Sentences with phrase «observed sea surface temperature changes»

The new finding of the importance of multiple ocean surface temperature changes to the multi-decadal global warming accelerations and slowdowns is supported by a set of computer modeling experiments, in which observed sea surface temperature changes are specified in individual ocean basins, separately.

Taking factors such as sea surface temperature, greenhouse gases and natural aerosol particles into consideration, the researchers determined that changes in the concentration of black carbon could be the primary driving force behind the observed alterations to the hydrological cycle in the region.

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).

The problem here is that estimates of changes in sea surface temperature and the depth of the warm mixed layer might be very unreliable, since the general behavior of the Atlantic circulation is only now being directly observed — and the most recent findings are that flow rates vary over a whole order of magnitude:

Other climate simulations that use sea surface temperature variation didn't match observed changes, either.

Many variables — rainfall, sea surface temperature, fisheries, cyclone frequency — all are observed in empirical evidence — hard data — to change abruptly and for lessor or longer periods.

In his House of Commons presentation, toward the end, he gives a sketch of an alternative derivation of the «Climate Sensitivity» based on observed rates of evaporation increase per change in sea surface temperature, and this based on data from the 2007 paper by Wentz et.

Observed changes in (a) global average surface temperature; (b) global average sea level rise from tide gauge (blue) and satellite (red) data and (c) Northern Hemisphere snow cover for March - April.

The new research uses multiple runs of a coupled ocean - atmosphere computer model to simulate global temperature changes in response to climate forcing when the sea surface temperature (SST) in the el Niño region follows its historically observed values.

Stephen Wilde (00:59:57) «Also one would need to observe the air circulation systems moving latitudinally BEFORE the ocean sea surface temperatures change and I don't think that happens does it?»

Soloman and her co-authors argue that El Niño has been one of the drivers of changes in stratospheric water vapor, noting that «The drop in stratospheric water vapor observed after 2001 has been correlated to sea surface temperature (SST) increases in the vicinity of the tropical «warm pool» which are related to the El Niño Southern Oscillation (ENSO).»

In it, they documented how a change in observing practices before and after World War II produced a cold bias in the sea surface temperatures that were incorporated into the compilations of global average temperatures (see here and here for more details).

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.

The observed patterns of surface warming, temperature changes through the atmosphere, increases in ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of land and sea ice also match the patterns scientists expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).

Natural Variability Doesn't Account for Observed Temperature Increase In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed sinObserved Temperature Increase In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed Temperature Increase In it's press release announcement, NASA points out that while there are other factors than greenhouse gases contributing to the amount of warming observed — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed sinobserved — changes in the sun's irradiance, oscillations of sea surface temperatures in the tropics, changes in aerosol levels in the atmosphere — these factors are not sufficient to account for the temperature increases observed temperature increases observed sinobserved since 1880.
