Two-dimensional turbulence above topography: condensation transition and selection of minimum enstrophy solutions

B Gallet - Journal of Fluid Mechanics, 2024 - cambridge.org
We consider two-dimensional flows above topography, revisiting the selective decay (or
minimum enstrophy) hypothesis of Bretherton and Haidvogel. We derive a 'condensed …

Chlorophyll-a interannual and seasonal variability in Panay Gulf: Identification of potential productive sites in the municipal waters and offshore blooms aided by water …

GL Guirhem-Helican, CS Acabado - Regional Studies in Marine Science, 2024 - Elsevier
Abstract Chlorophyll-a (Chl-a) is often used as a substitute for marine primary productivity
measurements in fishing grounds. Panay Gulf stands as one of the Philippines' vital fishing …

Emergent vorticity asymmetry of one and two-layer shallow water system captured by a next-order balanced model

RS Dù, KS Smith - arXiv preprint arXiv:2411.02291, 2024 - arxiv.org
The quasigeostrophic (QG) system has served as a useful simplified model for
understanding geophysical physical fluid phenomena. The fact that it is based on only one …

The Wind-Driven Time-Variable Circulation in the Arctic Mediterranean

ALP Sjur, PE Isachsen, J Nilsson… - Authorea …, 2024 - essopenarchive.org
The Arctic Ocean is a key component of Earth's climate system, and an understanding of
ocean dynamics in this region is central for predicting how the Arctic is responding to a …

An Idealized Numerical Model Study of Bottom Topographic Influence on Momentum Fluxes, with Emphasis on Contrasting Prograde and Retrograde Flow

JE Slørdal - 2024 - duo.uio.no
Given the strong topographic steering of large-scale ocean currents at high latitudes, and
especially in the Artic Ocean, mesoscale eddy fluxes become of major importance as they …
