Alpine Grassland Reviving Response to Seasonal Snow Cover on the Tibetan Plateau

چکیده
Season snow cover plays an important role in vegetation growth alpine regions. In this study, we analyzed the spatial and temporal variations seasonal start of growing season (SOS) grasslands preliminarily studied mechanism by which affects SOS changes modifying soil temperature (ST) moisture (SM) spring. The results showed that significant interannual trends SOS, end date (SED), days (SCD), ST, SM existed over Tibetan Plateau (TP) China from 2000 to 2020. advanced 2.0 d/10 a TP period. Moreover, advancing eastern central parts delayed trend west. SED SCD exhibited decreasing high-elevation areas, respectively, opposite low-elevation areas. ST areas increasing tended increase most effects on indirectly influenced grasslands. SEDs more observed herein could provide increasingly wet conditions optimal for advancement while less shorter seasons delay TP.

MODIS/Terra observed seasonal variations of snow cover over the Tibetan Plateau
[1] Seasonal variations of snow cover fraction (SFC) over the Tibet Plateau (TP) are examined using the data acquired from the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra spacecraft. In this study, we first evaluate the accuracy of the MODIS high-resolution snow cover data by comparing the data with in-situ Chinese snow observations. Results show that overall accuracy of ...
متن کاملSpatio-Temporal Change of Snow Cover and Its Response to Climate over the Tibetan Plateau Based on an Improved Daily Cloud-Free Snow Cover Product
Using new, daily cloud-free snow-cover products, this study examines snow cover dynamics and their response to climate change. The results demonstrate that the daily cloud-free snow-cover products not only posses the advantages of the AMSR-E (unaffected by weather conditions) and MODIS (relatively higher resolution) products, but are also characterized by high snow and overall classification ac...
متن کاملSeasonal and Inter-Annual Variations in Carbon Dioxide Exchange over an Alpine Grassland in the Eastern Qinghai-Tibetan Plateau
This work analyzed carbon dioxide exchange and its controlling factors over an alpine grassland on the eastern Qinghai-Tibetan Plateau. The main results show that air temperature and photosynthetically active radiation are two dominant factors controlling daily gross primary production. Soil temperature and soil water content are the main factors controlling ecosystem respiration. Canopy photos...
متن کاملObject-Based Detection of Lakes Prone to Seasonal Ice Cover on the Tibetan Plateau
The Tibetan Plateau, the world’s largest orogenic plateau, hosts thousands of lakes that play prominent roles as water resources, environmental archives, and sources of natural hazards such as glacier lake outburst floods. Previous studies have reported that the size of lakes on the Tibetan Plateau has changed rapidly in recent years, possibly because of atmospheric warming. Tracking these chan...
متن کاملInfluence of the Madden–Julian oscillation on Tibetan Plateau snow cover at the intraseasonal time-scale
The Tibetan Plateau (TP), known as the third pole of the Earth, has snow cover with intraseasonal to decadal variability that affects weather and climate both inside and outside the TP. However, the factors that generate the TP snow cover (TPSC) anomalies at the intraseasonal time-scale are unclear. This report reveals the influence of the Madden‒Julian oscillation (MJO), which is the most domi...
