    Ring interaction with the Gulf Stream causes marked changes in shape, size, orientation and location of the ring. A longer history of D is determined by using National Oceanic and Atmospheric Administration Gulf Stream by: Gulf Stream Introduction. The Gulf Stream is a strong, fast-running, and clockwise-rotating system of warm ocean currents that begins in the Gulf of Mexico; proceeds through the Straits of Florida; follows the eastern coast of the United States and the Grand Banks of Newfoundland, Canada, in a general northeasterly direction; and then crosses easterly the North Atlantic Ocean.

    The warm Gulf Stream originating in the tropical Caribbean, for instance, carries about times more water than the Amazon River. The current moves along the U.S. East Coast across the Atlantic Ocean towards Europe. The heat from the Gulf Stream keeps much of Northern Europe significantly warmer than other places equally as far north. Several processes have been identified but the most energetic one is the Gulf Stream Warm Core Ring (WCR, hereafter) interactions with the shelf/slope waters. For example, Joyce et al.

These western boundary current extensions (WBCEs) include the Kuroshio Extension in the North Pacific, the Gulf Stream in the North Atlantic, the Agulhas Return Current in the South Indian Ocean, the East Australian.

Gulf Stream rings are a special type of eddy whose origin has been well documented; they form from cut-off Gulf Stream meanders (Fuglister ). Rings are the most energetic eddies in the ocean and their thermocline displacements, swirl speeds and volume transports are nearly equivalent to those of the Gulf by:   Exploring the impact of Gulf Stream temperature biases on the global atmospheric circulation a focus on reducing the origins of the ocean and SST biases in these regions of high ocean–atmosphere interaction may also reduce some of the global atmospheric biases in coupled global climate models, serving to highlight and direct future.

The swift current speeds in the Gulf Stream in combination with its energetic meanders, rings, and other eddies result in very large temporal current fluctuations and very high levels of eddy kinetic energy (EKE) that coincide with the Gulf Stream between 55°W and 65°W (Figure 7A).

Evidence of recurring rings at or near this location and hence, meanders of the eastern Gulf Stream wall, was found in hydrographic data collected by NOAA over a month period from to These data suggested that two such events, lasting about 4 weeks each, occurred during this period.

The Kuroshio and Gulf Stream, the subtropical western boundary currents of the North Pacific and North Atlantic, play important roles in meridional heat transport and ocean–atmosphere interaction processes.

Using a multimodel ensemble of future projections, we show that a warmer climate intensifies the upper-layer Kuroshio, in contrast to the previously documented slowdown of the Gulf Author: Changlin Chen, Guihua Wang, Shang-Ping Xie, Wei Liu.

A ring is a type of mesoscale eddy that forms when Gulf Stream meanders break off the Stream creating independent circulatory systems. The formation of a Gulf Stream ring is the only way that warm tropical water located south of the Gulf Stream can be moved north of the Gulf Stream. Kwon, Y.-O.

23, – ()Cited by: The atmospheric response to the Gulf Stream front in sea surface temperature is investigated using high-resolution data from satellite observations and operational analysis and forecast.

Two types of atmospheric response are observed with different seasonality and spatial distribution. Like transport, the meandering of the Gulf Stream intensifies downstream of Cape Hatteras, reaching a maximum near 65°W. Meanders often pinch off from the current to form Gulf Stream rings.

On average, the Stream sheds 22 warm-core rings and 35 cold-core rings per year (Hogg and Johns ). Warm core rings are always located between the Gulf Stream and the continental slope.

The life cycle of a warm core ring is generally a few months to a year. These rings usually are reabsorbed by the Gulf Stream, although they also can break apart if they move onto the continental shelf. Warm core rings travel to the west, so many warm core.

Although warm-core rings can slowly change over periods of months through interactions with the surrounding Slope Water, Gulf Stream meanders, continental slope, other rings, and the atmosphere, we have now discovered that major alterations to ring structure can occur during very short periods (2–5 days) when an interaction with the Gulf Cited by: Gulf Stream slowing down is bad news for Ireland Atlantic so the Gulf Stream’s gift of more temperate waters matters hugely to our climate, as does their interaction with the atmosphere to.

In their study, the relationship between satellite-derived 10 m equivalent wind, U 10 N, and T sea − T air (where T sea denotes SST and T air is the near-surface air temperature) in the vicinity of Gulf Stream rings was examined, using the sea surface temperature differences between water in the ring and water that surrounds it as a proxy for T sea − T air.

Gulf Stream rings have either warm or cold cores. The warm-core rings are typically to km (62 to miles) in diameter and have a clockwise rotation. They consist of waters from the Gulf Stream and Sargasso Sea and form when the meanders in the Gulf Stream pinch off on its continental slope side.The Gulf Stream The primary surface current along the east coast of the United States is the Gulf Stream, which was first mapped by Benjamin Franklin in the 18th century (Figure ).As a strong, fast current, it reduced the sailing time for ships traveling from the United States back to Europe, so sailors would use thermometers to locate its warm water and stay within the current.Although warm-core rings can slowly change over periods of months through interactions with the surrounding Slope Water, Gulf Stream meanders, continental slope, other rings, and the atmosphere, we have now discovered that major alterations to ring structure can occur during very short periods ( days) when an interaction with the Gulf Stream Cited by:
