The Patos Lagoon summertime circulation and dynamics

SWOT Reveals How the 2024 Disastrous Flood in South Brazil Was Intensified by Increased Water Slope and Wind Forcing

“…These findings corroborate previous studies investigating the influence of wind on the Patos‐Guaíba system (Möller et al., 1996, 2001; Monteiro et al., 2011). According to Möller et al.…”

“…These findings corroborate previous studies investigating the influence of wind on the Patos-Guaíba system (Möller et al, 1996(Möller et al, , 2001;;Monteiro et al, 2011). According to Möller et al (2001), the Patos Lagoon is susceptible to changes in flow dynamics due to SW winds during cold front passages, potentially increasing water levels by several centimeters over short time intervals.…”

Dynamics of Water Quality in the Mirim–Patos–Mangueira Coastal Lagoon System with Sentinel-3 OLCI Data

“…The behavior of the Guaíba river plume and the formation of current lines observed in this study align with earlier findings describing its interaction with the submerged barrier [55]. The seaward movement along the right margin, noted on 9 May 2024, reflects patterns previously documented under similar hydrodynamic conditions [56]. Furthermore, the well-formed current lines observed on 2 July 2024 correspond to modeled scenarios of the Patos Lagoon, where low transverse mixing plays a significant role [55,57].…”

A modeling study of Patos lagoon (Brazil) flow response to idealized wind and river discharge: dynamical analysis

“…This is in contrast with the results of Moller et al (1996), which found a geostrophic balance in the cross-shore direction even nearshore. The nonlinear terms are negative over the banks, leading to an additional ageostrophic increase in the cross-shore pressure gradient.…”

“…The result shows that the lagoon flow experiences only small accelerations after day 1.25 and is nearly in steady state after 2 days. After a steady state is reached, the alongshore balance at Arambaré is similar to the result found by Moller et al (1996) for a mid-section. The major balance is between the surface stress and the pressure gradient.…”
