Sentences with phrase «relatively more warm water»

Relatively more warm water would remain at the equator and in the Southern hemisphere, which might increase the (lagged) temperature response in the Southern hemisphere.

Not exact matches

Driven by stronger winds resulting from climate change, ocean waters in the Southern Ocean are mixing more powerfully, so that relatively warm deep water rises to the surface and eats away at the underside of the ice.

Velicogna and her colleagues also measured a dramatic loss of Greenland ice, as much as 38 cubic miles per year between 2002 and 2005 — even more troubling, given that an influx of fresh melt water into the salty North Atlantic could in theory shut off the system of ocean currents that keep Europe relatively warm.

That deep water is not only rich in nutrients, it also has relatively high concentrations of carbon dioxide, both because it is cold (cold water can absorb and hold more carbon dioxide than warm water) and because the decomposition of organic matter that sinks into the depths releases carbon dioxide.

It is true, however, that most heavy snowfalls occur with relatively warm air temperatures near the ground — typically 15 °F or warmer since air can hold more water vapor at warmer temperatures.»

I have also read in a reputable book that one of the reasons the warm pool is higher is merely due to the fact that warm water occupies more room, ie for hydrostatic equilibrium to apply the relatively deep warm pool should be higher than the cooler water to the East.

Reduced mixing with relatively warmer sub-surface waters effectively reduces the thermal mass exposed to the cold Antarctic air - slightly more ice forms.

The paper discusses that melting ice will decrease the salinity of the ocean waters around Antarctica, which will cause decreased mixing with the relatively warmer deep ocean waters, reducing sea surface temperatures, causing more sea ice to form.

El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fishing

This circumpolar deep water, which is relatively warm and salty compared to other parts of the Southern Ocean, has warmed and shoaled in recent decades, and can melt ice at the base of glaciers which reduces friction and allows them to flow more freely.

Extratropical cyclones are distinct from tropical cyclones, which are generally smaller and more intense, and, as their name implies, originate over relatively warm water in the tropics.

These effects are relatively well understood in the lowest level of the atmosphere, the troposphere, where increased warming leads to greater evaporation, causing more water vapour and so further warming, although this is offset to some extent through the formation of clouds that reflect incoming sunlight back into space.

(i) The observation that the earlier SSTs, expressed as anomalies from recent averages, are not only too cold relative to NMATs similarly expressed (Barnett, 1984), but also, outside the tropics, show enhanced annual cycles, presumably because more heat is lost from uninsulated buckets in winter when stronger, colder winds blow over relatively warm water (Wright, 1986; Bottomley et al., 1990);

Scientists have uncovered more evidence for a dramatic weakening in the vast ocean current that gives Britain its relatively balmy climate by dragging warm water northwards from the tropics.

The science is here is relatively straightforward: As the atmosphere warms, it can hold more water vapor.
