Cloud Cover over the Sahara during the Summer and Associated Circulation Features

Autor: Nada Selami, Geneviève Sèze, Marco Gaetani, Jean-Yves Grandpeix, Cyrille Flamant, Juan Cuesta, Noureddine Benabadji

Publikováno v: Atmosphere, Vol 12, Iss 4, p 428 (2021)

Over the Sahara in summer, the activity of the Saharan thermal low pressure system (SHL), which is linked to the West-African monsoon dynamics and the mid-latitude circulation, is modulated by dust concentration and water-vapor transport. In this con

Autor: Nathalie Philippon, Guillaume Cornu, Lou Monteil, Valery Gond, Vincent Moron, Julien Pergaud, Geneviève Sèze, Sylvain Bigot, Pierre Camberlin, Charles Doumenge, Adeline Fayolle, Alfred Ngomanda

Publikováno v: Environmental Research Letters, Vol 14, Iss 3, p 034007 (2019)

Rainfall thresholds under which forests grow in Central Africa are lower than those of Amazonia and southeast Asia. Attention is thus regularly paid to rainfall whose seasonality and interannual variability has been shown to control Central African f

Secondary sulphate aerosols and cirrus clouds detection with SEVIRI during Nabro volcano eruption

Autor: Geneviève Sèze, Bernard Legras, Pasquale Sellitto

International Journal of Remote Sensing, Taylor & Francis, 2017, 38 (20), pp.5657-5672. ⟨10.1080/01431161.2017.1348635⟩

Secondary sulphate aerosols (SSAs) and cirrus clouds in the upper troposphere–lower stratosphere (UTLS) are two key atmospheric constituents that can modulate the Earth’s radiative balance. In this article, we present a new preliminary detection

We present a simple algorithm that calculates the cloud occurrence frequency at an altitude site using automatic camera image analysis. This algorithm was applied at the puy de Dô

Importance of boundary layer mixing for the isotopic composition of surface vapor over the subtropical North Atlantic Ocean

Autor: Gilles Reverdin, Geneviève Sèze, Camille Risi, Marion Benetti, Giovanni Aloisi

Publikováno v: Journal of Geophysical Research: Atmospheres. 120:2190-2209

During the summer 2012, we carried out continuous measurements of the isotopic composition (δ) of water vapor over the near-surface subtropical North Atlantic Ocean (STRASSE cruise). In this region of excess evaporation, we investigate the control o

Atmospheric Chemistry and Physics, 2016, 16 (11), pp.6841-6861. ⟨10.5194/acp-16-6841-2016⟩

In this paper we combine SO2 and ash plume dispersion modelling with satellite and surface remote sensing observations to study the regional influence of a relatively weak volcanic eruption from Mount Etna on the optical and micro-physical properties
