TL;DR: In this paper, the authors investigated the feasibility of enhancing the integration of an end-to-end forecasting system for flash and surface-water floods to help increase the lead time for warnings for these events.
Convective-Scale Perturbation Growth across the Spectrum of Convective Regimes
TL;DR: In this paper, the dependence of predictability on synoptic conditio-conditional ensembles has been investigated. But, to fully utilize these forecasts, the dependence on predictability has to be taken into account.

TL;DR: The FRANC project (Forecasting Rainfall exploiting new data Assimilation techniques and novel observations of Convection) has researched improvements in numerical weather prediction of convective rainfall via the reduction of initial condition uncertainty as mentioned in this paper.
Characterisation of convective regimes over the British Isles

TL;DR: In this paper, a convective adjustment timescale is calculated from radiosonde ascents and found to be consistent with that derived from convection-permitting model forecasts for three summers in the British Isles to determine characteristics of convective regimes for this maritime region.
A Physically Based Stochastic Boundary Layer Perturbation Scheme. Part I: Formulation and Evaluation in a Convection-Permitting Model
TL;DR: In this article, the authors present a simple, physically consistent stochastic boundary layer scheme implemented in the Met Office's Unified Model, expressed as temporally correlated multiplicative Poisson noise with a distribution that depends on physical scales.
