Sentences with phrase «air temperature changes most»

Not exact matches

AIRFLOW: The way air is circulated through most cabins has not changed since the 1980s: air from the engine's compressors is adjusted for temperature, mixed with recycled and filtered air, and then pumped into the cabin above passengers.

Nitrogen brings several improvements over air, but perhaps most significantly is its ability to remain at a stable pressure even under extreme temperature change.

This is what most of us think of when we talk about «Global Warming»; that it is changes in the air temperature!

Global average surface air temperature is one of the most well - recognized metrics of contemporary climate change — hence the term «global warming».

We further estimate that, in most northern hemispheric regions, these changes in the likelihood of extreme summer mean WBGT are roughly an order of magnitude larger than the corresponding changes in the likelihood of extreme hot summers as simply measured by surface air temperature.

Internal variability can only account for ~ 0.3 °C change in average global surface air temperature at most over periods of several decades, and scientific studies have consistently shown that it can not account for more than a small fraction of the global warming over the past century.

Leaf area index, which is also enhanced by increasing atmospheric carbon dioxide, was the second most important factor, contributing an additional 21.8 percent, followed by climate change (precipitation and air temperature together) and the fraction of photosynthetically active radiation, which accounted for the remaining 18.3 and 14.6 percent increase in NPP, respectively.

The averaged surface air temperature anomaly (dT) is widely recognised to be the most important index characterising the global climate changes including «global warming» (Bell et al. 1998; Anisimov and Polyakov 1999).

A phase change involves no change in temperature so for the condensate to be at the same temperature as the surrounding air then due to its higher thermal capacity it must retain most if not all the latent heat released from the vapour form.

Therefore, I find it hard to see how a * living * upper treeline of very old trees can measure any temperature changes over their age greater than 1.2 C (ok, make it 1.5 C at most with unsaturated air).

One of the most striking changes is the decline of sea ice concurrent with changes in atmospheric circulation and increased surface air temperature.

All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.

The survey shows that most health insurers are not preparing for climate change - related temperature extremes, decreasing air quality, and the increased spread of diseases.

However, for changes over time, only anomalies, as departures from a climatology, are used, most commonly based on the area - weighted global average of the sea surface temperature anomaly and land surface air temperature anomaly.

Warmer Temps Likely to Blame The original paper gives a number of examples which show that changes in land use, precipitation, cloudiness and humidity are superimposed on glaciers similar to those of Kilimanjaro, in terms of latitude, and that something else is at work... «most obvious would be warmer air temperatures».
