High-resolution analysis of the physicochemical characteristics of sandstone media at the lithofacies scale [PDF]
Solid Earth, 2020 The prediction of physicochemical rock properties in subsurface models regularly suffers from uncertainty observed at the submeter scale. Although at this scale – which is commonly termed the lithofacies scale – the physicochemical variability plays a ...

Triple cascade behaviour in QG and drift turbulence and generation of zonal jets [PDF]
, 2009 We study quasigeostrophic (QG) and plasma drift turbulence within the Charney-Hasegawa-Mima (CHM) model. We focus on the zonostrophy, an extra invariant in the CHM model, and on its role in the formation of zonal jets.

Modulational instability of Rossby and drift waves and generation of zonal jets [PDF]
, 2010 We study the modulational instability of geophysical Rossby and plasma drill waves within the Charney-Hasegawa-Mima (CH M) model both theoretically, using truncated (four-mode and three-mode) models, and numerically, using direct simulations of CHM ...

Investigating tensor anisotropy of cosmic rays during large-scale solar wind disturbances
Solar-Terrestrial Physics, 2017 The observable anisotropy of cosmic rays has first been decomposed into zonal harmonics and components of vector and tensor anisotropy. We examine Forbush decreases in cosmic rays that occurred in November 2001 and November 2004.

Statistical characteristics of gravity wave activities observed by an OH airglow imager at Xinglong, in northern China [PDF]
Annales Geophysicae, 2011 An all-sky airglow imager (ASAI) was installed at Xinglong, in northern China (40.2° N, 117.4° E) in November 2009 to study the morphology of atmospheric gravity waves (AGWs) in the mesosphere and lower thermosphere (MLT) region.

Frontiers in Marine Science, 2022 Acoustic rays are modified while propagating through oceanic eddies. However, due to the lack of field synchronous observation, the impact of mesoscale eddy on the acoustic propagation is less clarified. To address the issue, an eddy-acoustic synchronous

Analysis of anisotropic variogram models for prediction of the Curonian lagoon data
Mathematical Modelling and Analysis, 2006 The anisotropy in particular environmental phenomena is detected when behavior of a physical process differs in different directions. In this paper geometric and zonal anisotropies are considered.

Towards Hyper-Dimensional Variography Using the Product-Sum Covariance Model
Atmosphere, 2019 Modeling hyper-dimensional spatial variability is a complex task from both practical and theoretical standpoints. In this paper we develop a method for modeling hyper-dimensional covariance (variogram) structures using the product-sum covariance model ...
