Embodiment Construction

[0010] The present invention will be described in detail below in combination with specific embodiments.

[0011] (1) Basic data

[0012] 1) Argo data: The Argo data used is the Argo profile data provided by the website of the Coriolis Global Data Acquisition Center of France. All Argo data has undergone automatic quality control and analysis in the Argo data center, and is widely used; figure 1 For global distribution of Argo buoys.

[0013] 2) Climate-state temperature-salt field data: In order to obtain the temperature-salinity and velocity structure of the synthetic vortex, subtract the climate-state temperature-salt data profile from the Argo temperature-salt profile data inside the vortex to obtain the potential temperature anomaly and salinity anomaly in the vortex And power height abnormalities. The climate-state temperature-salt field data used is the Atlas of Regional Seas 2009 (CARS09) provided by the Australian Commonwealth Scientific and Industrial Research Org...

Abstract

The invention aims to provide a synthesis method of vortex three-dimensional information, and the technical scheme adopted by the invention is as follows: basic data preparation is carried out, wherein the basic data comprises Argo data, climate state temperature salt field data, climate state data and data required by calculation of geostrophic flow and ocean current vertical velocity shearing; and vortex synthesis is carried out. In order to reveal the horizontal and vertical structure of the vortex, a vortex signal detected from satellite altimeter data needs to be combined with Argo temperature and salt data.

Description

technical field [0001] The invention belongs to the technical field of marine information and relates to a method for synthesizing vortex three-dimensional information. Background technique [0002] At present, most studies on mesoscale eddies focus on the characteristics of eddies (e.g. Wang Guihua, 2004; Lin Pengfei, 2005; Chen Gengxin, 2012; Yang Guang, 2013) and their spatial and temporal changes (e.g. Wang et al., 2003; Wu and Chiang, 2007), the generation and evolution of eddies (e.g.D.Wang et al., 2008; G.Wang et al., 2008; Zhuang et al., 2010) and the relationship between mesoscale eddies and Kuroshio (Jia and Liu, 2004 ) and other aspects, most studies on the influence of vortex motion on phytoplankton changes rely on satellite sea surface height data to extract surface current information (e.g. Chelton et al, 2011; F. Liu et al, 2013), because satellites cannot provide Any information on the subsurface depth of the vortex (Qiu and Chen, 2010), therefore, this proj...
