电离层电流产生的磁场是地磁场卫星测绘时需要剔除的干扰源.利用电离层热层模式TIE-GCM计算电离层中的中性风、重力驱动和压强梯度等形成的电离层电流的全球分布，分析电流在特定位置产生的磁场及磁场三分量随纬度的变化规律.结果表明，E层尤其是磁赤道和极区的电流密度较大，可达103nA·m-2量级，F层电流密度量级约为10nA·m-2.在磁静日（Kp≤ 1）夜间22：00LT-04：00LT，电离层电流在...
Scale interactions in the tropical Atlanticvariability simulated with a coupled GCM

2015/9/17
Warm and cold events in the Gulf of Guinea are an important feature in the interannual variability of the tropical Atlantic Ocean, and partly a manifestation of the equatorial Atlantic system's intrin...
Spatial and temporal analysis of the seasonal and interannual variability in the tropical Pacific simulated with a coupled GCM

In the first part of this work, the dominant time scales that explain the tropical variability of the first SINTEX simulation (ECHAM4(T30)-ORCA) are identified through a spectral analysis. Higher orde...
Low-frequency variability in idealised GCM experiments with circumpolar and localised storm tracks
Low-frequency variability idealised GCM experiments circumpolar localised storm tracks
2009/11/12
Idealised global circulation model simulations with circumpolar and localised (one and two) storm tracks are re-analysed to determine scaling, intermittency and phase-space structures. In a hundred ye...
Comparison between Local Ensemble Transform Kalman Filter and PSAS in the NASA finite volume GCM–perfect model experiments
Local Ensemble Transform Kalman Filter PSAS NASA finite volume GCM–perfect model
2009/11/2
This paper compares the performance of the Local Ensemble Transform Kalman Filter (LETKF) with the Physical-Space Statistical Analysis System (PSAS) under a perfect model scenario. PSAS is a 3D-Var as...
