Typology of intraseasonal oscillations based on a Local Mode Analysis
2007
The Intraseasonal Oscillation (ISO; 20-120 day) is an important component of the variability of the Tropical convection that strongly perturbs the Asian and the Aus- tralian monsoons. Our knowledge of the physical origin of the ISO however remains largely incomplete, partially because of the large variability of its characteristics from one event to another. The aim is to determine how the patterns of the different ISO events may be objectively regrouped in a few types, related for example to season, ENSO or other large scale forcing. Patterns of the different ISO events are extracted using a Local Mode Analysis (LMA, Goulet and Duvel 2000). The LMA is based on complex empirical orthogonal …

Influence de l'Oscillation de Madden-Julian sur la variabilité intrasaisonnière des pluies en Afrique de l'Est (Kenya-Tanzanie)
2005
Les incidences de l'Oscillation de Madden-Julian, mode de variabilité atmosphérique intrasaisonnier dominant dans la bande tropicale, sur la répartition des pluies d'Afrique de l'Est durant le trimestre Mars-Avril-Mai, sont étudiées sur la période 1979-2002. L'analyse révèle une modulation significative des précipitations. Cependant, de fortes hétérogénéités existent du point de vue des pluies entre les Hautes terres et la côte kenyane, couplées à des mécanismes pluviogènes de nature différente.

Régionalisation d'un indice agro-climatique en Bourgogne
2009
National audience; Global climate change affects not only common farm crops, but also vineyard yields, the effects of which are commonly observed in both the phenological stages of the vine and the features of the finished product. Vine production is strongly affected by local climate variation. Unfortunately, General Atmospheric Circulation Models are lacking to accurately reproduce useful local climate pattern. The use of Regional Atmosphere Circulation Models offers a great opportunity towards climate impact studies. In this paper, we assess the ability of the WRF (Weather Research and Forecasting) regional climate model to reproduce climate variability in the Burgundy region during the …
