Sentences with phrase «upper atmospheric increases»

Not exact matches

Trending increases in certain environmental conditions that brew up these storms: increased sea surface and upper ocean temperatures and atmospheric instability.

OLR increases in the optically thinner bands would lead to atmospheric warming in general, but this has to be accompanied by OLR decreases somewhere, such as in optically thicker bands (and always in the band where optical thickness was added, assuming positive lapse rates everywhere as is the case in a 1 - dimensional equilibrium model with zero solar heating above the tropopause, or at least not too much solar heating in some distributions), which will tend to cause cooling of upper levels.

Given that the other important variables (sea surface temps, depth of the warm layer, and atmospheric moisture) are all predicted to increase, it seems hard to make the claim that tropical cyclones will be unchanged, just as it seemed unwise to claim that Lyman et al's «Recent cooling of the upper oceans» meant that climate models had fatal flaws.

Thus, if the absorption of the infrared emission from atmospheric greenhouse gases reduces the gradient through the skin layer, the flow of heat from the ocean beneath will be reduced, leaving more of the heat introduced into the bulk of the upper oceanic layer by the absorption of sunlight to remain there to increase water temperature.

With no ozone, the atmospheric temperature would decrease monotonically, and we would instead have to speak of cooling of the «upper atmosphere» in conjunction with the surface warming due to increasing GHGs.

In the case where there is a skin temperature that only depends on solar heating of the planet with no solar heating above the troposphere, an increase in GHG forcing would still result in upper atmospheric cooling, but this cooling would only be transient.

Yet, we explained there is also reasonable basis for concern that a warming world may at least temporarily increase tornado damage including the fact that oceans are now warmer, and regional ocean circulation cycles such as La Nina / El Nino patterns in the Pacific which affect upper atmospheric conditions appear to becoming more chaotic under the influence of climate change.

DK12 used ocean heat content (OHC) data for the upper 700 meters of oceans to draw three main conclusions: 1) that the rate of OHC increase has slowed in recent years (the very short timeframe of 2002 to 2008), 2) that this is evidence for periods of «climate shifts», and 3) that the recent OHC data indicate that the net climate feedback is negative, which would mean that climate sensitivity (the total amount of global warming in response to a doubling of atmospheric CO2 levels, including feedbacks) is low.

These assume a continuation of the past exponential growth rate of atmospheric CO2 of around 0.5 % per year despite a dramatic decrease of the population growth rate to less than one - third of the past rate so, even if the world per capita fossil - fuel based energy use increases by 50 %, these are most likely «upper limits» themselves.

The oceans are huge, there is a lot of plant mass which reproduces quickly, is short - lived, and may be growing because of warming and CO2 (and keeping upper ocean CO2 lower than equilibrium with the increased atmospheric concentration).

(Fingerprint studies draw conclusions about human causation that can be deduced from: (a) how the Earth warms in the upper and lower atmosphere, (b) warming in the oceans, (c) night - time vs day - time temperature increases, (d) energy escaping from the upper atmosphere versus energy trapped, (e) isotopes of CO2 in the atmosphere and coral that distinguish fossil CO2 from non-fossil CO2, (f) the height of the boundary between the lower and upper atmosphere, and (g) atmospheric oxygen levels decrease as CO2 levels increase.

Ozone loss in the stratosphere and the consequent increase in penetration of UV into the upper troposphere tends to reduce the differential between the atmospheric pressure in the stationary high pressure cell East of Chile and the low over Indonesia tending to move the atmosphere towards a constant El Nino orientation.

Long - term trends in the upper atmosphere - ionosphere are a complex problem due to simultaneous presence of several drivers of trends, which behave in a different way: increasing atmospheric concentration of greenhouse gases, mainly CO2, long - term changes of geomagnetic and solar activity, secular change of the Earth's main magnetic field, remarkable long - term changes of stratospheric ozone concentration, and very probably long - term changes of atmospheric dynamics, particularly of atmospheric wave activity (Lastovicka 2009; Qian et al. 2011; Lastovicka et al. 2012).

Increased understanding of uncertainties in radiosonde and satellite records makes assessment of causes of observed trends in the upper troposphere less confident than an assessment of overall atmospheric temperature changes.

For more than 10 years (I forgot how much more), upper tropospheric water vapor has not increased in response to significant increases in CO2 atmospheric concentrations.

Since any increase in solar energy would heat both the lower and upper atmosphere, the observed drop in upper atmospheric temperatures in the past 30 years argues against an increase in energy coming from the sun being responsible for global warming.

The latter effect acts to reduce CO2 sensitivity by increasing the aerosol - sensitive SW tau, increasing both cloud density and cover, decreasing upper tropospheric specific humidity and INCREASING SW albedo and will increasingly do so as the atmospheric level of increasing the aerosol - sensitive SW tau, increasing both cloud density and cover, decreasing upper tropospheric specific humidity and INCREASING SW albedo and will increasingly do so as the atmospheric level of increasing both cloud density and cover, decreasing upper tropospheric specific humidity and INCREASING SW albedo and will increasingly do so as the atmospheric level of INCREASING SW albedo and will increasingly do so as the atmospheric level of CO2 rises!

The latter effect acts to reduce CO2 sensitivity by increasing the aerosol - sensitive SW tau, increasing both cloud density and cover, decreasing upper tropospheric specific humidity and SW albedo and will increasingly do so as the atmospheric level of CO2 rises!

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

This behaviour in the upper levels of the models produces a positive feedback which more than doubles the temperature rise calculated to be the consequence of increasing atmospheric CO2.

The average atmospheric water vapour content has increased since at least the 1980s over land and ocean as well as in the upper troposphere.

Even if this hypothesis was at first founded upon assumptions for the absorption of carbon dioxide which are not strictly correct, it is still an open question whether an examination of the «protecting» influence of the higher atmospheric layers upon lower ones may not show that a decrease of the carbon dioxide will have important consequences, owing to the resulting decrease in the radiation of the upper layers and the increased temperature gradient at the earth's surface.
