Description

Scientific studies where transport in the atmosphere plays an important role would benefit from a Lagrangian re-analysis that provides meteorological data along continuous trajectories.
We will present our plans for the creation of a novel Lagrangian re-analysis which will help answering a range of scientific questions about energy and water vapour transport and energy conversions in the atmosphere, and the dynamic processes leading to extreme events of temperature, wind and precipitation. For example, using a precursor of the final Lagrangian dataset, anomalies in atmospheric transport were causally linked to ENSO teleconnections in a recently submitted paper by our group.
The Lagrangian particle dispersion model FLEXPART is driven off-line with data from the ERA-5 re-analysis, which translates the Eulerian information into a Lagrangian analogue. The data will eventually be stored in an easily searchable database and shared with researchers worldwide.
