Sentences with phrase «where high water temperatures»

Professor Don Levitan, chair of the Department of Biological Science, writes in the latest issue of Marine Ecology Progress Series that bleaching — a process where high water temperatures or UV light stresses the coral to the point where it loses its symbiotic algal partner that provides the coral with color — is also affecting the long - term fertility of the coral.

Not exact matches

Gas hydrates naturally form along the coasts of continents and in Arctic permafrost, places where water and gas mix at relatively high pressure and low temperature.

«It's right in the middle of the habitable zone [the region around a star where temperatures are neither too high or too low for liquid water to exist], and it orbits a star very similar to our sun.»

Scientists also study water under more extreme conditions, including at high pressures, where it can exist in the solid state even at room temperature.

Our metric also revealed similar impacts across Eastern Canada in 2010, where high temperatures and significant water deficits led to large wildfires (Fig. 4, 2010) 52.

Possible increased growth and productivity concurrent with climate oscillations that increase water availability, particularly at higher elevations and where stand density is low; extreme high temperatures would have net negative impact, regardless of water availability

Greater numbers of plant species in ruderal based environments were found in equatorial areas where the level of water (represented by mean annual precipitation) related variables are high, whereas competitive and stress tolerant based plant environments were found in locations where energy (represented by mean annual temperature) are expressed with greater weight acting on the distribution.

Water temperatures also vary greatly from a cool chilly May and June where water can dip to the high 50's (15 c) to a warm and tropical mid 80's (30 c) from September to NoveWater temperatures also vary greatly from a cool chilly May and June where water can dip to the high 50's (15 c) to a warm and tropical mid 80's (30 c) from September to Novewater can dip to the high 50's (15 c) to a warm and tropical mid 80's (30 c) from September to November.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Is it not also therefore true that the polar areas of least water vapor, where a greater temperature increase from doubling of Co-2 would have the most effect, has the least W / sq - m percentage of both incoming S - W and outgoing L - W radiation due to the incident angle of incoming Sun light, the high reflectivity of the snow and ice, and the greatly reduced outgoing L - W radiation due to this?

Is it not also therefore true that the polar areas of least water vapor, where a greater temperature increase from doubling of Co-2 would have the most effect, has the least percentage of both incoming S - W and outgoing L - W radiation due to the incident angle of incoming Sun light, the high reflectivity of the snow and ice, and the greatly reduced outgoing L - W radiation due to this?

4) By interpreting the analyss of Bob Tisdale, the global sea surface temperatures used by Endersbee in his calculations have been controlled by warming of the sea surface waters outside the tropical sea surface i.e. mainly by the warming of the sea surface waters of higher latitudes where the sea surface CO2 sinks are.

Even in areas where precipitation does not decrease, these increases in surface evaporation and loss of water from plants lead to more rapid drying of soils if the effects of higher temperatures are not offset by other changes (such as reduced wind speed or increased humidity).5 As soil dries out, a larger proportion of the incoming heat from the sun goes into heating the soil and adjacent air rather than evaporating its moisture, resulting in hotter summers under drier climatic conditions.6

My value of 0.75 (giving a surface temperature of 299K where albedo and atmospheric absorption are zero) may even be too high for a rocky dry planet without water, vegetation or greenhouse gases.

Despite higher than normal surface temperatures and heat contents of ocean waters where the storms developed, evidence is lacking that global warming is revving them up.

While Earth's lower atmosphere is about one percent water vapor (although it seems much higher in the humid Louisiana summers), the upper atmosphere, where ultraviolet radiation can penetrate, is very dry: a cold trap, a combination of pressure and temperature, prevents water vapor from rising high in the earth's atmosphere.

Global surface temperatures were the 8th or 9th highest recorded, partly because the first two months were cool - ish thanks to a La Nina in the Pacific, where cooler waters sit on the top of the ocean and suck up heat from the atmosphere.

In the interest of full disclosure, my «sense» is that such a small temperature increase would not increase water vapor significantly enough to cause a statistically significant increase in numbers and / or severity of extreme events, especially since most of the warming has reportedly been in the high northern latitudes where temperatures are well below 0C where the water vapor saturation value vs temperature curve is pretty flat.

It is exactly what has been happening with surprising frequency since that famous 2003 drought, where the French electricity company had to stop a whole series of nuclear plants because there was not enough water in French rivers, and its temperature was too high.

It means that the global sea surface temperatures used by Endersbee in his calculations have been controlled by warming of the sea surface waters outside the tropical sea surface i.e. mainly the warming of the sea surface waters of higher latitudes where the sea surface CO2 sinks are.

Areas with the most greenhouse gases (tropics) have maximum temperatures that are no where near as high as some desert areas with the lowest amount of GHEs (yeah, yeah, it's the water evaporation and clouds; but that is precisely the point on Earth).

The temperature is never as high at the seaside as it is inland where there is no large body of water.

especially over coral reefs and in shallow estuaries, where high natural surfactant concentrations and subsequent hydrosols persistence may make it economically feasible to lower peak water temperatures for extended periods»

This smaller decline is driven mainly by patterns in arid regions (e.g., northern Africa, Australia, and the Middle East), where losses in suitable plant growing days due to higher temperatures are reduced because those locations are already limited by water availability (compare yellow - and white - colored areas in Fig 2A and 2D).

This instability occurs because the melting point temperature of water decreases as you go deeper in the ocean, where pressures are higher.

Getting electricity out of low temperature water is not easy, but can be done; we have shown the Green Machine, based on the organic Rankine cycle, where a high molecular mass organic fluid is vaporized, runs a turbine and then condensed in a closed loop, creating no emissions.

The situation is different in the tropics where higher temperatures result in higher rates of evapotranspiration, the process by which forests release water into the atmosphere.
