Dr Joachim Fallmann

Joachim Fallmann works on high resolution coupled prediction

Joachim Fallmann is responsible for verification and evaluation activities for the high resolution UK Environmental Prediction regional coupled modelling system.

Current activities

Joachim is currently part of the UK Environmental Prediction team, working as a meteorological scientist.

UK Environmental Prediction draws together a number of scientists and software developers working at the Met Office and in partner organisations, across modelling aspects of the atmosphere, ocean (including currents, waves and biogeochemistry) and land surface (including hydrology). A Prototype project to build and evaluate a first look regional coupled prediction system for the UK at ~1km scale is currently under way.

Joachim's personal research work within this project is currently aiming to coordinate evaluation and verification efforts for the UK Environmental Prediction prototype system comparing a series of high resolution regional coupled configurations: atmosphere/ocean, ocean/wave, and atmosphere/ocean/wave. Next to the analysis of different coupling techniques he aims to test the benefits of coupling for different weather patterns over the UKV domain and identify observational systems suitable for model evaluation and enhanced process understanding. He focuses on the ocean/atmosphere transition zone and on exchange processes in the marine boundary layer.

Career background

Joachim joined the Met Office in 2015, and since then he has been working in the UK Environmental Prediction team on the regional coupled prediction prototype.

Between 2014 and 2015 Joachim worked as research assistant at the Institute of Meteorology and Climate Research, Atmospheric Environmental Research (IMK-IFU) -Karlsruhe Institute of Technology (KIT), Garmisch-Partenkirchen. During that time he worked on mesoscale simulations of heat- and moisture fluxes over the North Sea using the Weather Research and Forecasting model (WRF). Further he analysed wind field characteristics in complex terrain using a coupled mesoscale-large eddy simulation model (WRF-LES).

During his PhD at the IMK-IFU between 2011 and 2014 he analysed the impact of urban heat island mitigation strategies on urban boundary layer properties and concentration of primary and secondary pollutants in urban environments. He worked on urban canopy parameterization schemes within WRF and regional applications of the mesoscale climate- air chemistry model WRF-Chem.
Joachim completed a PhD in Meteorology at the University of Cologne in November 2014 on  'Numerical simulations to assess the effect of urban heat island mitigation strategies on regional air quality'. From 2005 to 2011 he studied Geography with Physics and Remote Sensing at the Ludwig Maximilians University Munich.
