Abstract
Meteorological research has been carried out in Roztocze Region for many years by numerous scientists. Nevertheless, information about its climate is limited to general climatic classifications of Poland. Knowledge about local climates of this specific area is rather limited. In this case study, the authors combined traditional methods of investigating this topic with ground-based thermal IR imaging not used in small-scale climatology so far.

As a conclusion of the investigation, it can be stated that the influence of forest on grassland phytoclimate during advection of cold air can be observed only in a limited range of distances. This interaction changes according to the type of weather, relief of the land and type of vegetation. It is also worth emphasizing that using a handheld thermal IR camera, GIS analysis and satellite imaging can be considerably helpful in research on local climate and extreme thermal phenomena.
