1,800 Years of Global Ocean Cooling Halted by Global Warming
1,800 Years Global Ocean Cooling Halted Global Warming
2015/9/9
Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth’s oceans had undergone 1,800 years of a steady cooling trend, according to a new study. Dur...
Winter Circulation in the Western Gulf of Maine：Part 1. Cooling and Water Mass Formation
Winter Circulation Western Gulf Water Mass Formation
2009/2/23
The mean circulation on the northeast continental shelf in the region of the Gulf of Mexico is discussed in terms of a simple box model, based on volume transports and mean salinities estimated from e...
The Response of Intense Oceanic Current Systems Entering Regions of Strong Cooling
Intense Oceanic Current Systems Strong Cooling
2009/1/16
The three-dimensional response of strong currents to cross-stream gradients of surface cooling is studied using numerical simulations. In particular, surface cooling is explored as a possible mechanis...
Response of an Intense Oceanic Current System to Cross-Stream Cooling Events
Intense Oceanic Current System Cross-Stream Cooling Events
2009/1/15
Shifts in location and strength of an intense oceanic flow such as the Gulf Stream to a cross-stream gradient in cooling are studied using two-dimensional numerical simulations. The gradient in coolin...
Circulation Driven by Winds and Surface Cooling
Surface Cooling vertical velocity Circulation Driven
2009/1/6
A three-layer model of ocean circulation in a Northern Hemisphere basin is driven by winds that are anticyclonic in the south and cyclonic in the north. The ocean is also driven by surface cooling, wh...
The effect of cooling on the separated boundary current predicted by the model of Parsons is studied. The separating current is found to strengthen and to move southwards and eastwards. The model is a...
Does Atmospheric Cooling Drive the Gulf Stream Recirculation?
Atmospheric Cooling Gulf Stream Recirculation
2008/12/27
A two-layer model for the recirculation is studied Initially, a narrow jet of the upper layer moves eastward with the lower layer remaining stagnant. Att = 0 cold air flows over the narrow front regio...
A Laboratory Model of Cooling over the Continental Shelf
Laboratory Model Continental Shelf Cooling rate hot water
2008/12/19
A laboratory experiment is conducted where hot water is cooled by exposure to air in a cylindrical rotating tank with a flat shallow outer “continental shelf” region next to a sloping “continental slo...
Is Langmuir Circulation Driven by Surface Waves or Surface Cooling?

Deep-water renewalLake Issyk-Kul driven
2014/5/21
During two field campaigns on Lake Issyk-Kul in March and August 2001, 179 high-resolution conductivitytemperature-depth profiles were measured, along with profiles of dissolved oxyg...
Stratification produced by surface cooling in lakes with significant shallow regions
Stratification produced surface cooling in lakes significant shallow regions
2014/6/10
A reservoir with distinct shallow and deep regions can produce stratification in response to uniform surface heat loss. The shallow region cools more rapidly, and a cold dense gravity current forms th...
