Peer review report 1 On “Discriminating types of precipitation in Qilian Mountains, Tibetan Plateau”
1. Original Submission 1.1. Recommendation Major Revision 2. Comments to Author: Comments on “Precipitation type discrimination in a mountainous region and corresponding meteorological conditions over different precipitation types, a case study from the Qilian Mountainous at eastern edge of the Tibetan Plateau” by Junfeng Liu. Precipitation types have great impacts on the hydrological cycle, energy balance and the accuracy of observations. The discrimination of the precipitation types mainly relies on empirical relationships derived from surface air conditions or other atmospheric conditions. In the paper, rain/snow boundary observed by time-lapse photography and the automatic meteorological observation data at different altitudes were used for the identification of precipitation types at outlet of the Hulugou River Basin of the Qilian Mountains. The new method greatly improved the observing capabilities of precipitation type in regional scale. For this reason I think the paper can be accepted after moderate revisions. There are three minor comments as following: 1. In the study, it requires more evidence to describe how to determine the precipitation type based on the observation of rain/snow boundary by time-lapse photography. In addition to surface air conditions, the surface temperature has a great impact on the boundary. 2. The results in the manuscript indicate that the air temperature threshold range of precipitation type fluctuated widely. I think the reason is that the rain/snow boundary is a transition zone. The areas and surface conditions of the zone have direct impact on the boundary. 3. The authors should carefully check and improve the English used in the paper.
