Última An autoregressive model with time-varying coefficients for wind fields ArchiMer Ailliot, Pierre; Monbet, Valérie; Prevosto, Marc. In this article, an original Markov-switching autoregressive model is proposed to describe the space-time evolution of wind fields. At first, a non-observable process is introduced in order to model the motion of the meteorological structures. Then, conditionally to this process, the evolution of the wind fields is described using autoregressive models with time-varying coefficients. The proposed model is calibrated and validated on data ill the North Atlantic. Tipo: Text Palavras-chave: Markov switching autoregressive model; Wind fields; Space time model.

Octubre-noviembre de 1999 OceanDocs Reta, R.; Perrotta, R.G.; Garciarena, A.D.. Results obtained during a research cruise carried out along the coastal area of Mar del Plata (Buenos Aires, Argentina) in November 1999 are presented. The objective of the research cruise was to estimate chub mackerel (Scomber japonicus) abundance with acoustic methods and establish its relation to the hydrographic conditions. The information gathered was complemented with data of catches obtained by a commercial vessel that operated simultaneously in the study area. Environmental data from other research cruises and satellite information were also taken into account to obtain contemporary sea surface temperature and wind speed and direction data. The main species of catches of the research cruise and commercial vessel were horse mackerel (Trachurus...
