Impact of forest degradation on streamflow regime and runoff response to rainfall in the Garhwal Himalaya, Northwest India

“…The authors did not offer any firm conclusion as to the main reasons for this regionally observed decline, but suggested a combination of cooling of the atmosphere by largescale irrigation in the Gangetic plain and increased occurrence of anthropogenic aerosols as being potentially important factors. However, rainfall at Dehradun has exhibited an increasing trend since the 1930s, while rainfall at Mussoorie station has shown no significant long-term change (Basistha et al 2009). Somewhat surprisingly, no significant difference was found for rainfall amounts measured at 1700 and 1900 m a.m.s.l., at both Arnigad and Bansigad (N. Q. Qazi and S.P.…”

“…According to Figure 9, rainfall in 2009/10 was low both during the main monsoon season and during winter, while the monsoons of both 2008/09 and, especially, 2010/11 were wetter than normal. Pertinently, according to Basistha et al (2009) rainfall in the southern part of the Lesser Indian Himalaya (in which Mussoorie and the study catchments are located) and in the adjacent Siwalik Hills began to decline around the mid-1960s, in terms of annual totals as well as amounts received during the monsoon. The authors did not offer any firm conclusion as to the main reasons for this regionally observed decline, but suggested a combination of cooling of the atmosphere by largescale irrigation in the Gangetic plain and increased occurrence of anthropogenic aerosols as being potentially important factors.…”

A method for including daily patterns to synthetic wind speed data for energy systems planning: Validation in the Azores Islands

“…The resulting four representative wind patterns in this case are highly dominated ($90%) by one of the patterns, which is likely to give results very similar to using one "typical day." Jiménez et al 21 used spatial and temporal similarity methods to identify local wind patterns in the Iberian Peninsula yielding six robust wind patterns. These methods are suitable for wind characterisation for climatological purposes, but not necessarily adequate when a clear relation between temporal wind power availability and demand patterns is sought.…”
