Lidar research activities in Potenza, Southern Italy
, 2003 The lidar group in Potenza has almost 10 years' experience in the field of lidar research. Important results have been accomplished both in aerosol and water vapour research. The lidar system in Potenza has acquired different confi gurations during the

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.

Scaling turbulence drives the general circulation
Quarterly Journal of the Royal Meteorological Society, EarlyView.The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

Wavelet covariance approach to measure convective boundary‐layer structure
Quarterly Journal of the Royal Meteorological Society, EarlyView.This study introduces a wavelet‐based framework that applies the Haar discrete wavelet transform (DWT) to radiosonde profiles of potential temperature and water vapor mixing ratio for diagnosing convective boundary‐layer (CBL) structure. The method objectively identifies key CBL parameters, including the surface‐layer height, entrainment zone depth ...

Increasing urban flash flood risk attributable to both climate and development
Quarterly Journal of the Royal Meteorological Society, EarlyView.A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

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

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study investigates the thermodynamic and microphysical characteristics of updrafts and downdrafts of tropical deep convective anvil clouds using in situ measurements. We found that parts of the downdrafts are in ice supersaturation in these clouds.

Progressive emergence of canopy gravity waves during the afternoon–evening transition
Quarterly Journal of the Royal Meteorological Society, EarlyView.Large‐eddy simulations are used to investigate the afternoon‐to‐evening transition of turbulence over a forest canopy and its coupling with atmospheric boundary‐layer dynamics. As surface cooling strengthens stability and weakens near‐canopy winds, canopy turbulence transitions progressively to internal gravity waves that dominate the evening flow ...
