“…Variability in precipitation is due to topographic (orientation, elevation, and slope of the mountains) and climatic (prevailing wind, distance from the sea) influences, altered by the moist air that get blocked by the mountains [8,9]. In fact, several studies in the northern Andes [10][11][12] have shown extreme spatio-temporal rainfall variability.…”

Abstract:A laser-optical disdrometer served as reference to assess the absolute percent bias of calculated rainfall intensity using the data of different-resolution tipping-bucket rain gauges classically applied by climatologists and hydrologists in the Andean region. Additionally, the impact of the calculation method (tip counting versus cubic spline interpolation) was examined. The combined effect was assessed for different rainfall intensity classes (0-0.99, 1-1.99, 2-4.99, and 5-10 mm·h −1 ) and timescales (5, 10, 30, and 60 min). Additionally, the variation in percent absolute bias of the Davis rain gauge, the collector most widely used in the study region, was defined with respect to the Texas rain gauge along an elevation gradient between 3300 and 4000 m a.s.l. Results reveal that the value of the percent absolute bias is largest for small rainfall intensities (≤2 mm·h −1 ) and short timescales (≤10 min), and decreases when the cubic spline interpolation is used. No relation was found between the error, the elevation, and rainfall depth along the gradient. Based on the research findings, it is recommended to measure precipitation in the high Andean mountain region with a high-resolution sensor and to consider cubic spline for the computation of intensities.

Status of fish assemblage structure in the Ganga and Indus riverine systems of the western Himalaya

et al. 2023

The Ganga and Indus riverine systems are the major freshwater resources in the western Himalaya. The aim of this review was to critically analyze the status of inland fisheries in both the Ganga and Indus Riverine systems of the western Himalaya. Data from secondary sources such as research publications, scientific documents, technical advisories, and books were retrieved. The fish diversity of both riverine systems reveals that the number of endemic and native species like Tor tor, Tor putitora, Glyptothorax spp., Nemacheilus spp., and Schizothorax richardsonii is decreasing. Moreover, in most of the rivers of both riverine systems, exotic species, especially those belonging to the Cyprinidae family, for example, Cyprinus carpio, are increasing and are also dominant, followed by the families Cobitidae and Sisoridae. The Ganga and Indus riverine systems' diverse fish populations have declined because of various anthropogenic activities, especially water pollution and dam construction, which are responsible for the change in river hydrology. Frequent data were available on the Ganga riverine system, which shows a continuous decline in fish diversity. A similar trend was observed in the lower stretches of the Indus riverine system. But negligible information was available on the upper stretches of the Indus riverine system; this may be due to a large research gap. However, adequate knowledge of both river systems is necessary to develop conservation and management strategies for the sustainable development of fishery resources in India in the future.

“…Mountain precipitation, much of which is stored as glaciers and seasonal snowpack and released through melting, is an important contributor to the flow of the largest rivers in this region [3][4][5]. Despite the importance of precipitation in HMA as a water resource, the complex terrain of HMA, combined with the sparse distribution of weather stations and significant contribution of snow-type precipitation at upper elevations, makes precipitation characterization in this region very challenging [6][7][8][9].…”

Characteristics of Historical Precipitation in High Mountain Asia Based on a 15-Year High Resolution Dynamical Downscaling

et al. 2021

The mountains of High Mountain Asia serve as an important source of water for roughly one billion people living downstream. This research uses 15 years of dynamically downscaled precipitation produced by the Weather Research and Forecasting (WRF) model to delineate contrasts in precipitation characteristics and events between regions dominated by the Indian Summer Monsoon (ISM) versus westerly disturbances during the cool season (December to March). Cluster analysis reveals a more complex spatial pattern than indicated by some previous studies and illustrates the increasing importance of westerly disturbances at higher elevations. Although prior research suggests that a small number of westerly disturbances dominate precipitation in the western Himalaya and Karakoram, the WRF-downscaled precipitation is less dominated by infrequent large events. Integrated vapor transport (IVT) and precipitation are tightly coupled in both regions during the cool season, with precipitation maximizing for IVT from the south-southwest over the Karakoram and southeast-southwest over the western Himalaya. During the ISM, Karakoram precipitation is not strongly related to IVT direction, whereas over the western Himalaya, primary and secondary precipitation maxima occur for flow from the west-southwest and northwest, respectively. These differences in the drivers and timing of precipitation have implications for hydrology, glacier mass balance, snow accumulation, and their sensitivity to climate variability and change.
