Atmosphere-Ocean Processes Governing Inflow to the Northern Caribbean Sea

چکیده
Near-surface currents entering the northern Caribbean from Atlantic are described using ocean reanalysis at monthly to daily timescales, underpinned by satellite data assimilation. Statistical analyses involved spatial clustering into current vector modes with associated time scores for quantifying spectral power and regression onto atmospheric fields. Inflow across Anegada, Mona, Windward (AMW) Passages peaks ~100 m depth ~0.2 m/s during summer pulses periods of 45, 100, 365 days, 3, 6.5 years. The intra-seasonal may relate Madden–Julian Oscillations westward Rossby waves, while inter-annual associate regional climate anomalies. An empirical orthogonal function analysis demonstrates that AMW inflow varies multiple timescales is enhanced when subtropical high-pressure ridge penetrates western Caribbean. A case study reveals key features a surge Marine change involves heat advected poleward along edge tropical Atlantic, fed through Sea. Consequently, inflows garners wide interest.

متن کاملData Mining in the Analysis of Ocean-Atmosphere Dynamics in Colombia's Central Caribbean Ocean
This document presents a proposal for the development of an oceanatmosphere dynamic predictive model for the central Caribbean region of Colombia. The proposal is based on temporary data mining techniques and includes the development of a software tool that complements the model. The software tool uses Weka API to implement several algorithms, such as data mining association rules, decision tre...
متن کاملOcean–Atmosphere Covariability in the Western Arabian Sea*
The western Arabian Sea exhibits strong spatial variability in sea surface temperature (SST) during the southwest monsoon, with changes in SST that can exceed 58C over 200 km. Exploration of satellite-based and in situ data shows a strong connection between mesoscale SST features and changes in the atmospheric boundary layer. The fundamental relationship is that of weak (strong) wind velocities...
