Atmospheric Physics, Meteorology and Climatology

Coordinated by: Department of Atmospheric Physics
Study branch coordinator: doc. RNDr. Petr Pišoft, Ph.D.

The Atmospheric Physics, Meteorology and Climatology programme gives students knowledge and skills in the field of atmospheric properties and related processes. The programme is unique within Charles University in its comprehensive view of the Earth's atmosphere as a dynamical system in a broad interdisciplinary context. In the Czech Republic more widely, this is the only programme giving a comprehensive education in the field of atmospheric physics, meteorology and climatology. The programme assumes a bachelor's degree in physics, in which students will have acquired basic knowledge of physical principles (mechanics, thermodynamics, electricity and magnetism, optics, and others) as well as a proficiency in the associated mathematical methods. The study programme is primarily focused on acquiring theoretical knowledge in the field of atmospheric physics (hydrodynamics and atmospheric thermodynamics), thereby extending previously acquired expertise in this field. Furthermore, skills necessary for practical as well as scientific activities in the field of atmospheric physics are acquired, especially in the fields of numerical mathematics, mathematical statistics, data processing and visualization. Part of the course aims to prepare graduates for core applications of atmospheric physics, such as weather forecasting, air pollution analysis and climate research (including modelling and research of higher atmospheric layers). Other courses on the programme serve to deepen the student's focus on particular specialized topics or to expand knowledge in areas close to other branches of physics (e.g., electrical, optical and acoustic phenomena in the atmosphere and the oceans). Study on this programme includes preparing and submitting a master's thesis, one purpose of which is to apply the competences acquired on the programme, as well as an ability to cooperate in solving an assigned scientific problem.

Profile of graduates and study aims:
Graduates have a wide range of knowledge and competencies in the whole field of atmospheric physics, meteorology and climatology. Their skills allow for a professional focus on basic and applied research as well as involvement in the commercial sector. Graduates have a broad range of careers, for example, in academia, in research institutes and at universities, as well as in industrial development centres specializing in flow studies. In the business environment they are able to apply expert knowledge of statistical techniques, and in the field of crisis management they can utilize their acquaintance with extreme meteorological phenomena. They can also find employment in a number of economic sectors influenced by atmospheric phenomena such as energetics, transportation and agriculture.

Graduates have an extensive and comprehensive knowledge of atmospheric physics, dynamics and thermodynamics of the atmosphere, atmospheric circulation at all spatial scales, problems of electromagnetic and acoustic waves in an atmospheric environment, the theory of hydrodynamic wave processes, the theory of non-linear dynamic systems, the structure and development of the climate system, and natural and anthropogenic climate change. They are familiar with contemporary methods of remote sensing (meteorological radars, lidars, sodars and satellites). They are able to process extensive and complex meteorological and climatological data files and are closely acquainted with mathematical statistics and the associated IT applications.
