Copula–entropy theory for multivariate stochastic modeling in water engineeringSpringer Science and Business Media LLC - Tập 5 - Trang 1-17 - 2018
Vijay P. Singh, Lan Zhang
The copula–entropy theory combines the entropy theory and the copula theory. The entropy theory has been extensively applied to derive the most probable univariate distribution subject to specified constraints by applying the principle of maximum entropy. With the flexibility to model nonlinear dependence structure, parametric copulas (e.g., Archimedean, extreme value, meta-elliptical, etc.) have ...... hiện toàn bộ
Frozen-in condition for ions and electrons: implication on magnetic flux transport by dipolarizing flux bundlesSpringer Science and Business Media LLC - Tập 5 - Trang 1-7 - 2018
A. T. Y. Lui
The ability of dipolarizing flux bundles (DFBs) in transporting magnetic flux from the mid-tail reconnection site for near-Earth dipolarization is evaluated by two methods: the generalized Ohm’s law and the concept of flux preserving and line preserving. From the generalized Ohm’s law, the breakdown of the frozen-in condition (FIC) for ions is shown to be intimately related to that for electrons. ...... hiện toàn bộ
Evaluating precipitation prediction skill for the pre- and postrainy seasons in South China in ECMWF subseasonal forecastsSpringer Science and Business Media LLC - - 2024
Yanan Liu, Qiong Wu, Yizhi Zhang, Lujun Jiang
The rainy season in South China is divided into two phases, the pre- and postrainy seasons, according to the seasonal progression of the East Asian summer monsoon. The precipitation prediction skills for the two rainy seasons are investigated using subseasonal-to-seasonal (S2S) hindcast data from the European Centre for Medium-Range Weather Forecasts (ECMWF) for 2001–2019. The precipitation predic...... hiện toàn bộ
Relation of land surface temperature with different vegetation indices using multi-temporal remote sensing data in Sahiwal region, PakistanSpringer Science and Business Media LLC - Tập 10 - Trang 1-14 - 2023

At the global and regional scales, green vegetation cover has the ability to affect the climate and land surface fluxes. Climate is an important factor which plays an important role in vegetation cover. This research aimed to study the changes in land cover and relation of different vegetation indices with temperature using multi-temporal satellite data in Sahiwal region, Pakistan. Supervised clas...... hiện toàn bộ
Asymmetry in the Earth’s magnetotail neutral sheet rotation due to IMF $$B_y$$ sign?Springer Science and Business Media LLC - Tập 8 - Trang 1-11 - 2021
Timo Pitkänen, Anita Kullen, Lei Cai, Jong-Sun Park, Heikki Vanhamäki, Maria Hamrin, Anita T. Aikio, G. Siung Chong, Alexandre De Spiegeleer, Quanqi Shi
Evidence suggests that a non-zero dawn–dusk interplanetary magnetic field (IMF
$$B_y$$
) can cause a rotation of the cross-tail current sheet/neutral sheet around its axis aligned with the Sun–Earth line in Earth’s magnetotail. We use Geotail, THEMIS and Cluster data to statistically investigate ho...... hiện toàn bộ
Benefits of radar-derived surface current assimilation for South of Africa ocean circulationSpringer Science and Business Media LLC - Tập 8 - Trang 1-11 - 2021
Xavier Couvelard, Christophe Messager, Pierrick Penven, Sébastien Smet, Philippe Lattes
The oceanic circulation south of Africa is characterised by a complex dynamics with a strong variability due to the presence of the Agulhas current and numerous eddies. This area of interest is also the location of several natural gas fields under seafloor which are targeted for drilling and exploitation. The complex and powerful ocean currents induces significant issues for ship operations at the...... hiện toàn bộ
Evaluation of the seasonal to decadal variability in dynamic sea level simulations from CMIP5 to CMIP6Springer Science and Business Media LLC - Tập 10 - Trang 1-11 - 2023
Chenyang Jin, Hailong Liu, Pengfei Lin
Previous studies have revealed little progress in the ensemble mean of Coupled Model Intercomparison Project Phase 6 (CMIP6) models compared to Phase 5 (CMIP5) models in simulating global dynamic sea level (DSL). This study investigates the performance of the CMIP5 and CMIP6 ensembles in simulating the spatial pattern and magnitude of DSL climatology, seasonal variability, interannual variability,...... hiện toàn bộ
