The Description of the Climate of Moravia by Kryštof Passy from the year 1797
The manuscript of the "Introduction to the Knowledge on the Hereditary Markgraviate of Moravia" as an appendix to the lecture of political science at the Olomouc lyceum written in 1797 by Prof. Kryštof Passy deals also in several paragraphs with the description of the climate of Moravia. The author, departing from the meteorological observations by Josef Gaar in Olomouc, mentions the description of air pressure, temperature and moisture, evaporation and wind. Besides the description of regional peculiarities of the Moravian climate, Passy tries to explain their causes and deals in detail with the effect of eight basic wind directions on changes in air temperature, air moisture and the course of weather from January to July. Passy's description is verified with respect to the results of modern measurements and the present-day knowledge on Moravian climate.
