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.

An Ensemble Mean and Evaluation of Third Generation Global Climate Reanalysis Models

Atmosphere, 2018
We have produced a global ensemble mean of the four third-generation climate reanalysis models for the years 1981–2010. The reanalysis system models used in this study are National Centers for Environmental Prediction (NCEP) Climate Forecast System

Exploration of the use of short‐wave infrared radiances in weather forecasts model Part II: Data assimilation and forecast impact assessment

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The standalone non‐local thermodynamic equilibrium (NLTE) bias correction schemes, utilizing a look‐up‐table and a linear regression method developed in Part I and new quality control procedures for short‐wave infrared radiances (SWIR), were tested within a data assimilation framework.

Revealing skill of the MiKlip decadal prediction system by three-dimensional probabilistic evaluation

Meteorologische Zeitschrift, 2016
Decadal climate predictions and their verification are part of ongoing research. This article studies different methods applied to decadal hindcasts of three-dimensional atmospheric variables to evaluate the MiKlip (Mittelfristige Klimaprognosen ...

A case study of temperature tendency mechanisms operating over northern Africa during and following midlatitude winter troughs

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An Iberia‐Central Mediterranean trough sequence (7–10 February 2018) delivers anomalous low‐level temperature tendencies attributable to dynamics across most of northern Africa, with warming over northeastern Africa, especially 10–12 February into the eastern Sahel. An ECMWF product attributes the tendencies (see Figure).

A model intercomparison analysing the link between column ozone and geopotential height anomalies in January [PDF]

Atmospheric Chemistry and Physics, 2008
A statistical framework to evaluate the performance of chemistry-climate models with respect to the interaction between meteorology and column ozone during northern hemisphere mid-winter, in particularly January, is used.

January ozone anomaly over the North Atlantic-European region: Longitude-dependent decadal change in total ozone during 1979-1992

Meteorologische Zeitschrift, 1996
A large decrease in total ozone of up to more than 4 DU/yr occurred over Europe during January 1979-1992. This value is almost twice that of the zonal mean.

Validation of the Aura Microwave Limb Sounder temperature and geopotential height measurements [PDF]

Journal of Geophysical Research: Atmospheres, 2008
Global satellite observations of temperature and geopotential height (GPH) from the Microwave Limb Sounder (MLS) on the EOS Aura spacecraft are discussed. The precision, resolution, and accuracy of the data produced by the MLS version 2.2 processing algorithms are quantified, and recommendations for data screening are made. Temperature precision is 1 K

Physically consistent mesoscale model evaluation in complex terrain

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a novel approach for evaluating mesoscale atmospheric models in complex terrain by selecting physically consistent grid points and applying height‐based corrections. The method corrects for sensor height and terrain elevation differences between model and observations using a time‐varying lapse rate.
