“…Thus, the positive correlation between NDVI and precipitation in these regions is logical (Piao et al, 2006b). The decreasing Palmer Drought Severity Index (PDSI) in recent decades may intensify the drought stress in temperate grasslands (Cao et al, 2010(Cao et al, , 2011, pointing a decreasing trend of the positive effect of precipitation on vegetation growth in recent years. In desert areas, the weakening contribution of precipitation may be offset by increases in ice and snow melting due to increasing temperature .…”

“…The study of the response of vegetation growth to climate change on regional, continental, and global scales is receiving increasing attention (Myneni et al, 1997;Zhou et al, 2001;Lucht et al, 2002;Piao, 2003;Piao et al, 2006aPiao et al, , 2014Anderson et al, 2010;Peng et al, 2011;Wu et al, 2012). Recent research has indicated a weakening relationship between inter-annual temperature variability and northern vegetation activity over the past three decades (Piao et al, 2014).…”

a b s t r a c tThe weakening relationship between inter-annual temperature variability and vegetation activity in the Northern Hemisphere over the last three decades has been reported by a recent study. However, how and to what extent vegetation activity responds to climate change in China is still unclear. We applied the Pearson correlation and partial correlation methods with a moving 15-y window to the GIMMS NDVI dataset from NOAA/AVHRR and observed climate data to examine the variation in the relationships between vegetation activity and climate variables. Results showed that there was an expanding negative response of vegetation growth to climate warming and a positive role of precipitation. The change patterns between NDVI and climate variables over vegetation types during the past three decades pointed an expending negative correlation between NDVI and temperature and a positive role of precipitation over most of the vegetation types (meadow, grassland, shrub, desert, cropland, and forest). Specifically, correlation between NDVI and temperature (P NDVI-T ) have shifted from positive to negative in most of the station of temperature-limited areas with evergreen broadleaf forests, whereas precipitationlimited temperate grassland and desert were characterized by a positive P NDVI-P . This study contributes to ongoing investigations of the effects of climate change on vegetation activity. It is also of great importance for designing forest management strategies to cope with climate change.

“…First, we aggregated the half-hour data set onto a daily time scale. Only if valid values for one day comprised more than 90% of all measurements (48) were the maximum (T max ), minimum (T min ) and mean temperatures (T mean ) of that day calculated. Second, we aggregated the daily T max , T min and T mean into monthly and annual averages when the valid daily values comprised more than 90% of days in the whole year.…”

Local Effects of Forests on Temperatures across Europe

Forests affect local climate through biophysical processes in terrestrial ecosystems. Due to the spatial and temporal heterogeneity of ecosystems in Europe, climate responses to forests vary considerably with diverse geographic and seasonal patterns. Few studies have used an empirical analysis to examine the effect of forests on temperature and the role of the background climate in Europe. In this study, we aimed to quantitatively determine the effects of forest on temperature in different seasons with MODIS (MODerate-resolution Imaging Spectroradiometer) land surface temperature (LST) data and in situ air temperature measurements. First, we compared the differences in LSTs between forests and nearby open land. Then, we paired 48 flux sites with nearby weather stations to quantify the effects of forests on surface air temperature. Finally, we explored the role of background temperatures on the above forests effects. The results showed that (1) forest in Europe generally increased LST and air temperature in northeastern Europe and decreased LST and air temperature in other areas; (2) the daytime cooling effect was dominate and produced a net cooling effect from forests in the warm season. In the cold season, daytime and nighttime warming effects drove the net effect of forests; (3) the effects of forests on temperatures were mainly negatively correlated with the background temperatures in Europe. Under extreme climate conditions, the cooling effect of forests will be stronger during heatwaves or weaker during cold spring seasons; (4) the background temperature affects the spatiotemporal distribution of differences in albedo and evapotranspiration (forest minus open land), which determines the spatial, seasonal and interannual effects of forests on temperature. The extrapolation of the results could contribute not only to model validation and development but also to appropriate land use policies for future decades under the background of global warming.

“…Despite the fact that deforestation has been recognized as an important driver of local climate change (Davin and de Noblet-Ducoudré, 2010;Bonan, 2008), its effect on heatwaves is still poorly understood. Until now it has been unclear whether forests reach higher or lower temperatures than grassland during warm summer conditions or heatwaves (Zaitchik et al, 2006;Teuling et al, 2010;Anderson et al, 2010). One of the major open questions is how and to what extent land-use affects temperature extremes during heatwaves.…”

Abstract. This study investigates the difference in land-atmosphere interactions between grassland and forest during typical heatwave conditions in order to understand the controversial results of Teuling et al. (2010) (hereafter T10), who found the systematic occurrence of higher sensible heat fluxes over forest than over grassland during heatwaves. With a simple but accurate coupled land-atmosphere model, we show that existing parametrizations are able to reproduce the findings of T10 for normal summer and heatwave conditions. Furthermore, we demonstrate the sensitivity of the coupled system to changes in incoming radiation and early-morning temperature typical for European heatwaves.Our results suggest that the fast atmospheric control of stomatal resistance can explain the observed differences between grassland and forest. The atmospheric boundary layer has a buffering function therein: increases in stomatal resistance are largely compensated for by increases in the potential evaporation due to atmospheric warming and drying.In order to disentangle the contributions of differences in several static and dynamic properties between forest and grassland, we have performed a virtual experiment with artificial land-use types that are equal to grassland, but with one of its properties replaced by that of forest. From these, we confirm the important role of the fast physiological processes that lead to the closure of stomata. Nonetheless, for a full explanation of T10's results, the other properties (albedo, roughness and the ratio of minimum stomatal resistance to leaf-area index) play an important but indirect role; their influences mainly consist of strengthening the feedback that leads to the closure of the stomata by providing more energy that can be converted into sensible heat. The model experiment also confirms that, in line with the larger sensible heat flux, higher atmospheric temperatures occur over forest.As our parametrization for stomatal resistance is empirical rather than mechanical, our study stresses the demand for a better mechanistic understanding of physiological processes in plants.
