Nonlinear features of equatorial baroclinic Rossby waves detected in Topex altimeter observations
Nonlinear features equatorial baroclinic Rossby waves Topex altimeter observations
2009/11/16
Using a recently proposed technique for statistical analysis of non-gridded satellite altimeter data, regime of long equatorially-trapped baroclinic Rossby waves is studied. One-dimensional spatial an...
Multivariate autoregressive modelling of sea level time series from TOPEX/Poseidon satellite altimetry
Multivariate autoregressive modelling sea level time series TOPEX/Poseidon satellite altimetry
2009/11/9
This work addresses the autoregressive modelling of sea level time series from TOPEX/Poseidon satellite altimetry mission. Datasets from remote sensing applications are typically very large and correl...
用1993~1999年的TOPEX/Poseidon卫星测高资料, 分析了南海海面高度距平场(SSHA)的平均周年变化; 结合历史水文资料, 反演了多年平均的逐月海面动力地形; 探讨了南海动力地形及其所反映的上层环流季节特征和演变规律. 分析表明, 南海大尺度环流的周年演替可分为4个阶段. 冬季(11~2月)南海环流表现为以北部气旋环流为主的气旋型双圈结构, 相关的特征还包括吕宋海峡的黑潮入侵和加...
Variability and Energetics of the Kuroshio Extension and Its Recirculation Gyre from the First Two-Year TOPEX Data
sea surface height eddy kinetic energy
2008/12/12
Altimetry data from the first 21-month TOPEX mission (September 1992–June 1994) are analysed to investigate the sea surface height (SSH) fluctuations in the Kuroshio Extension and its southern recircu...
Annual Variability of the Subtropical Recirculations in the North Atlantic and North Pacific：A Topex/Poseidon Study
Subtropical Recirculations North Atlantic North Pacific Topex/Poseidon Study
2008/12/11
Using sea surface height data collected by Geosat and Topex/Poseidon, the seasonal (annual) gyre circulations in the regions of the Gulf Stream and the Kuroshio Extension were studied. The seasonal gy...
Global Characteristics of Ocean Variability Estimated from Regional TOPEX/POSEIDON Altimeter Measurements
sea surface height Centre National d’Etudes Spatiales
2008/11/26
Three years of altimetric data from the TOPEX/POSEIDON spacecraft have been used to study characteristics of eddy variability over the World Ocean. The nature of the variability and its spatial struct...
Seasonal Eddy Field Modulation of the North Pacific Subtropical Countercurrent: TOPEX/Poseidon Observations and Theory
Seasonal Eddy Field Modulation North Pacific Subtropical Countercurrent TOPEX
2008/7/22
Altimetry data from the first 5¼-yr TOPEX/Poseidon mission (October 1992–December 1997) are analyzed focusing on the North Pacific Subtropical Countercurrent (STCC) near the center of the Pacif...
Coupled Pattern Analysis of Sea Surface Temperature and TOPEX/Poseidon Sea Surface Height
Coupled Pattern Analysis Sea Surface Temperature TOPEX/Poseidon Sea Surface Height
2008/7/10
Though thermal effects dominate steric changes in sea level, the long-period contribution of thermal expansion to sea level is uncertain. Nerem et al. found that a global map of sea surface temperatur...
浅海区域Topex/Poseidon测高卫星数据波形重构方法
卫星测高波形重构 波形数据
2010/12/23
根据测高卫星返回波形的特征，给出了由Topex/Poseidon卫星波形数据进行波形重构的方法,并采用函数逼近算法确定波形重构改正量，进而改善测高卫星近海岸海面高观测值的精度.在中国南海区域计算了四圈T/P测高卫星经过波形重构后的海面高数据.近海岸海面高数据与相近时刻验潮站数据相比，精度比波形重构前有了很大提高，证明该方法的有效性.
