At this time, anticyclonic
and cyclonic eddies are almost all masked by the strong currents.
The temporal average of the geostrophic currents indicates a predominantly anticyclonic
An upper-air anticyclonic
core, linked to the surface core close to 400S, ensures dry conditions to prevail for the weekend and into the new week.
The arrival of the STB Remnant apparently impelled the AWO into contact with oval BA, leading to the rapid merger of the two anticyclonic
A strengthened Beaufort Gyre is associated with the anticyclonic
circulation regime, or low-index NAM phase (Fig.
In contrast, Blaja and Sturges (1981) presented evidence for a wind-driven circulation in the GM, and anticyclonic
gyre caused predominantly by wind stress curl.
The thermocline was deepest to the west of the study area and an anoxic layer was found at 100 m, interrupted by two anticyclonic
coastal gyres detected through measurements of temperature and salinity.
Lagrangian observations of the anticyclonic
ring in the western Gulf of Mexico.
The schematic above indicates that the mean deep western boundary current continues to flow to the north, but now the mean interior circulation is anticyclonic
(counterclockwise), opposite to that found in the absence of time-dependent motions.
Two ENSO-related processes were proposed to explain this phenomena: 1) the persistent western North Pacific anticyclonic
anomaly in the lower troposphere due to the ENSO-related wind-evaporation-SST feedback (Wang et al.
Satellite Chl-a and geostrophic currents derived from satellite altimetry are used to evaluate the spatial and temporal trajectory of anticyclonic
eddies generated in the CTZ, their interaction with the Juan Fernandez Archipelago, and the potential effect on Chl-a concentrations.
Occasional showers spread also to the south as the upper level vortex formed advecting a band of moist air into its circulation, providing energy which helped trigger its departure: A trite unusual for the time of year, but with some support from the equally valuable and active anticyclonic
cores proceeding along their more southerly tracks between some 38 and 45oS.
high-pressure system towers 8 km over the surrounding cloud tops (nearly as high as Mount Everest).
A comprehensive account of the anticyclonic
ovals of the NNTZ is in press in the Journal, with Gianluigi Adamoli, revealing that a Little Red Spot in this zone has existed for at least 16 years, and revealing correlations for all these ovals between their longevity, size, appearance, and dynamical properties.
Using an ocean model run with atmospheric forcing over the last 50 years, Proshutinsky and Johnson (1997) report two decadally varying regimes corresponding to anticyclonic
and cyclonic circulations of the arctic atmosphere and ocean.
