The global mean sea level (GMSL) has been measured precisely by the space geodetic remote-sensing technique of radar altimetry since 1990s. Aside from well-studied seasonality and secular rise, here we focus on GMSL variation interannual–decadal (ID) timescales (GMSL-ID) investigate influences climatic oscillations as physical causes. We conduct correlation analyses GMSL-ID time series with sev...
This is an addendum to our preceding article, ‘NMR pD-variation method determine the proper stabilities of organic electrolyte complexes: case histidine complexes with a cyclophane acid’ Supramolecular Chemistry https://doi.org/10.1080/10610278.2022.2134017, which proposes that species distribution between electrolytes determined by observing pD dependence NMR signals for mixture reactants; can...
Abstract Assessing variations in the annual runoff coefficient (RC) on a basin scale is crucial for understanding hydrological cycle under natural and anthropogenic changes, yet systematic global assessment remains unexamined from water-balance perspective. Here, we combine observation-based precipitation datasets to quantify basin-averaged RC changes 433 major river basins during period 1985–2...
The existence of outflow in the advection dominated accretion flows has been confirmed by both numerical simulations and observations. The outow models for ADAF have been investigated by several groups with a simple self similar solution. But this solution is inaccurate at the inner regions and can not explain the emitted spectrum of the flow; so, it is necessary to obtain a global solution for...
The present study classified global Ecosystem Functional Types (EFTs) derived from seasonal vegetation dynamics of the GIMMS3g NDVI time-series. Rotated Principal Component Analysis (PCA) was run on the derived phenological and productivity variables, which selected the Standing Biomass (approximation of Net Primary Productivity), the Cyclic Fraction (seasonal vegetation productivity), the Perm...
