Ensemble reliability and the signal‐to‐noise paradox in ECMWF subseasonal forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We derive a general expression for the ratio of predictable components (RPC) in terms of correlation, spread–error ratio, and total variance ratio. Physical constraints on the admissible solutions (i.e., real‐valued and non‐negative variances) provide a mechanism to identify statistically paradoxical sample combinations of reliability and correlation ...

Dynamics and thermodynamics of the fast and slow Madden–Julian Oscillation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The results of this study highlight the MJO as a complex phenomenon, the behavior of which is driven by an interplay of thermodynamic and dynamic processes. The MJO's distinct speeds are controlled by different mechanisms: slow MJOs propagate eastward primarily via horizontal moisture advection, fast MJOs by vertical moisture advection.

Subseasonal forecasts of the MJO and convectively coupled equatorial waves in ACCESS‐S2 and GraphCast: A multi‐year analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ACCESS‐S2 performs better in predicting longer time‐scale and slower moving waves (MJO and equatorial Rossby waves), while GraphCast performs better in predicting shorter and faster moving waves (Kelvin and mixed Rossby–gravity waves). However, both models systematically underestimate precipitation amplitude across all wave types, especially over the ...

Validation of a Particle Image Velocimetry Algorithm Through Comparative Field and Laboratory Analysis

River Research and Applications, EarlyView.
ABSTRACT Flow velocity measurement is fundamental to hydrological and hydraulic studies, providing essential data for streamflow estimation and river dynamics analysis. Traditional in situ methods like propeller gauges and acoustic Doppler current profilers are accurate but intrusive and labour‐intensive, while non‐intrusive image processing methods ...

Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

Phase Engineering of Plasma‐Enhanced Atomic Layer Deposited Molybdenum Disulfide Using High Accuracy Direct Writing With Focused Li+ and Ga+ Ion Beams and Ultrashort Pulse Laser

Small, EarlyView.
In the context of phase heterostructures on two‐dimensional materials, a high‐precision direct writing approach is employed. This involves using a focused ion beam to transform molybdenum disulfide to the metallic 1T phase, followed by retransformation via ultrashort pulse laser processing.
