Sensitivity of the global hydrological cycle to the altitude of stratospheric sulphate aerosol layer

Environmental Research Letters
Stratospheric aerosol geoengineering (SAG) has been proposed as one of the potential options to offset the impacts of anthropogenically induced climate change.

Analytical Prediction of Critical Transitions in Oscillator Networks With Non‐Local Links

Advanced Science, EarlyView.
An analytical framework reveals how global coupling, second‐harmonic strength, noise, and network structure govern oscillator‐based Ising dynamics. Spectral reduction predicts stability boundaries, while Fokker–Planck analysis captures one‐ to two‐cluster transitions and identifies conditions favoring low‐energy configurations.

A global science-policy partnership for progress toward sustainability of oceanic ecosystems and fisheries

, 2013
Oceanic ecosystems support livelihoods and supply food for hundreds of millions of people. But these ecosystems are deteriorating rapidly and many of the world's oceanic fisheries are in a precarious condition.

Low Threshold Vertical Cavity Surface Emitting Lasers Based on CsPbI3 Thin Films

Advanced Science, EarlyView.
The first vertical‐cavity surface‐emitting laser (VCSEL) based on CsPbI3 thin films is fabricated by planar hot pressing. By optimizing the cavity design through optical gain assessment and rigorous coupled‐wave analysis, the VCSEL achieved an exceptionally low lasing threshold of 2.8 µJ cm−2.

Ocean science in the NRC

Eos, Transactions American Geophysical Union, 1983
Oceanographers all share an interest in the environment and want to make progress understanding it. To make progress in this and in other aspects of our science we need a steady influx of young scientists, better ways of observing and computing, and new ideas about how things work.

CW‐Pumped Amplified Spontaneous Emission From Thermally Evaporated CsPbBr3 Films

Advanced Science, EarlyView.
Thermally evaporated CsPbBr3 thin films sustain amplified spontaneous emission from short‐pulse toward quasi‐continuous‐wave excitation. Time‐resolved spectroscopy, controlled excitation, and substrate engineering reveal how excitation duration governs optical‐gain stability.

Equatorial convection controls boreal summer intraseasonal oscillations in the present and future climates

npj Climate and Atmospheric Science
The boreal summer intraseasonal oscillation (BSISO) is the major mode of tropical intraseasonal variability during the Indian summer monsoon (ISM), it partly controls the dry and wet spells of the ISM and thus is crucial for agricultural yield in the ...

Improved Skills for Predicting Sub‐Seasonal to Seasonal Global Sea Surface Temperature

Advanced Science, EarlyView.
Addressing the critical Sub‐seasonal to Seasonal predictability gap, this study presents CAS‐Canglong, a novel deep learning framework. By leveraging 3D Swin‐Transformers to capture long‐range ocean interactions, the model demonstrates superior skill over traditional GCMs.
