproduced the global surface warming over the past 15 years but it also accurately reproduced regional and seasonal changes in surface temperatures.

As I pointed out on another thread, you can get a large change in surface temperature with only a small change in τ.

Dessler finds that the short - term changes in surface temperature are related to exchanges of heat to and from the ocean - which tallies well with what we know about El Niño and La Niña, and their atmospheric warming / cooling cycles.

The Spencer / Braswell and Lindzen / Choi papers have an unusual take on global warming: rather than warming causing a change in cloud cover (i.e. acting as a feedback to either increase or reduce warming), both papers claim that it's the other way around - changes in cloud cover cause changes in the surface temperature (in the present case, warming).

That illustrates my point, which is that present changes in surface temperature is not a good indicator of what we should expect in the future, and as such, it is not a great idea to make the debate about the observed ocean temperature.

Changes in surface temperature send thermal waves underground, cooling or warming the subterranean rock.

Shifts can be relatively minor or can involve major change in surface temperature, hydrology or biology in as little as a decade.

Legates says a Canadian climate model that plaintiffs cite to show potential changes in surface temperatures and moisture across North America is «extreme» and «overstated.»

I agree that reduction in snow or ice cover resulting from warming constitutes a likely slow positive feedback, but its magnitude may be quite small, at least for the modest changes in surface temperature that can be expected to arise if sensitivity is in fact fairly low, so the Forster / Gregory 06 results may nevertheless be a close approximation to a measurement of equilibrium climate sensitivity.

Positive Trend in the Antarctic Sea Ice Cover and Associated Changes in Surface Temperature: Journal of Climate: Vol 30, No 6

The dramatic differences between regional and hemispheric / global past trends, and the distinction between changes in surface temperature and precipitation / drought fields, underscore the limited utility in the use of terms such as the «Little Ice Age» and «Medieval Warm Period» for describing past climate epochs during the last millennium.

Forgetting the theory for a moment, it is easy to relate the observed change in surface temperature to the sort of observed change in atmospheric CO2 from 1850 to today, assuming

Changes over land that modify its evaporative cooling can cause large changes in surface temperature, both locally and regionally (see Boxes 7.1, 7.2).

In the next few years, we should be able to completely refute the argument that solar fluctuations are a primary reason for the change in surface temperatures.

Fortunately, thanks to the Miata's famously communicative chassis, you can feel this change in surface temperatures.

where H is the heat content of the land - ocean - atmosphere system and T ′ is the change in surface temperature in response to a change in heat content.....

While Spencer hypothesizes that the changes in cloud cover are the main driver behind global warming, Dessler concludes that they're only responsible for a small percentage of the changes in surface temperature from 2000 to 2010.

I clearly see that the change in surface temperature and TOA radiative forcing simulated by the model depends upon the model complexity, for example, how the ocean circulations are represented.

But the change in surface temperature would also cause a change in radiative forcing.
