Anticlastic Curvature and Material Freedom

physica status solidi (b), EarlyView.
Anticlastic curvature occurs in bent bars for positive Poisson's ratio; synclastic curvature occurs for negative Poisson's ratio provided the material is homogeneous and elastic. Some planar negative Poisson's ratio materials exhibit anticlastic saddle curvature rather than convex curvature in bending due to effects of 3D structure.

Differential reflectivity columns and hail: Linking C‐band radar‐based estimated column characteristics to crowdsourced hail observations in Switzerland

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Differential reflectivity columns (ZDRC$$ {Z}_{\mathrm{DR}}C $$) have been detected automatically on a composite of radar data derived from five operational C‐band dual‐polarization Doppler weather radars in Switzerland. The characteristics of the detected ZDRC$$ {Z}_{\mathrm{DR}}C $$ are linked to a large sample of 173,000 crowdsourced hail ...

Rapid versus slow intensification of idealized tropical cyclones using soundings from reanalysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Climatologically averaged environmental wind and moisture around intensifying tropical cyclones are used in an idealized model to further discriminate differences between ensembles of rapidly (RI) and slowly (SI) intensifying storms. On average, RI storms have lower vertical tilt, are more axisymmetric, and less ventilated at onset than SI storms, and ...

A consistent coupling of two‐moment microphysics and bulk ice optical properties, and its impact on radiation in a regional weather model

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a novel, consistent coupling of two‐moment microphysics (i.e., ice mass mixing ratio and number) with bulk ice optical properties, providing improved accuracy in radiative transfer simulations. The parametrisations, based on the mass‐equivalent spherical radius, avoid uncertainties associated with the effective radius by directly ...
