Abstract: A high-altitude project of the RIHN established an automatic weather station (AWS) at Domkhar (76.82E, 34.45N, 3808m) in Ladakh in June 2009. The AWS captured rainfall events in early August that caused flooding and mudslides in Ladakh. At the conference, we present 1)general meteorological features observed by the AWS, 2)time series of rainfall in early August, and 3) synoptic/continental scale circulation fields associated with 1) and 2). There was flooding in Ladakh from 4 to 8 August. Our rain gauges in Leh and the AWS recorded mid-night rainfall for this period. The hourly rainfall at the peak time (0:13 – 1:13AM of 6th ) in western and northern Leh were 15 and 7 mm/hr, respectively. They are not that much greater than rainfall reported in a local newspaper. Large differences between the two summers were found in pentad 34 (5–9 June) and pentad 44 (4–8 August). In pentad 44, the precipitation, north–south wind and humidity differed for 2009 and 2010, with there being flooding in 2010. From 4 to 8 August of 2010, at 500 hPa level, moist air from the south are observed over Afghanistan, north Pakistan, and the western part of the Tibetan Plateau.
