The strong shifts that occurred almost simultaneously in all regions in 1987-1989 may be associated with a major abrupt change in the geostrophic air flow direction over the southern Baltic Sea in 1988 (Soomere and Raamet, 2014) when the average air flow vector turned clockwise by more than 30[degrees].
Absolute vorticity advection by geostrophic wind in 500 hpa level and 1000/500 thickness advection by geostrophic wind of 1000 hpa level can interpret development or decline of the system pressure.
Holomorphic structures in hydrodynamical models of nearly geostrophic flow.
The trigger for reinvigorating the surface winds is unclear, though gravity waves from geostrophic adjustment or distant convection may play a role.
However, transport of larvae off Georges Bank can occur due to unusually strong geostrophic currents, such as in the spring of 1987, with sufficient magnitude to be an important factor influencing the stock composition of neighboring southwesterly regions, such as Nantucket Shoals (Polacheck et al.
Indirect estimates use a relation between horizontal pressure variations and horizontal currents (called the geostrophic relation).
These calculations were forced by 6 x 6 nautical miles (nm) or even coarser gridded geostrophic model winds (from the Swedish Meteorological and Hydrological Institute), by HIRLAM (stands for High Resolution Limited Area Model) or MESAN (Operational Mesoscale Analysis System) winds.
The SCB generally had greater zooplankton than Mexican waters but less appropriate (lower) geostrophic flows.
The time series of the significant wave height and peak period were extracted from the long-term simulations of wave fields for 1970-2007 with a temporal resolution of 1 h for the entire Baltic Sea using the third-generation spectral wave model WAM [40] driven by properly adjusted geostrophic winds.
The wind forcing at a 10 m level was derived from geostrophic winds as recommended by Bumke and Hasse (1989): the geostrophic wind speed was multiplied by 0.
g] the components of the geostrophic velocity (Pond & Pickard 2003).
Dynamical analyses suggest that the geostrophic relation is applicable over a majority of the Indonesian Seas area and that the bottom topography is important in controlling the circulation.
