Sentences with phrase «ocean convection over»

For instance, changes in ocean convection over the north Atlantic would affect the jet stream, which would have a dramatic effect upon regional precipitation, probably leading to acute drought in the northern hemisphere, which will weaken and push the northern jet stream toward the Arctic.

Not exact matches

Rapid vertical mixing in the convection areas that exist everywhere over the warm ocean and in which the warm air rises takes care of the rest.

Over the oceans where most tropical moist convection occurs, the amplification in the model is greater — about a factor of 1.4.

The key however is to integrate over the whole space of internal variability — which includes variations in the North Atlantic Ocean convection.

However, over land, where there is not very much moist convection, which is not dominated by the tropics and where one expects surface trends to be greater than for the oceans, there was no amplification at all!

Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold water from the north whenever the Gulf Stream is running quickly.

The mechanism by which the effect of oceanic variability over time is transferred to the atmosphere involves evaporation, conduction, convection, clouds and rainfall the significance of which has to date been almost entirely ignored due to the absence of the necessary data especially as regards the effect of cloudiness changes on global albedo and thus the amount of solar energy able to enter the oceans.

The «unnatural» warming so far seen is however trended strongly to the alterations to the planetary surface by Humanity over the past 400 years and the rebalance towards greater kinetic induction (in its cumulative effect) is now producing observable alterations not only to the Land Surface median Temperature, but to the Ocean (vie conduction / convection) and a still unconfirmed claim of a small overall rise in Median Atmospheric Temperature, which if «true» would place the Planetary Biosphere on the «Human Population Plot» with regard to «warming».

Over ocean stretches with a positive SST anomaly air convection is higher (as the temperature difference between the warm sea surface and the cool air higher up in the troposphere is greater), so a higher likelihood for the formation of depressions exists and more precipitation is to be expected.

The only possible explanation for why the average temperature of the ocean is 4C is because that is the average surface temperature of the earth taken over a period of time long enough for convection and conduction to equilibrate the entire volume.

You have to deal with how the system evolves over time, which means convection both within the atmosphere and the ocean; 5.

The spread of warm waters across the Pacific in collaboration with changing winds in turn promotes evaporative cooling of the ocean, moistening the atmosphere, and fueling tropical storms and convection over and around the anomalously warm waters.
