n scientist and a Professor of Meteorology
Meteorology
Meteorology is the interdisciplinary scientific study of the atmosphere. Studies in the field stretch back millennia, though significant progress in meteorology did not occur until the 18th century. The 19th century saw breakthroughs occur after observing networks developed across several countries...

 at the University of Belgrade
University of Belgrade
The University of Belgrade is the oldest and largest university of Serbia.Founded in 1808 as the Belgrade Higher School in revolutionary Serbia, by 1838 it merged with the Kragujevac-based departments into a single university...

. He was the author of first mathematical models of the numerical weather prediction
Numerical weather prediction
Numerical weather prediction uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic...

, which were used operationally in the Weather Service of Yugoslavia from 1970 to 1977. In the same period he began modeling of the atmospheric diffusion of air-pollution and created the first model of the spatial distribution of air-pollution. The output of this model was used for the elaboration of the urban plan of Pančevo
Pancevo
Pančevo is a city and municipality located in the southern part of Serbian province of Vojvodina, 15 km northeast from Belgrade. In 2002, the city had a total population of 77,087, while municipality of Pančevo had 127,162 inhabitants. It is the administrative center of the South Banat...

. For the actual research of the three dimensional distribution of wind energy (on the territories of Belgrade and Serbia) he applied the integration of classic models with GIS technology.

Special area of his engagements were the intentionally and inadvertently modified climates, as well as their impact on the sustainable development
Sustainable development
Sustainable development is a pattern of resource use, that aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come...

. These modifications destabilize the climate system and lead to big material and social damage, due to the lack of possibility of weather control. Petar Gburčik proved this with his scientific papers on weather modifications and climate change
Climate change
Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average...
