Trends in Daily Climatic Extremes of Temperature and Precipitation in Nepal
Using RClimDex, this paper analyzed daily temperature data for 36 years (1971 to 2006) and precipitation data for 46 years (1961-2006) of Nepal. General increasing trend has been observed in temperature extremes. Findings suggest complex processes in precipitation extremes but at the same time there is indication that more weather related extreme events like floods and landslides can be expected in future.
DENDROCLIMATIC SIGNALS IN LONG TREE-RING CHRONOLOGIES FROM THE HIMALAYAS OF NEPAL
We describe the development of a tree-ring chronology network in Nepal that is suitable for reconstructing temperature-related climate forcing over the past few hundred years. The network is composed of 32 tree-ring chronologies and is represented by five indigenous tree species. An empirical orthogonal function analysis of the chronologies over the common interval 1796–92 indicates the existence of coherent large-scale signals among the tree-ring chronologies that are hypothesized to reflect, in part, broad-scale climate forcing related to temperatures.
Treeline dynamics with climate change at the central Nepal Himalaya
Treeline shifting in tandem with climate change has widely been reported from various parts of the world. In Nepal, several impacts of climate change on thephysical environment have been observed, but study on the biological impacts is lacking. This dendrochronological study was carried out at the treeline in the high mountain slope of Kalchuman Lake (3750–4003ma.s.l.) area of Manaslu Conservation Area in the central Nepal Himalaya to explore the impact of climate change on the treeline dynamic.
