Evaluating the evolution of cyclone IDAI using the physically based PASM air-sea flux model

Autor: Royston Fernandes, Jean-Luc Redelsperger, Marie-Noelle Bouin

Earth System Models (ESM) and Numerical Weather Prediction (NWP) systems often have large biases in their representation of surface-atmosphere fluxes when compared to observations. Over sea, these biases are more pronounced due to dynamic non-linear

International audience; Estimating accurately dust emission flux during aeolian erosion events is crucial for quantifying the amount of dust in the atmosphere. The rare existing field experiments quantifying such flux were mainly performed using the

Turbulent transport of mineral dust away from erodible plots is usually assumed similar to the momentum transport. However, observations from the WIND-O-V (WIND erOsion in presence of sparse Vegetation's) 2017 field experiment over an isolated flat s

Predicting the particle size distribution (PSD) of near-surface turbulent dust flux ( F wc ) is a key issue for estimating the size of atmospheric mineral dust. Existing dust emission schemes differ in their parametrization of the emitted dust ( F em
