The evaluation of boundary‐layer turbulence in high‐resolution numerical weather prediction simulations using Doppler lidar

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A new method compares both kilometer and sub‐kilometre weather model simulations with Doppler lidar observations to assess the representation of boundary‐layer turbulence. While bulk boundary‐layer properties are well represented, vertical velocity variance is strongly underestimated in both simulations.

The role of the synoptic‐scale conditions in driving fog and mist during the FATIMA July 2022 Sable Island Field program

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ERA5 hourly 325‐m and 1512‐m (a) convergence and (b) vertical motion (actually pressure change with sign reversed to compare with convergence) over Sable Island around the time of an event. The mist (green) and fog (red) occurrences at the surface station are shown at the bottom of the figures. A 325‐m fitted line convergence was positive for the first

New insights into convection‐permitting model simulations from a ZDR$$ {\boldsymbol{Z}}_{\mathbf{DR}} $$ diagnostic for raindrops

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A polarimetric radar forward operator to simulate differential reflectivity (ZDR$$ {Z}_{\mathrm{DR}} $$) from rain was developed to evaluate simulated storms in the Met Office Unified Model (MetUM) for two case days of the Wessex Convection Experiment (WesCon) field campaign. Vertical columns of ZDR$$ {Z}_{\mathrm{DR}} $$, indicative of strong updrafts,

Scale dependence of the marine atmospheric boundary‐layer response to ocean surface‐temperature variability in the EUREC4$$ {\mathrm{EUREC}}^4 $$A region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
With a minimal physics model and a high‐resolution fully 3D simulation, we demonstrate that the marine atmospheric boundary layer (MABL) response to sea‐surface temperature (SST) variability displays a dependence on the horizontal scales of motion.

Modeling rainfall drop size distribution moments using an S‐band polarimetric radar in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Using S‐band dual‐polarization radar and disdrometers during PRECIP 2022 in Taiwan, we analyze a Mei‐Yu frontal event with widespread stratiform rain and embedded convection. Multiple disdrometers are used to create a novel drop size distribution model for S‐band radars resolving both the drizzle and precipitation modes. The model reveals both inferred
