Evaluation avant construction de l’impact d’un ouvrage linéaire en remblai sur le risque de gel printanier : exemples sur la LGV est-européenne dans …

2005

Afin d’évaluer dans un vignoble l’incidence sur la fréquence du gel dommageable (t° < -2°C) que pourrait créer un futur remblai de la Ligne à Grande Vitesse Est européenne, une bâche ayant la longueur et la hauteur de cet ouvrage a été installée sur le site des Fonds de Sillery (sud-est de la ville de Reims). Pour les situations météorologiques de type radiatif, des mesures de la température et des écoulements d’air froid, ont été effectuées, durant le printemps 2001, sur 19 points implantés en amont du futur remblai, simulé par une bâche. La comparaison des résultats sans bâche (2 nuits de mesure), puis avec sa présence (3 nuits), montre que cet ouvrage permettra la formation d’un lac d…

Evaluation de l'impact d'un futur remblai de la ligne à Grande Vitesse Est Européenne sur le risque de gel dans le vignoble de Champagne

2002

In order to evaluate for the vineyard, the additional risk of freezing, which could be generated by a railway embankment of the High Speed Line (TGV «Paris-Strasbourg») a canvas cover of the future embankment (length 480 m, height 3 m maxi) was drawn up in the bottom of a wineyard slope. Measurements of Actinothermal Index (AI) Temperatures, at the height of the bud (at 50 cm of the surface) and measurements of of cold air windslopes, were carried out on a microclimatic scale. We recorded 19 points of measurements, without then with the presence of the canvas cover, for the nights characterized by a radiative cooling (wind £ 2m.s-2, clear sky) during spring 2001. The possible incidence of t…

Interannual variability of rainfall in the eastern horn of Africa and indicators of atmospheric circulation

1993

Relationships between rainfall variations in the Eastern Horn of Africa, the Southern Oscillation, and the Indian Ocean temperature and pressure surface fields are studied for the period 1932–83. Rainfall data consist of stations and regional indices calculated for three selected areas experiencing quite different rainfall patterns. The results indicate significant negative correlations between northern autumn rains in Somalia and the Southern Oscillation during the same season. These rains are also negatively correlated with pressure in the Western Indian Ocean, and positively correlated in the Eastern Indian Ocean. The reverse pattern is shown with sea-surface temperature. This agrees ver…
