Insights Into the Conformational Dynamics of the Cytoplasmic Domain of Metal‐Sensing Sensor Histidine Kinase ZraS

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT ZraS is a metal sensor integral to ZraPSR, a two‐component signaling system found in enterobacters. It belongs to a family of bifunctional sensor histidine kinases (SHKs) and is speculated to sense zinc‐induced stress on the bacterial envelope.

Spatial and temporal structure of the fog life cycle over Atlantic Canada and the Grand Banks

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The relationship between fog occurrence and atmospheric and ocean surface conditions is explored from a 71‐year climatological analysis covering a broad range of spatial and temporal scales of marine fog over Atlantic Canada and the Grand Banks of Newfoundland, Canada. We find that the ocean surface plays a key role as a necessary boundary condition in

Two archetypes of tornadic quasi‐linear convective systems in the United Kingdom: Relevance of horizontal shearing instability to vortexgenesis and maintenance

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Two archetypes of tornadic quasi‐linear convective systems with and without horizontal shearing instability. Modeled surface precipitation rates (mm ·hr$$ \cdotp \mathrm{hr} $$ −1$$ {}^{-1} $$; colored) and absolute vorticity (contours every 3×10−3$$ 3\times 1{0}^{-3} $$ s−1$$ {}^{-1} $$; dashed when negative) after vortexgenesis from the model domain.

Links between hail hazard and climate modes of variability across Australia

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Climate modes of variability influence hail‐prone atmospheric conditions, but links between these drivers and hail hazard across Australia have not been well constrained. We examine relationships between the El Niño Southern Oscillation (ENSO), Indian Ocean Dipole (IOD), and Southern Annular Mode (SAM) and proxy‐derived hail‐prone days across the ...

A radar‐based investigation of precipitation growth and decay in South Korea

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Within a Lagrangian framework, we quantitatively retrieved and assessed precipitation growth and decay using the South Korean radar network, focusing on spatial patterns over the unique geographical features, including complex topography and land–ocean boundaries. Our findings indicate that the precipitation growth and decay is significantly influenced

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

open access: yesQuarterly 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 ...

Spatial verification of global precipitation forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We present an adaptation of the recently developed precipitation attribution distance (PAD) metric, designed for verifying precipitation, enabling its use on the Earth's spherical geometry. The method is fast and flexible, with its behavior analyzed using a set of idealized cases and 7 years of operational global high‐resolution precipitation forecasts.

Sensitivity of near‐surface marine winds and wind stress in coastal Antarctica to regional atmospheric model configuration

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Marine winds near coastal Antarctica are important for sea‐ice variability and ocean circulation. We test the sensitivity of simulated winds to varying uncertain aspects of the atmospheric model configuration. Winds (each configuration a coloured solid line in the figure) are sensitive to model physics, and notably we find that wind stress over a ...

Application of computer vision for off‐highway vehicle route detection: A case study in Mojave desert tortoise habitat

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Our study leverages advanced computer vision models, which we trained on a unique collection of geospatial imagery, to detect off‐highway vehicle (OHV) routes in the Mojave Desert, a critical habitat for the threatened Mojave desert tortoise (Gopherus agassizii).
