Abstract

The Regional Ocean Modeling System (ROMS) is integrated across the Arabian Sea (AS) from 1992 to 2021 and covers 33^°E to 80^°E and 5^°N to 32^°N at high horizontal resolutions of 1/4^°(∼25 km). The study demonstrates that the variability is controlled by a seasonal high-resolution setup, with superior performance for various seasons during the months of December-January-February (DJF), March-April-May (MAM), June-July-August-September (JJAS) and October–November (ON). The Sea Surface Temperature (SST) anomalies in the JJAS season werestudied. SST dominates the seasonal variability of the Indian summer monsoon (ISM). Our results show that the ROMS can simulate seasonal variability and its effects on the upper ocean properties over the AS. In addition, the impact of monthly variation is controlled. In recreating the spatio-temporal distribution of surface as well as subsurface hydrographic parameters such as surface and subsurface temperature, the simulation results are reasonable like observation and reanalysis.

探索阿拉伯海的时空 SST 模式及其影响：区域海洋建模系统的启示

区域海洋模拟系统（ROMS）从 1992 年至 2021 年在阿拉伯海（AS）范围内集成，覆盖东经 33 度至 80 度和北纬 5 度至 32 度，水平分辨率高达 1/4 度（25 千米）。研究表明，变率受季节性高分辨率设置的控制，在 12 月-1 月-2 月（DJF）、3 月-4 月-5 月（MAM）、6 月-7 月-8 月-9 月（JJAS）和 10 月-11 月（ON）等不同季节具有卓越的性能。我们研究了 "日本-雅加达 "季节的海面温度（SST）异常。SST 主导着印度夏季季风（ISM）的季节变化。我们的研究结果表明，ROMS 可以模拟季节变化及其对 AS 上层海洋特性的影响。此外，月度变化的影响也得到了控制。在再现表层和次表层水文参数（如表层和次表层温度）的时空分布方面，模拟结果与观测和再分析结果一样合理。

期刊介绍： Continental Shelf Research publishes articles dealing with the biological, chemical, geological and physical oceanography of the shallow marine environment, from coastal and estuarine waters out to the shelf break. The continental shelf is a critical environment within the land-ocean continuum, and many processes, functions and problems in the continental shelf are driven by terrestrial inputs transported through the rivers and estuaries to the coastal and continental shelf areas. Manuscripts that deal with these topics must make a clear link to the continental shelf. Examples of research areas include: Physical sedimentology and geomorphology Geochemistry of the coastal ocean (inorganic and organic) Marine environment and anthropogenic effects Interaction of physical dynamics with natural and manmade shoreline features Benthic, phytoplankton and zooplankton ecology Coastal water and sediment quality, and ecosystem health Benthic-pelagic coupling (physical and biogeochemical) Interactions between physical dynamics (waves, currents, mixing, etc.) and biogeochemical cycles Estuarine, coastal and shelf sea modelling and process studies.
