O článku:
Based on the results of regular monitoring at 11 meteorological stations in the Ukrainian Carpathians, it was discovered a vivid tendency of air temperature increase. It was defined that thermal gradient in the mountains is much less than it is in the free troposphere; at the small altitude it is larger than it is on the tops of mountains. The largest gradient it is observed in period from March till July, the lowest one in period from November till January. It was revealed the cyclical fluctuations of precipitation, in particular the existence of a modern dry phase. There is a tendency of decrease in wind speed during all seasons, which is more evident in the second part of year. There is also the increase in snow cover depth at high altitude. In spite of climate change the river runoff has not changed essentially for the last decades. Like the precipitation the river runoff is of a cyclic nature too. During the last four decades the increase in evaporation, calculated on the base of water balance, has been observed. There is the tendency of runoff increase in a cold period at the large altitude. In turn the water runoff of rivers, located on low-mountain terrain, decreases in the summer period.
