[1] The atmosphere, hydrosphere, and cryosphere form a fully coupled climate system. This system exhibits a number of large‒scale phenomena, such as the El Nino–Southern Oscillation, the Asian Monsoon, the North Atlantic Oscillation, and the Madd

Earth’s rotation rate [i.e., length of day (LOD)], the angular momentum of the core (CAM), and surface air temperature (SAT) all have decadal variability. Previous investigators have found that the LOD fluctuations are largely attributed to core–

Uncertainties in polar motion and length-of-day measurements are evaluated empirically using several data series from the space-geodetic techniques of the global positioning system (GPS), satellite laser ranging (SLR), and very long baseline interfer

Short-term forecast of the polar motion is considered by introducing a prediction model for the excitation function that drives the polar motion dynamics. The excitation function model consists of a slowly varying trend, periodic modes with annual an

Atmospheric motions in the retrograde diurnal (S1) band are of interest to a wide community of researchers in earth dynamics and geodesy, due to their potential contribution to the low-frequency motions of the rotation axis known as nutations. Previo

International audience; At the interannual to decadal timescale, the changes in the Earth rotation rate are linked with the El-Nin˜o Southern Oscillation phenomena through changes in the Atmospheric Angular Momentum. As climatic studies demonstrate

The three-dimensional diurnal atmospheric angular momentum (AAM) budget is investigated, and its geographical features and meteorological dynamics are explored. It is shown that the diurnal atmospheric torques are associated with mass effect (ellipso

The relationship of intraseasonal variability to ENSO is investigated using daily length-of-day (LOD), atmospheric angular momentum (AAM), west equatorial Pacific (WPAC) wind stress and monthly Nino3 SST data for the years 1976-1999. Strong coherence

The axial component of atmospheric angular momentum (AAM) reached a decadal minimum during the winter of 1989, when the cool (La Nina) phase of the ENSO cycle and the positive phases of the North Atlantic Oscillation (NAO) and the related Arctic Osci
