A study of a free convective boundary layer using a parcel‐based Lagrangian model
Quarterly Journal of the Royal Meteorological Society, EarlyView.We study the development of a convective boundary layer forced by surface heating and growing into a stably stratified atmosphere above. We compare our results with several recent comprehensive direct numerical simulation (DNS) studies and find broad agreement, and often close quantitative agreement, despite fundamental differences in the numerical ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.We exploit the Field Experiment on Sub‐mesoscale Spatio‐Temporal Variability in Lindenberg (FESSTVaL) to compare the performance of an NWP model at sub‐km resolutions with a traditional LES model. Focusing on clear‐sky ABL turbulence (June 14), shallow convective clouds and surface radiation (June 27), and deep convective cold pools (June 29), we find ...

Quarterly Journal of the Royal Meteorological Society, EarlyView.We use active remote sensing from a ship during the EUREC4$$ {\mathrm{EUREC}}^4 $$A campaign to characterize the environment before, during, and after precipitation in shallow convection. (1) Shallow clouds barely precipitate (only virga). Congestus clouds generate precipitation, occurring less often in the afternoon but with higher cloud fractions. (2)

Quarterly Journal of the Royal Meteorological Society, EarlyView.Deep convection and cold‐pool characteristics over Germany during July 2023 are investigated using Deutscher Wetterdienst (DWD) radar observations and a Weather Research and Forecasting (WRF) model simulation. The temporal evolution of convective cell features reveals a downward‐facing parabolic pattern in both WRF and observations, in terms of cell ...

The stratospheric gravity wave field produced by a supercell
Quarterly Journal of the Royal Meteorological Society, EarlyView.Supercells are a class of long‐lasting thunderstorms with rotating updrafts that often cause severe weather, hail, and tornadoes. This study uses numerical simulations to characterize the stratospheric gravity waves that are caused by these storms.

Mesoscale dynamics of cyclone Leslie (2018): A diagnostic analysis of a rare Iberian landfall
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study presents a successful numerical simulation of cyclone Leslie (2018), using WRF‐ARW v4.5.1. Several mesoscale dynamics were identified indicative of the occurrence of sting jet and cold conveyor belt, which potentiated the record‐breaking winds in central Portugal.

Classification of Fog Life‐Cycle Phases Using Ground‐Based and Satellite‐Based Observations
Quarterly Journal of the Royal Meteorological Society, EarlyView.In this study, the life‐cycle phases of radiation fog events—formation, maturity, and dissipation—are automatically classified at a ground station in Southwest Germany based on visibility trends and thresholds. We demonstrate that visibility detects radiation fog phases effectively, while its combination with ceilometer data can detect the life‐cycle ...
