Ponocná T. et al. (2018): Deviations of treeline Norway spruce radial growth from summer temperatures in East-Central Europe. Agricultural and Forest Meteorology 253–254, 62–70.

There is increasing evidence of recent decoupling of tree-ring growth from observed temperature rise. We explored coherency of treeline radial growth and temperature trend in mountain regions of Central Europe. We found a period of low intraregional growth coherency in the 1950s reflecting warmer, less temperature-limiting conditions and land usechange. Highly coherent growth in the 1930s, 1970s and 1980s was related to the strong environmental growth-limiting signals of short growing seasons and high acid pollution loads.

Pokorná, L. et at. (2018): Annual cycle of temperature trends in Europe, 1961–2000. Global and Planetary Change 170 (2018) 146–162.

This paper introduces a new method of analysing temperature trends within a calendar year using a sifting seasons. Annual courses at 135 stations over Europe show a spatial differences of temperature trends and their variability during the calendar year. The method also demonstrates that the choice of the sliding season length and its position within the calendar year strongly affect the sign and magnitude of trends. Homogenous regions with typical annual cycle of trends were identified and some possible causes of temperature changes are mentioned.

Chandler, B.M.P. et al. (2018): Glacial geomorphological mapping: A review of approaches and frameworks for best practice. Earth-Science Reviews, 185, 806-846.

Our paper provides a review paper and assessment of glacial geomorphological methods and datasets currently available. Key challenges to accurate and robust geomorphological mapping are highlighted and the importance of combining multiple datasets and/or mapping approaches is emphasised.


Jenicek, M. et al. (2018): Modeling of future changes in seasonal snowpack and impacts on summer low flows in Alpine catchments, Water Resources Research, 54 (1), 538-556.

It is expected that an increasing proportion of the precipitation will fall as rain rather than snow in the future due to  increase in air temperature. Our study was focused on implications of the mentioned change on summer low flows and confirmed that 1) In snow-dominated areas, summer low flows will decrease in the future, while 2) this decrease will be caused mostly by the decrease in snow storage and the shift of snowmelt season. The study also showed that 3) low flows at higher elevations are more sensitive to the decrease in snow storage than low flows at lower elevations. This might affect water availability during summer.
