METEOROLOGY AND OCEANOGRAPHY
Lectures are in Italian. The professor is available to interact with students in English
The educational objectives of the course are related to the knowledge of the main properties of the ocean and of the atmosphere as well as their dynamics at several spatial and temporal scales. Additionally, the equations of oceanic and atmospheric motions will be described also through some simplifications.
Students shall prove to know the characteristics of the main oceanographic and atmospheric phenomena. The course also aims at increasing the ability of reading graphs, maps and bulletins associated to oceanographic and meteorological data.
Students shall prove to apply the main theoretical and practical knowledge acquired during the course in order to identify and describe the observed oceanographic and meteorological phenomena.
Students shall autonomously evaluate any advantage or danger associated to the oceanographic and meteorological dynamics, focusing on weather conditions that result in a danger for the navigation.
Students shall acquire the skill of reading, understanding and transmitting the informations obtained through any oceanographic bulletin, forecast or observation.
Students shall be capable of continuously update their knowledge, by reading books, articles and oceanic and weather forecasts and bulletin, in order to guarantee a state of the art information of the sea and weather state to the navigation officers.

1. Equations of motions analysis.
2. reading a thermodynamic diagram.
3. reading a T/S diagram.

Following the attachment 1 of the MIT decree dated 19th December 2016 the following competencies required will be acquired in meteorology (30 h):
a) Interpretation of meteorological data obtained through onboard instruments;
b) Knowledge and understanding of the different meteorological systems and their reporting;
c) Use of available meteorological data.
The course deals with the basic elements required to study the atmosphere and the ocean properties and dynamics. The main physical properties of ocean and atmosphere, as well as the main processes will be described in a first descriptive session of the course. Then the equations of oceanic and atmospheric motions and their thermodynamics will be discussed.
The course gives some competencies required by the STCW Convention, as amended, for Deck Officers at Operational Level, embodied in the MIT decree dated 19th December 2016, namely “Percorso formativo per accedere alle figure professionali di Allievo Ufficiale di Coperta e Allievo Ufficiale di Macchina”.
Particularly, the course gives the following competencies, listed in the Attachment I of the above-mentioned decree, for Deck Officer Cadets:

Powerpoint presentations and pdf files will be provided during the course.
The exam consists of verifying the achievement of the previously defined educational goals, by an oral examination during which students shall discuss the main topics of the course,in order to evaluate the autonomous capacity of reading and comprehension.
Lectures are in Italian. The professors are fluent in English and are available to interact with students in English, also during the examination
