Weather forecasting was another aspect of Drohobych's publication. He suggested that by observing atmospheric phenomena, one can predict the weather. He also argued that climatic conditions depended on the latitude of a geographic location. One of the most important aspects of this treatise was the author's vision that the world is not an abstract notion and that humans are capable of learning its patterns and laws. In the foreword to the treatise, Drohobych wrote that even though our eyes cannot see the end of the boundless skies, our mind can. That we learn from the effect about the cause and from the latter we truly learn.
