Sentences with phrase «temperature gradient now»

Not exact matches

«We chose the iconic Great Barrier Reef because water temperature varies by 8 - 9 degrees along its full length from summer to winter, and because there are wide local variations in pH. In other words, its natural gradients encompass the sorts of conditions that will apply several decades from now under business - as - usual greenhouse gas emissions.»

Now the matching is just «almost perfect» if there is a temperature gradient, because the photon density must slowly decrease to match the local excitation temperature.

Until now, these changes have been gradual shifts across temperature and moisture gradients, rather than abrupt.

In the worst case, as the temperature gradient between the freezing water and the air increases, the energy transfer from the water to the air may now equal the energy loss from the air, at which point the air will stop getting colder.

TE, if the AMOC stops, their maps show that Atlantic temperature gradient is enhanced over what we have now, because the fresh cold meltwater and sea ice comes much further south and tightens the gradient.

Now, sketch a plot of temperature against altitude, then, pick a point around 4Km altitude and reduce the gradient of the plot by rotating it anticlockwise about that pivoting altitude.

Now, Rob, this is the most ludicrous and unsubstantiated statement in Pierrehumbert's «gold standard» where, on page 100, he clearly assumes (from his incorrect computations) that 10 % water vapour in the atmosphere would raise the temperature from 250K to 350K whilst at the same time reducing the temperature gradient.

Now I can construct a heat engine which extracts useful work based on the temperature gradient and gravity will continue to organize the air column forever and my heat engine will never run out of «fuel»?

It seems that the upwards gradient from 1990 to now that appears in a lot of global surface temperature data (whether correct or not) is being used to drive policy.

But now that the skin has warmed up, the temperature gradient across the subskin begins to decrease, and hence so does upward transport of heat energy via convection / conduction.

Loarie et al. (2009) calculated velocities of climate change in terms of relative changes in temperature gradients using three different emissions scenarios (A2, AB, and B1) and concluded that between 2050 to 2100, organisms now living in areas that cover about 29 percent of the planet's land will have to disperse faster than observed post-glacial velocities.

Even if the wind stayed constant, if the steering level lowered, then systems would move more slowly eastward... I could imagine a lowering of the steering level in response to a decreased surface potential temperature gradient... though now I'm not sure if my reasoning is correct...
