Weather and Climate Extremes: Simplex, Dynamical Systems and Hull Clustering

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract A novel method is developed and applied to identify high‐dimensional weather and climate extremes located on the envelope of the data set within its state space. The method is based on formulating and integrating dynamical systems whose attractive set, that is, stable fixed points, is constituted of extreme states residing on the convex hull ...

Geopotential Difference Measurement Using Two Transportable Optical Clocks’ Frequency Comparisons

Remote Sensing
High-accuracy optical clocks have garnered increasing attention for their potential application in various fields, including geodesy. According to the gravitational red-shift effect, clocks at lower altitudes on the Earth’s surface run slower than those ...

Comparison of global geopotential models from the champ and grace missions for regional geoid modelling in Turkey

Studia Geophysica et Geodaetica, 2009
The continuous efforts on establishment and modernization of the geodetic control in Turkey include a number of regional geoid models that have been determined since 1976. The recently released gravimetric Geoid of Turkey, TG03, is used in geodetic applications where GPS-heights need to be converted to the local vertical datum.

Skillful Polar WRF Cloud Modeling of a Warm Winter Atmospheric River at the Antarctic Peninsula

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Atmospheric rivers are episodic events that can advect relatively large quantities of moisture to Antarctica, contributing to both disproportionate precipitation and melting events. The Year of Polar Prediction, an international effort to improve weather prediction over the southern polar region, presents an opportunity to study the clouds and

Moho Interface Modeling Beneath the Himalayas, Tibet and Central Siberia Using GOCO02S and DTM2006.0

Terrestrial, Atmospheric and Oceanic Sciences, 2013
We apply a newly developed method to estimate the Moho depths and density contrast beneath the Himalayas, Tibet and Central Siberia. This method utilizes the combined least-squares approach based on solving the inverse problem of isostasy and using the ...

Influences of Summer Northeastern Arctic Sea Ice on September Compound Heatwave and Drought Events in the South China

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Compound heatwave and drought events (CHDEs) in South China (SC) have intensified in early autumn, yet their driving factor remains unclear. Based on reanalysis data and numerical experiments, this study investigates the potential influence of the summer northeastern Arctic Sea ice concentration (NEASIC) on the interannual variation of ...

Teleconnections Between Warm‐Season Extreme Precipitation Events Over North China and Upstream Regions: Insights From Complex Network Analysis of Climate

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract North China frequently experiences devastating extreme precipitation events (EPEs). Upstream spatiotemporal propagation characteristics of EPEs can provide useful precursors for forecasting North China EPEs but remains poorly understood. Using climate network analysis, two dominant EPEs propagation pathways, that is, a northwestern pathway ...

Constrained gravity inversion unravels the Moho depth and tectonic patterns in China and its adjacent areas

Earth and Planetary Physics
The Mohorovicic discontinuity (Moho) boundary separating the Earth’s crust and mantle reflects the evolutionary trajectory of the Earth’s crust, yielding crucial insights into crustal formation, tectonic evolution, and profound dynamic processes. However,
