Pan-Atlantic decadal climate oscillation linked to ocean circulation
Communications Earth & Environment, 2023 Atlantic climate displays an oscillatory mode at a period of 10–15 years described as pan-Atlantic decadal oscillation. Prevailing theories on the mode are based on thermodynamic air-sea interactions and the role of ocean circulation remains uncertain ...

Performance analysis of modeling scale on multiband oscillations in grid-connected wind farm
Frontiers in Energy Research, 2023 Grid-connected permanent magnet synchronous generator (PMSG) wind farms may be susceptible to oscillation when connected to weak grids. This paper explores the root causes of the oscillations from two perspectives: the model and the oscillation frequency
