Analysis inter decadal of climate variability facing projections of the CMIP5 models and its involvement in the agricultural production of Venezuela
Agriculture is the largest employer in the world and is probably the most dependent on the climate of all human activities. In recent years there have been events that have put in evidence the vulnerability of global food security to major meteorological phenomena, both in global agricultural markets and the world economy. The food price crisis and the subsequent economic crisis reduced the purchasing power of large segments of the population in many developing countries, which seriously reduced their access to food and thus undermined their food security. During the years 2009 and 2010 in Ven ...
Guidelines for the Assessment of Uncertainty for Hydrometric Measurement
In view of the increasing pressure on water resources, National Hydrological Services (NHSs) worldwide are faced with the challenge to deliver hydrological services of high quality, timeliness and proven credibility, to assist the decision making process of water and natural resources managers. Nowadays, it is commonly expected that these services must be based on information that includes an accurate assessment of its uncertainty. Stream discharge, the basic hydrological variable, is no exception, yet most measurements are still reported as a value without any information on its associated un ...

Progrès réalisés dans l’observation et la prévision du phénomène ENSO
Bulletin, Vol. 64(1). OMM, 2016Les gouvernements, les entreprises du secteur privé et les particuliers sont de plus en plus exigeants lorsqu’il s’agit de la qualité des services climatologiques, d’où l’importance du Cadre mondial pour les services climatologiques (CMSC). Cependant, certaines composantes du réseau d’observation de l’océan – pourtant essentielles à la prestation de ces services – risquent de se dégrader, et les systèmes de prévision climatique ont du mal à rester au fait des attentes croissantes quant à l’exactitude et à la fi abilité des services.1234
