Further information


Climatic variation in the growing seasons of the 1990s was examined using 10-day values for the normalised difference vegetation index (NDVI) in five regions in Poland. The NDVI values were compared with climatic conditions, by calculating multiple correlation coefficients and regression equations for the 10-day means of NDVI on the one hand, and temperature, precipitation, and sunshine anomalies on the other, in the period between April and September. The frequency of appearance of forest fires was analysed for the same regions. The relationships between the frequency of occurrence of forest fires and NDVI values, air temperature, and precipitation were identified.

Keywords: climate variations, vegetation, normalised difference vegetation index (NDVI), forest fires
