“…The Landsat sensors are a useful tool for ensuring the images necessary for the assessment and monitoring of the changes induced to the forest vegetation (Vogelmann et al, 2012). The Landsat images have been pre-processed to calculate the root mean square error (RMSE) for the two images that were used and to convert the digital numbers into the surface reflection according to the established methodologies (Furtuna et al, 2015;Haidu et al, 2017).…”

Windstorms are among the main factors causing damages to forest ecosystems. These meteorological phenomena cannot be predicted, prevented or controlled. They are occurring rapidly and take place in a meteorological context characterized by high velocities of the air currents. This paper analyses the characteristics of the severe meteorological events on 20 July 2011 which have led to windthrows on extended areas within the Apuseni Mountains in the Romanian Carpathians. The study highlights the evolution of the synoptic processes both at regional scale and at mesoscale. The meteorological analysis is carried out based on synoptic maps and by means of the data coming from the doppler WSR-98D radar in Bobohalma. The main results indicate the occurrence of the severe meteorological phenomena against the background of alternating atmospheric circulation types. The main cause is the transition of the zonal circulation into maritime tropical circulation. This contributed to the destabilizing of the warm and moist air masses that have generated strong storms at national level

Detection of Old Diffusive Windthrow Using Low Cost Resources. the Case of Xynthia Storm in the Vosges Mountains, 28 February 2010

Abstract: Unlike the contiguous windthrows, the diffuse windthrows occurred as a result of wind 12 gusts of lower speed (100-140 km/h) than in the first case (>140 km/h) are much more difficult to
