“…(25) Moreover, the climatic characteristics of forest land vary depending on the altitude difference. (26) Our results reflect these findings and indicate that, even if the same tree species is planted in a forest area, the microclimate effects will vary depending on the environmental characteristics of the forest stand, such as elevation, slope, and latitude. To more accurately analyze these environmental characteristics to better understand the climatic characteristics of individual forest stands, a more long-term monitoring effort is required.…”

In this study, we analyzed the characteristics of microclimate in three types of coniferous forest stand in mountainous areas of Korea, categorized as Pinus densiflora Siebold & Zucc. (PD), Pinus koraiensis Siebold & Zucc. (PK), and Larix kaempferi (Lamb.) Carrière (LK). Climate data were obtained using a HOBO data logger installed in each forest stand, and meteorological factors were compared between forest land and nonforest land (weather stations) from July 2015 to May 2017. The differences in daily mean temperature, daily mean maximum temperature, daily mean minimum temperature, and daily mean relative humidity between three study sites and weather stations were significant, except for the daily mean temperature difference at the PD site. The meteorological differences between forest areas and weather stations reflect different forest characteristics such as forest type and tree density. The results also indicate that, even if the same tree species is planted in a forest area, the effects of the microclimate can vary depending on the environmental characteristics of the forest stand such as elevation, slope, and latitude.

“…Olenya Rechka station is located at the same latitude but above the upper boundary of the spruce distribution. Using its data allowed simulation of local temperatures and estimation of the approximate timing of the vegetative season at all three sites, based on the known linear temperature dependence on elevation (Hamlet and Lettenmaier 2005;Chae et al 2012;Wypych et al 2018) and the uniformity of the temperature field within the region.…”

“…The features of the mountains include a significant elevational spread not only of forest ecosystems, but also of individual species of woody plants (Vitasse et al 2009). Examining the growth of one species at different elevations makes it possible to consider the variability patterns of the climatic response from two sides: 1) due to spatial (mostly elevational) temperature gradient with average lapse rate of 0.65°C per 100 m of elevation (Maurer et al 2002;Hamlet and Lettenmaier 2005;Chae et al 2012;Wypych et al 2018); 2) due to the temperature temporal variation at a fixed elevation (Wilmking et al 2004(Wilmking et al , 2005Driscoll et al 2005;Lei et al 2016). However, we hypothesize that due to highly mosaic landscape, in mountains integrity of the observed climate-growth relationships can be achieved only if small-scale (local and individual) factors influencing tree growth are also taken into account.…”

Divergent growth trends and climatic response of Picea obovata along elevational gradient in Western Sayan mountains, Siberia

et al. 2018

In mountain ecosystems, plants are sensitive to climate changes, and an entire range of species distribution can be observed in a small area. Therefore, mountains are of great interest for climate-growth relationship analysis. In this study, the Siberian spruce"s (Picea obovata Ledeb.) radial growth and its climatic response were investigated in the Western Sayan Mountains, near the Sayano-Shushenskoe Reservoir. Sampling was performed at three sites along an elevational gradient: at the lower border of the species range, in the middle, and at the treeline. Divergence of growth trends between individual trees was observed at each site, with microsite landscape-soil conditions as the most probable driver of this phenomenon. Cluster analysis of individual treering width series based on inter-serial correlation was carried out, resulting in two subset chronologies being developed for each site. These chronologies appear to have substantial differences in their climatic responses, mainly during the cold season. This response was not constant due to regional climatic change and the local influence of the nearby Sayano-Shushenskoe Reservoir. The main response of spruce to growing season conditions has a typical elevational pattern expected in mountains: impact of temperature shifts with elevation from positive to negative, and impact of precipitation shifts in the opposite direction. Chronologies of trees, growing under more severe micro-conditions, are very sensitive to temperature during September-April and to precipitation during October-December, and they record both inter-annual and long-term climatic variation. Consequently, it would be interesting to test if they indicate the Siberian High anticyclone, which is the main driver of these climatic factors.

“…Mountainous terrain provides many challenges for the installation and maintenance of meteorological instruments (Chae et al ., 2012). The number of available weather stations in a mountainous region is often insufficient for the complete coverage of the altitude ranges (Rolland, 2003; Wang et al ., 2017).…”

The spatial distribution of surface air temperatures is essential for understanding and modelling high-relief environments. Good estimations of the surface temperature lapse rate (STLR) and the 0 C isotherm height (H0) are fundamental for hydrological modelling in mountainous basins. Although STLR changes in space and time, it is typically assumed to be constant leading to errors in the estimation of direct-runoff volumes and flash-floods risk assessment. This paper characterizes daily and seasonal temporal variations of the in-situ STLR and H0 over the western slope of the subtropical Andes (central Chile). We use temperature data collected during 2 years every 10 min by a 16 sensors network in a small catchment with elevations ranging between 700 and 3,250 m. The catchment drains directly into Santiago, the Chilean capital with more than seven million inhabitants. Resulting values are compared against those obtained using off-site, operational data sets. Significant intraand inter-day variations of the in-situ STLR were found, likely reflecting changes in the low-level temperature inversion during dry conditions. The annual average in-situ STLR is −5.9 C/km during wet-weather conditions. Furthermore, STLR and H0 estimations using off-site gauges are extremely sensitive to the existence of gauging stations at high elevations.
