Both currents redistribute mass and heat along the stream current system along Madagascar's coast. [1] The North Madagascar Current flows into the South Equatorial Current just north of Madagascar and is directed into the Mozambique Channel, this connects to the gyre's equatorial currents into the Agulhas Current off the coast of Southeastern ...
Observed vertical velocities of eddy pumping are in the order of one meter per day. However, there are regional differences. In regions where kinetic energy is higher, such as in the Western boundary current, eddies are found to generate stronger vertical currents than eddies in open ocean. [7]
A baroclinic instability is a fluid dynamical instability of fundamental importance in the atmosphere and ocean. It can lead to the formation of transient mesoscale eddies, with a horizontal scale of 10-100 km. [1] [2] In contrast, flows on the largest scale in the ocean are described as ocean currents, the largest scale eddies are mostly created by shearing of two ocean currents and static ...
This gyre is characterized by a clockwise rotation of surface waters, driven by the combined influence of wind, the Earth's rotation, and the shape of the seafloor. The gyre plays a crucial role in the transport of heat, nutrients, and marine life in the Southern Ocean, affecting the distribution of sea ice and influencing regional climate ...
A northern-hemisphere gyre in geostrophic balance. Paler water is less dense than dark water, but more dense than air; the outwards pressure gradient is balanced by the 90 degrees-right-of-flow coriolis force. The structure will eventually dissipate due to friction and mixing of water properties.
Eddies normally travel around one mile per day in these areas; the smoke rings covered five to 10 miles per day and lasted for about six months before splitting up.
The Great Whirl is a huge anti-cyclonic eddy generated by the Somali current flowing in (northern) summer, and one of the two gigantic Indian Ocean Gyres (the other is the Socotra Gyre). The Great Whirl can be observed between 5-10°N and 52-57°E off the Somali coast in the summer season, a location typically around 200 km southwest of the ...
Western boundary currents like the Agulhas, Brazil, and East Australian Currents are known for shedding eddies downward off from their ending points. [6] A semi-permanent cold-core eddy is periodically formed by the Loop Current in the eastern Gulf of Mexico, where warm water from the South Equatorial Current travels upwards through the south ...
