A Bayesian Hydrometeor Classification Algorithm for C-Band Polarimetric Radar
Remote Sensing, 2019 A hydrometeor classification algorithm is developed by applying Bayes’ theorem to C-band polarimetric weather radar measurements. The Bayesian hydrometeor classification algorithm (BHCA) includes eight hydrometeor types: hail, rain, graupel, dry ...

How sensitive are Sahelian mesoscale convective systems to cold‐pool suppression?
Quarterly Journal of the Royal Meteorological Society, EarlyView.Cold pools are a ubiquitous feature of mesoscale convective systems (MCSs) with important upscale impacts on West African climate, but their role in the maintenance of tropical MCSs remains debated. Using a 40‐day model with explicit convection and no rainfall evaporation, we show that cold pools do not play a primary role in Sahel MCS development or ...

Air–sea interaction in medicanes with atmosphere–ocean–wave coupled regional climate simulations
Quarterly Journal of the Royal Meteorological Society, EarlyView.The atmosphere–ocean–wave coupling improved storm intensity compared to standalone atmosphere setting, which tended to overestimate wind speeds. The atmosphere–ocean coupling in medicane simulations leads to increased sea surface temperatures, which enhances evaporation and promotes the development of convective systems through increased latent heat ...

Two-dimensional simulations of katabatic layers observed during the GIMEX experiment [PDF]
Annales Geophysicae, 1999 The hydrostatic model SALSA is used to simulate a particular event observed during the Greenland Ice Margin EXperiment "GIMEX" (on July 12th, 1991).

Quarterly Journal of the Royal Meteorological Society, EarlyView.In this paper, we compare atmospheric water vapour data acquired with lidars during the WaLiNeAs programme with data from the ECMWF ERA5 reanalysis. The WaLiNeAs field measurement campaigns took place in autumn/winter 2022/2023 over the French Mediterranean basin and in summer 2023 near Toulouse.

Quarterly Journal of the Royal Meteorological Society, EarlyView.This study analyzed the impact of two mesoscale cyclones on the meteorology and glaciology of South Shetland Islands (SSI) glaciers, using in‐situ observations, ERA5 reanalysis data, and high‐resolution weather and glacier mass balance models. Mesoscale cyclones drive temperature drops, heavy snowfall, and strong winds over the SSI, significantly ...

Multistep variational data assimilation: important issues and a spectral approach
Tellus: Series A, Dynamic Meteorology and Oceanography, 2016 In this paper, two important issues are raised for multistep variational data assimilation in which broadly distributed coarse-resolution observations are analysed in the first step, and then locally distributed high-resolution observations are analysed ...

Effects of the urban land use on a severe convective windstorm
Quarterly Journal of the Royal Meteorological Society, EarlyView.Numerical simulations with the Weather Research and Forecasting model coupled with the Building Effect Parametrization–Building Energy Model multilayer canopy model were conducted to investigate the impact of urban land use on a severe convective windstorm in Milan, northern Italy, on July 25, 2023.

Observation and backward trajectory of an inertio-gravity wave in the lower stratosphere [PDF]
Annales Geophysicae, 2001 A Doppler lidar observation of an inertio-gravity wave in the mid-latitude lower stratosphere is presented. The wave packet characteristics (vertical and horizontal wavenumbers, intrinsic and apparent frequencies) are inferred from the analysis ...

Spatial and temporal patterns of SST uncertainty
Quarterly Journal of the Royal Meteorological Society, EarlyView.This figure summarises the change in the Operational Sea Surface Temperature and Sea Ice Analysis near‐real‐time sea‐surface temperature product uncertainty spatial pattern in the UK domain as cluster maps broken into three time periods: (a) June 2007–February 2014; (b) March 2014–February 2018; (c) March 2018–December 2022.
