Short description

The goal of this program is to extend the knowledge of BSc level students, and to learn about different meteorological phenomena, their driving forces, and to gain knowledge on the state-of-the-art methodology that is used in the practice and also about climate change and its environmental consequences. Students have to learn about the multidisciplinary nature of meteorology and the possible connections with different other scientific fields and sectors. 

This program is recommended to applicants who have strong background in physics, mathematics and meteorology or environmental science. Applicants should have deep motivation and ability to learn about the theory of weather forecast and climate modelling, and they should be able to apply their knowledge in the practice. Applicants should be able to understand the different spatial scales that are associated with the variety of meteorological phenomena.

This program enables students to gain knowledge about the methods and tools that represents today’s meteorology and cutting edge research. With the MSc degree they will have the skill set to be able to apply the practice, measurement and observation-oriented analysis methods, as well as the knowledge of weather forecasting and climate modelling. Depending on their ambitions they will be able to continue their studies in a PhD program. The courses are divided into two parts. Students have compulsory courses covering general meteorology required for everybody (e.g. fluid dynamics, dynamic meteorology, informatics, climatology, synoptic meteorology, environmental protection). By the end of the first semester the students have to choose a specialization: weather forecaster or climate researcher. The specialization will cover 30 credits of compulsory classes in the next three semesters. The courses for the specializations cover the full spectrum of the selected field. Students with missing background in a particular field of meteorology are required to fulfill prescribed BSc classes up to 20 additional credits. The master thesis work that is due to the end of the 4th semester is taken into account as 20 credits.

Specializations: weather forecaster, climate researcher

 

Strength of program

The Meteorology MSc program offers high level of theoretical meteorology courses as well as diverse courses on applications. Students are encouraged to participate in the research projects of the professors, where they can learn the latest research methods and acquire experience in teamwork. Students who spend extra work on a subject lead by their professors can participate in a national scientific competition among students from all universities. In addition to the faculty members, lead researchers of the Hungarian Meteorological Service, the Meteorology Division of the Hungarian Military, and the Meteorological Service of the Liszt Ferenc International Airport also offer thesis supervision. This helps the students find the most appealing topic for their thesis lead by the most appropriate expert.
