Covariance of the intertropical discontinuity and African easterly jet in Sahelian wet and dry years

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Intertropical discontinuity and African easterly jet (AEJ) positions are strongly correlated, with a more pronounced linear relationship across wet years. Surface heat flux anomalies modify low‐level temperature and sensible heat flux gradients that shift the AEJ core south of the gradient maxima in both composites.

Dual‐Stage Heat Treatment for Enhanced Hydrogen Storage Properties of Mg−Ni−Y Alloys

Rare Metals, EarlyView.
ABSTRACT Mg−Ni−Y alloy is considered to be one of the most promising hydrogen storage materials, but its high dehydrogenation energy barrier hinders its practical application. A dual‐stage heat treatment (490°C × 4 h + 550°C × 4 h) is applied to optimize the microstructure and hydrogen storage performance of a vacuum‐melted Mg94Ni3Y3 alloy.

Research advances in the data assimilative modeling of the Earth's radiation belt electrons

地球与行星物理论评
The Earth's radiation belts are regions where high-energy charged particles congregate in near-Earth space. Given that high-energy particles in the radiation belts pose a severe threat to the safety of spacecraft in orbit and astronauts, it is of vital ...

Forecasting the Radiation Belts in Europe [PDF]

Space Weather, 2012
Weather forecasting has expanded to space weather. As of 1 March 2012, satellite operators and the general public will be able to obtain forecasts of the Earth’s radiation belts, thanks to the SPACECAST project. The opening of the first European system to forecast Earth’s radiation belts, part of the SPACECAST project, is funded by the European Union ...

From Global Mapping to Local Action: Green Finance, Regulatory Frameworks, and Policy Transformation for Sustainable Energy Transition in Qatar and Türkiye

Sustainable Development, EarlyView.
ABSTRACT In 2024, global annual issuance exceeded USD 1.1 trillion mostly through green bonds, credits, and sustainability‐linked instruments, yet significant regional disparities remain. This article examines how Qatar and Türkiye, two hydrocarbon‐dependent but rapidly transitioning economies, are integrating green finance into their sustainability ...
