In this study, CO is used as a tracer to evaluate the chemical field related Asian summer monsoon anticyclone (ASMA) in upper troposphere and lower stratosphere (UTLS) region simulated by Coupled Model Intercomparison Project Phase 6 (CMIP6) climate models from multi-spatiotemporal perspective. The results show that simulations of six selected CMIP6 global are well correlated with MLS observati...

In the persesnt work an artificial satellite theory is developed including all the zonal harmonics of the geopotential besides the post-Newtnian effects arising from the Schwarzschild solution and the Earth's oblateness. The Hamiltonian is formed in terms of the Deluanay canonical variables allowing for the coupling between the Newtonian and the post-Newtonian terms. Small quantities are retain...

The remove-compute-restore (RCR) technique for regional geoid determination implies that both topography and low-degree global geopotential model signals are removed before computation and restored after Stokes' integration or Least Squares Collocation (LSC) solution. The Least Squares Modification of Stokes' Formula (LSMS) technique not requiring gravity reductions is implemented here with a R...

The leading modes of variability of the extratropical circulation in both hemispheres are characterized by deep, zonally symmetric or ‘‘annular’’ structures, with geopotential height perturbations of opposing signs in the polar cap region and in the surrounding zonal ring centered near 458 latitude. The structure and dynamics of the Southern Hemisphere (SH) annular mode have been extensively do...

In this paper potential vorticity (PV) and potential vorticity inversion (PVI) and their application in the cyclogenesis and mesoscale meteorological phenomena are reviewed. PV has been served as a powerful and useful dynamic tracer for the understanding of the large-scale dynamics and synoptic variations in the atmosphere and oceans. Significant progress has been made on the application of PV ...

We investigate forward models of the gravitational potential spectrum generated by ensembles of discrete sources of anomalous mass, having radial distributions with different statistical properties. Models with a random distribution of point source locations throughout the volume of the mantle produce spectra similar to that of the Earth only when the (absolute) source magnitudes increase stron...

Satellite altimetry has become an operational remote sensing technique with important applications to geodynamics. In the present paper, ocean floor topography and tectonic detection in the deep earth are investigated using gravity anomalies from global gravity models and satellite altimetry corrected for waveform distortions. We compute the spherical harmonic degree components of the gravity a...

Causal discovery is the process of identifying cause-and-effect hypotheses from observational data. We use causal discovery to construct networks that track interactions around the globe based on time series data of atmospheric fields, such as daily geopotential height data. At last year’s workshop we explained the basic concepts of using this approach to identify climate properties. Here we re...
