HOW THE CLIMATE MIGRATES. CASE STUDY FOR FOUR LOCATIONS IN THE CARPATHIAN-BASIN

Abstract

One of the manifestations of climate change is that the climate of a given location becomes similar to the climate of another location. The detection and investigation of these migration effects is useful in several areas, such as tourism or agriculture. The present study attempts to monitor this location-related climate change. Based on daily temperatures and precipitation at four test sites, using the cosine similarity index shows how the climates of each site migrated in the Carpathian Basin. The study examines the similarity values for each location both for ten-and thirty-years periods. We can see that in most cases the climate not only migrates, but in many cases, it shrinks territorially or largely disappears from the study area. In order to be able to process the large amount of data, we used own developed R scripts, which can be reused and expanded in the context of new data or perhaps a more precise methodology.
