Sentences with phrase «for atmospheric heat»

Though Newton's Second law, dealing with mass inertia, does not apply directly to the AGW argument it brings attention to the fact that our atmosphere not only has enormous mass inertia but the thermodynamic analog: thermal inertia, whereby it takes time, lots of it, for atmospheric heat to build to detectable levels.

Another principal investigator for the project, Laura Pan, senior scientist at the National Center for Atmospheric Research in Boulder, Colo., believes storm clusters over this area of the Pacific are likely to influence climate in new ways, especially as the warm ocean temperatures (which feed the storms and chimney) continue to heat up and atmospheric patterns continue to evolve.

The UM Rosenstiel School researchers used historical observations of cloud cover as a proxy for wind velocity in climate models to analyze the Walker circulation, the atmospheric air flow and heat distribution in the tropic Pacific region that affects patterns of tropical rainfall.

As a result of atmospheric patterns that both warmed the air and reduced cloud cover as well as increased residual heat in newly exposed ocean waters, such melting helped open the fabled Northwest Passage for the first time [see photo] this summer and presaged tough times for polar bears and other Arctic animals that rely on sea ice to survive, according to the U.S. Geological Survey.

Therefore, the strongest motivation for the current scientific review is the need for a synoptic organization of the available knowledge on the field of interactions at different planetary systems, in parallel with a comparative analysis encompassing the inter-connection among planetary space weather aspects belonging to different disciplines (e.g. plasma variability and its effects on atmospheric heating).

For example, in Earth atmospheric circulation (such as Hadley cells) transport heat between the warmer equatorial regions to the cool polar regions and this circulation pattern not only determines the temperature distribution, but also sets which regions on Earth are dry or rainy and how clouds form over the planet.

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

The ability of a large moon such as Titan to subsequently retain a substantial atmosphere for billions of years depends on a delicate balance between surface gravity, atmospheric molecular mass, and solar heating.

If more heat is transferred to the oceans than is accounted for by the models, that «is a negative atmospheric feedback, at least on shorter time scales.»

TRUTH: Only a small percentage of atmospheric methane comes from ruminant flatulence; the largest source is the burning of fossil fuels for electricity, heat, and transportation.

For about two years now, an atmospheric ridge of high pressure in the northeastern Pacific has blocked out storms and high winds, allowing the sun to heat a 2,000 - mile stretch of ocean stretching from the Gulf of Alaska to Mexico.

For instance, there is no evidence that, with the current configuration, atmospheric heat transports have vastly different modes of behaviour — and so they are unlikely to suddenly flip into a new state.

Explanations for the recent «pause» in SST warming include La Niña - like cooling in the eastern equatorial Pacific, strengthening of the Pacific trade winds, and tropical latent heat anomalies together with extratropical atmospheric teleconnections.

[Response: Much of the power for the hurricanes comes from latent heat: the condensation of atmospheric moisture as air parcels are raised.

The natural process of atmospheric blocking, and the climate impacts induced by such blocking, are the principal cause for this heat wave.

The advantage of the ocean heat content changes for detecting climate changes is that there is less noise than in the surface temperature record due to the weather that affects the atmospheric measurements, but that has much less impact below the ocean mixed layer.

The radiative balance over equilibrium timescales — the heat released by raindrop formation will locally warm the atmosphere, but it takes time for the atmospheric circulation to average this out.

For hurricanes, then, you'd want to ask what the sea surface temperature, subsurface ocean heat content, and atmospheric water vapor content would have been if, say, fossil fuel use had been eliminated 100 years ago, and atmospheric CO2 remained at about 300 ppm.

For example, see The partitioning between atmospheric and oceanic heat transport is not trivial.

Two climatologists, Peter Stott at the British Met Office and Kevin Trenberth of the National Center for Atmospheric Research, have separately described atmospheric dynamics that appear to link the extreme rains and flooding in Asia with Russia's unrelenting, extraordinary heat and resulting conflagrations.

It seems that predictions are for less oceanic heat transport and more atmospheric (latent / moist) heat transport.

Of course, there are plenty of negative feedbacks as well (the increase in long wave radiation as temperatures rise or the reduction in atmospheric poleward heat flux as the equator - to - pole gradient decreases) and these (in the end) are dominant (having kept Earth's climate somewhere between boiling and freezing for about 4.5 billion years and counting).

I do not think atmospheric temperatures are a consistent and precise proxy for the total heat content of the global system.

I have shown that the heat emissions are four times the amount accounted for in the actual measured rise in atmospheric temperature.

Due to the huge volume of sea water and the density differentials between air and ocean that would be impossible or would require such huge amounts of atmospheric heating and such huge lengths of time that for practical purposes it should be ignored.

I am very disappointed that you did not point out that heat emissions alone are more than sufficient to account for all the rise in atmospheric temperature as well as increase in ocean heat content that we have witnessed.

However, because climate scientists at the time believed a doubling of atmospheric CO2 would cause a larger global heat imbalance than today's estimates, the actual climate sensitivities were approximatly 18 % lower (for example, the «Best» model sensitivity was actually closer to 2.1 °C for doubled CO2).

However, as in the FAR, because climate scientists at the time believed a doubling of atmospheric CO2 would cause a larger global heat imbalance than current estimates, the actual «best estimate» model sensitivity was closer to 2.1 °C for doubled CO2.

Instead, land surface models were originally developed to provide lower boundary fluxes of momentum, heat and water for existing atmospheric models.

The seasonal evolution of the continental heat budget for different monsoon systems (Fig. 2) shows that sensible heat flux from the land surface increases during spring and heats up the atmospheric column prior to the rainy season.

By the way, here is a somewhat different view of the issue, which points to a more dominant role for atmospheric rather than oceanic heat transport, courtesy Richard Seagar: http://www.ldeo.columbia.edu/res/div/ocp/gs/

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.

The only trend I see in those 161 years is one that correlates beautifully with all estimates of increasing atmospheric CO2 since 1850 assuming that 45 % of emissions (as per CDIAC datasets) is retained in the atmosphere and, with a delay of around 15 years (possibly due to the ocean heatsink, aka Hansen's «pipeline»), heats the surface by 2.8 - 2.9 C for each doubling of atmospheric CO2.

there IS a need for a NET energy transfer FROM the atmosphere TO the ocean, if we are to accept the climastrologists» explanation for the «missing» atmospheric heat.

For example, the Hadley cell, the large - scale pattern of atmospheric circulation that transports heat from the tropics to the subtropics, has marched south during recent decades, moving the subtropical dry zone (a band that receives little rainfall) along with it.

Part of problem is that even with current levels of emissions, the inertia of the climate system means that not all of the warming those emissions will cause has happened yet — a certain amount is «in the pipeline» and will only rear its head in the future, because the ocean absorbs some of the heat, delaying the inherent atmospheric warming for decades to centuries.

The tropics are a region of heat gain for the globe: Tropical ocean sea surface temperatures influence atmospheric circulation, which redistributes heat and moisture from the tropics around the world.

We have to consider trends in the heat budget of the oceans and what that portends for future atmospheric warming.
