Weak precipitation, warm winters and springs impact glaciers of south slopes of Mt. Everest (central Himalaya) in the last 2 decades (1994–2013)
Franco Salerno,Nicolas Guyennon,Sudeep Thakuri,Gaetano Viviano,Emanuele Romano,Elisa Vuillermoz,Paolo Cristofanelli,P. Stocchi,G. Agrillo,Yaoming Ma,Gianni Tartari +10 more
TL;DR: In this article, the authors explore the southern slopes of Mt Everest, analyzing the time series of temperature and precipitation reconstructed from seven stations located between 2660 and 5600 m asl during 1994-2013, complemented with the data from all existing ground weather stations located on both sides of the mountain range (Koshi Basin) over the same period.

TL;DR: This study develops and assess a one-dimensional lake model and applies it to 32 lakes from a global observatory network and provides guidance to where the general model approach and associated assumptions work, and cases where adjustments to model parameterisations and/or structure are required.
Journal ArticleDOI
Factors controlling the accelerated expansion of Imja Lake, Mount Everest region, Nepal
TL;DR: In this paper, the authors explored the link between area increase of Imja Tsho (Lake) and changes of the Imja Glacier (area ~25km2) under the influence of climate change using multitemporal satellite imagery and local climate data.
Journal ArticleDOI
Coupling high-resolution measurements to a three-dimensional lake model to assess the spatial and temporal dynamics of the cyanobacterium Planktothrix rubescens in a medium-sized lake
Elisa Carraro,Nicolas Guyennon,David P. Hamilton,Lucia Valsecchi,Emanuela Chiara Manfredi,Gaetano Viviano,Franco Salerno,Gianni Tartari,Diego Copetti +8 more
TL;DR: In a medium-sized pre-alpine lake (North Italy) the cyanobacterium Planktothrix rubescens has strongly dominated the phytoplankton assemblage since 2000 as discussed by the authors.
Journal ArticleDOI
Elevation-dependent warming of maximum air temperature in Nepal during 1976–2015
Sudeep Thakuri,Suchana Dahal,Dibas Shrestha,Nicolas Guyennon,Emanuele Romano,Nicola Colombo,Franco Salerno +6 more
TL;DR: Significant elevation-dependent warming of near-surface air temperature and diurnal temperature range (DTR) has been observed in Nepal (southern central Himalaya) until 2566 m.a.s.l. as mentioned in this paper.
