Abstract Squall lines are substantially influenced by the interaction of low‐level shear with cold pools associated with convective downdrafts. Beyond an optimal shear amplitude, squall lines tend to orient themselves at an angle with respect to th

International audience; Water isotopes are tracers of convective processes and are often used as proxies for past precipitation. These applications require a better understanding of the impact of convective processes on the isotopic composition of wa

We propose an effective geometrical approach to recover the normal form of a given Elasticity tensor. We produce a rotation which brings an Elasticity tensor onto its normal form, given its components in any orthonormal frame, and this for any tensor

What controls the mesoscale variations in water isotopic composition within tropical cyclones and squall lines? Cloud resolving model simulations

Autor: Camille Risi, Françoise Vimeux, Clarisse Dufaux, Grégoire Védeau, Caroline Muller, Sophie Abramian, Peter N. Blossey

One way to test our understanding of the impact of convective processes on the isotopic composition of water vapor and precipitation is to analyze the isotopic mesoscale variations during...

Investigating tropical squall lines with a cloud resolving model

Autor: Sophie Abramian, Caroline Muller, Camille Risi

Investigating tropical squall lines with a cloud resolving modelUsing a cloud resolving model, we attempt to clarify the physical processes responsible for the organization of deep clouds into squall lines in the tropics. To do so, we impose a vertic
