The Department of Meteorology and Climatology at Aristotle University of Thessaloniki (Inaugural Ministerial Decision No. B1/70/22-4-1983) is a continuation of the Laboratory of Meteorology and Climatology established by the Article 1 of the 16-01-1929's Decree. Within these eighty (80) years, the Department has been presenting a consistent and continuous research, scientific and educational activities.


Research Interests

Over time, the scientific interests of the members of the Department of Meteorology and Climatology focus on issues regarding meteorological processes in the atmosphere and the environment, climate and climate change. Emphasis has been given to extreme weather events, such as heavy rainfalls and floods, droughts and water shortages, thunderstorms and hailstorms with special care on how to address hailstorms for the benefit of man, namely the reduction of hailstorms for the increase of precipitation. Climate change is being investigated by the members of the Department for three (3) decades now. Climatic characteristics of Greece have been studied in detail, in whole or separately. Such studies are necessary, forming the basis for any reference to climate change. The various "scenarios" of the General Circulation Models (GCMs) of the atmosphere, which are used to express the effects of the "greenhouse effect" on agricultural or urban environment, require detailed knowledge and existence of climatic data of the study area. Past years' weather synoptic types have been and are being studied, especially for the region of Central and Southeastern Europe, but also for the wider area of Greece. These weather synoptic types have been associated with the prevailing weather conditions, establishing a complex investigation of many atmospheric phenomena in many physical scales (synoptic, mesoscale, regional), such as:

  • Case studies of agricultural drought and its effects
  • Case studies of precipitation extremes accompanied by local floods
  • Case studies of warm or cold air masses intrusions

Weather Modification is considered as a great aspect to the interests of the Department's members. Hailstorms, precipitation, fog and freezing conditions have been studied in depth, contributing to the sophisticated design and the scientific management undertaking of hail suppression and precipitation or snow enhancement programmes, both in Greece and Italy, by the DAPHNE's proposal coordinator, Prof. Theodore Karacostas. Prof. Theodore Karacostas has significantly contributed to the implementation of the Greek National Hail Suppression Program (NHSP) which covers two agricultural areas over central (Thessaly) and northern (Central Macedonia) Greece from 1984 until today, in collaboration with the Centre of Meteorological Applications (KE.M.E.) of Greek Agricultural Insurance Organization (ELGA) and the 3D s.a General Aviation Applications Inc. At the same time, a number of doctoral dissertations (PhD), theses (MSc) and bachelor dissertations specialized in Weather Modification have been accomplished in the Department, as well as appearances in publications and measurements and data allocation to a number of Scientific Institutions.

The Department of Meteorology and Climatology operates a conventional meteorological station from 1930's January 1st until today. A huge, continuous and reliable dataset of meteorological observations at hourly or daily basis allow the researchers of the Department to conduct a variety of scientific studies. Additionally, the continuous operation of the alpine meteorological stations should be mentioned, at Olympus Science Centre (EKO) on top Agios Antonios (2817 m) of Mt. Olympus, from 1962 until 1972 during summer time and at Training Centre of Mountain Games (KEOA), from 1962 until today. Furthermore, for different periods and without ensuring continuity over time, several other meteorological stations located in the major area of ​​Thessaloniki (EKO, Xylopan, Kalamaria, Panorama, Halkidiki, etc.) operated for an extended period of time or are still operating. Measurements obtained from the aforementioned stations are monitored, recorded and decoded by the staff of the Department while the majority of this dataset has been digitally registered. It is a massive database with data regarding various variables of the atmosphere which can give reliable information on the weather and climatic conditions in the region of Thessaloniki, for the covered period.
