Scale interactions of deep convection in the Sahel: Exploring ring patterns in lagged cross‐correlations of rainfall

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Spatio‐temporal patterns in rainfall are evidence of scale interactions in convection in the West African Sahel. Radial normalization of two‐dimensional conditional probability maps reveals a ring‐like structure in rainfall probabilities surrounding previous rainfall.

Evaluation of the WRF model for simulating deep convection and cold‐pool characteristics relevant to wind‐energy applications in Germany

open access: yesQuarterly 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 ...

On the meridional asymmetry of the poleward‐displaced intertropical convergence zone

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We analyze the complex, asymmetrical dynamical structure of the intertropical convergence zone (ITCZ) in the East Pacific and Atlantic basins, seen during boreal summer, using a global, coupled storm‐resolving simulation. The equatorial pressure gradients lead to the acceleration of southerlies, which decelerate when the zonal flow becomes westerly ...

Moist convection and radiative cooling: Dynamical response and scaling

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

The stratospheric gravity wave field produced by a supercell

open access: yesQuarterly 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.
