10.1 Climatic Setting (M. Walther)
Climate and Hydrological Development and Conditions between 1983 and 2005 in the
Drainage Basin of Buyant Gol
The climate and hydrological data have been collected by the Meteorological and
Hydrological Station of Khovd branch of the Agricultural University of Mongolia. Climate
data are measured directly beside the station, whereas the hydrological data are taken from
three different stations along Buyant Gol during three measuring periods (1967 -1992 10 km
upstream of Jargalant, 1993 -1997 5 km upstream of Jargalant and since 1998 a few 100 m
upstream of the Buyant Gol Bridge in Jargalant).
Precipitation between 1983 and 2005
Based on the data of the Meteorological and Hydrological Station of Khovd Branch Institute
of the Agricultural University of Mongolia it is possible to analyze the period between 1983
and 2005. According to Fig.14 June and July precipitation has decreases, whereas the figures
for August show an increase of monthly averages. The mean annual precipitation calculated
for the period between 1983 and 2005 is 132 mm (Fig.15) and shows a negative trend of
decreasing precipitation. Especially between 1996 and 2002 a very dry period is visible
