Wind Wave Effects on the Doppler Spectrum of the Ka-Band Spaceborne Doppler Measurement
Remote SensingSea surface wind, waves, and currents are the three basic parameters that describe the dynamic process of sea surface, and they are coupled with each other. To more accurately describe large-scale ocean motion and extract the ocean dynamic parameters, we

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.

On ocean currents produced by winds
Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935 Abstract The effect of a steady wind blowing over the surface of the open sea is to produce a current which is inclined to the direction of the wind. The resultant drift of the water is perpendicular to the wind, but at the surface the current is at an inclination of 45° to the wind. These results hold when the sea may be treated as a

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.
