OCEANOGRAPHY AND METEOROLOGY
Starting from the definition of the atmospheric properties and the temporal and spatial variability of air masses, the main mechanisms of regional and large scale circulation will be discussed.Starting from the definition of the sea water properties and the temporal and spatial variability of water masses, the main mechanisms of regional and large scale circulation will be discussed.
Objective of these lessons is to provide the basic knowledge of the dynamic of both the atmosphere and the ocean, to identify the spatial and temporal scale of the main processes and their interactions. Meteorological phenomena are described and quantified by the variables of Earth’s atmosphere: temperature, air pressure, water vapour, mass flow, and the variations and interactions of those variables, and how they change over time. Different spatial scales are used to describe and predict weather on local, regional, and global levels. Starting from the definition of the sea water properties and the temporal and spatial variability of water masses, the main mechanisms of regional and large scale circulation are presented. Simple cases of Navier-Stokes equations solution leading to the geostrophic and wind driven currents description will be discussed. Tides will be characterized in terms of tidal forces and local hydrographic features and the different methods of tidal analysis and prediction will be presented. The effect of non-tidal influences on the sea level variations will be evaluated. Wind waves and swell principles, generation process and regimes will be discussed. As most of these processes are characterized by a well defined temporal scale, an introduction to time series and spectral analysis will be included.
AIMS AND LEARNING OUTCOMES
The characterization of the tide in terms of tidal forces and local hydrographic features and the effect of non-tidal influences on the sea level variations are a particular support to the oceanographic and hydrographic knowledge.
