    Skillful prediction of Indian Ocean Dipole index using machine learning models by J.V. Ratnam, Swadhin K. Behera, Masami Nonaka, Kalpesh R. Patil

    Published 2025-02-01
    “…In this study, we evaluated six machine learning models for their skill in predicting the Indian Ocean Dipole (IOD). The results based on the IOD index predictions at 1–8 month lead time indicate that the AdaBoost model with Multi-Layer Perceptron as the base estimator, AdaBoost(MLP), to perform better than the other five models in predicting the IOD index at all lead times. …”

    The Unexpected Oceanic Peak in Energy Input to the Atmosphere and Its Consequences for Monsoon Rainfall by Nandini Ramesh, William R. Boos

    Published 2022-06-01
    “…Observed radiative fluxes suggest that cloud‐radiative effects (CRE) almost double the NEI over ocean, shifting the NEI peak from land to ocean. …”

    Ocean submesoscale fronts induce diabatic heating and convective precipitation within storms by Félix Vivant, Lia Siegelman, Patrice Klein, Hector S. Torres, Dimitris Menemenlis, Andrea M. Molod

    Published 2025-01-01
    “…Abstract The intensity of atmospheric storms is influenced by ocean temperature contrasts. While mesoscale sea surface temperature anomalies ( ~ 200 km-size) are known to intensify storms via latent heat release, the role of finer oceanic scales remains unknown. …”

    A transmission technology of environmental monitoring for ocean based on over-the-horizon skywave by Guojun LI, Xiaofei XU, Changrong YE, Deping ZHANG, Lu TAN, Yakun XING

    Published 2018-09-01
    “…In view of the serious limitation of local resource supply for remote island and reef and the lack of low cost,high reliability long-distance transmission methods for environmental monitoring,relying on the mobile communication base stations widely distributed on the land,an over-the-horizon(OTH) skywave access network based on wide-area cooperative reception was proposed.The problems of channel fading,link asymmetry and spectrum congestion faced by remote island and reef environments monitoring for an OTH skywave transmission were solved from three aspects:physical layer,network layer and perceptive layer.The simulation results of the lower link transmission waveform and the multi-channel fusion algorithm in the typical skywave channel environment show that the reliable access of low-power transceiver in the remote island and reef within a range of 3 000 km could be guaranteed only through the cooperative reception of three access nodes.There was also some reference to monitoring of national ocean-going ships and border defence traffic pass monitoring.…”

    Caustic consideration of long planetary wave packet analysis in the continuously stratified ocean by Arthur D. Gorman, Huijun Yang

    Published 2001-01-01
    “…The wave packet method, one form of the WKB technique, recently has been employed to investigate the evolution of long planetary wave packets in relation to the complex climate variability in the world oceans. However, such a method becomes invalid near the caustics. …”

    Enough Sulfur and Iron for Potential Life Make Enceladus’s Ocean Fully Habitable by Weiming Xu, Can Liu, Ao Zhang, Maggie Lau, H. James Cleaves, Fang Huang, Christopher R. Glein, Jihua Hao

    Published 2025-01-01
    “…The Cassini spacecraft revealed life-forming elements like CHNOP and diverse organic compounds from Enceladus’s ocean. However, the availability of minor but bio-essential nutrients such as iron and sulfur remains unknown. …”
