The performance of gridded precipitation products is especially important over mountainous regions because the lack observations. This study provides a detailed evaluation spatial patterns presented by ERA-Interim, ERA5, ERA5-Land, and refined HAR datasets with resolutions from coarse to fine (0.7°, 0.25°, 0.1°, respectively) southern slope central Himalaya, Nepal. major findings are as follows: (1) high-resolution ERA5-Land ERA5 well present observed pattern but generally overestimated...
Abstract. Reliable precipitation data are highly necessary for geoscience research in the Third Pole (TP) region but still lacking, due to complex terrain and high spatial variability of here. Accordingly, this study produces a long-term (1979–2020) high-resolution (1/30∘, daily) dataset (TPHiPr) TP by merging atmospheric simulation-based ERA5_CNN with gauge observations from more than 9000 rain gauges, using climatologically aided interpolation random forest methods. Validation shows that...
Abstract Solid water resources such as glaciers and snow cover are widely distributed in the western Tibetan plateau (WTP), precipitation is key supply of them. However, characteristics over WTP remain unclear due to sparse observations. Using observation‐based gridded data (APHRODITE, GPCC), satellite products (TRMM, GPM), reanalysis (ERA5, ERA‐Interim, JRA‐55) weather research forecasting model (WRF)‐simulation (HAR10, HAR30), this study investigated high mountain areas (altitude >2,500...
The Global Precipitation Measurement (GPM) mission provides high-resolution precipitation estimates globally. However, their accuracy needs to be accessed for algorithm enhancement and hydro-meteorological applications. This study applies data from 388 gauges in Nepal evaluate the spatial-temporal patterns presented recently-developed GPM-Era satellite-based (SBP) products, i.e., Integrated Multi-satellite Retrievals GPM (IMERG), satellite-only (IMERG-UC), gauge-calibrated IMERG (IMERG-C),...
Around 70 Mha of land cover changes (LCCs) occurred in Europe from 1992 to 2015. Despite LCCs being an important driver regional climate variations, their temperature effects at a continental scale have not yet been assessed. Here, we integrate maps historical with model investigate air and humidity effects. We find average change -0.12 ± 0.20 °C, widespread cooling (up -1.0 °C) western central summer spring. At scale, the mean is mainly correlated agriculture abandonment (cropland-to-forest...
Nepal is a mountainous country located on the southern slope of central Himalayas, where ~3% total annual rainfall occurs in winter season. The inter-annual variability and shift precipitation are great importance space time, however, has not been investigated Nepal. This study sought to investigate (DJF), below- above-average anomalies over their controlling factors associated with ocean-atmospheric circulation patterns during historical period 1987–2015. Here, we used Asian...
Abstract. Subseasonal-to-seasonal (S2S) prediction, especially the prediction of extreme hydroclimate events such as droughts and floods, is not only scientifically challenging, but also has substantial societal impacts. Motivated by preliminary studies, Global Energy Water Exchanges (GEWEX)/Global Atmospheric System Study (GASS) launched a new initiative called “Impact Initialized Land Surface Temperature Snowpack on Subseasonal to Seasonal Prediction” (LS4P) first international grass-roots...
Satellite precipitation products can provide alternative data in remote areas with sparse surface observations, but the performance of these must be evaluated before hydrometeorological applications. The western Tibetan Plateau (WTP) covers an area nearly 1,500,000 km2, where China Meteorological Administration stations are very due to harsh natural environment. Therefore, previous evaluations satellite have resulted a gap on WTP. In this study, hourly collected from 29 newly established...
We present the first direct measurements of terahertz atmospheric transmission above Dome A, highest point on Antarctic plateau at an elevation 4.1 km. The best-quartile during Austral winter is 80% a frequency 661 GHz (453 μm), corresponding to precipitable water vapor column 0.1 mm. Daily averages as low 0.025 mm were observed. atmosphere very stable, and excellent observing conditions generally persist for many days time. exceptional over high open new far-infrared spectral windows...
Abstract While the Himalayas act as a natural barrier to water vapor transport Tibetan Plateau, many north‐south‐oriented valleys channel moisture onto Plateau. However, owing lack of in situ data, spatiotemporal characteristics precipitation remain unclear along these valleys. In this study, high‐altitude (2,800–4,500 m above mean sea level) rain‐gauge network was established Yadong Valley, one main central Himalayan Region (CHR). New observations from are used evaluate Integrated...
Abstract Ground observation of precipitation over complex terrain is subject to large uncertainties due inadequate sampling. This study explores a method that combines limited gauge data and high‐resolution numerical simulation quantify the in central Himalaya. Specifically, Coefficient spatial Variability (CV) minimum Number Required Stations (NRS) obtain areal‐mean ground truth values within 0.25° area are investigated using fine‐scale meteorological at 1.5 km grid spacing. Evaluation...
Abstract The alpine lakes widely distributed over the Tibetan Plateau (TP) are not only highly sensitive to climate but also regulate regional climate. However, lack of TP lake observations limits understanding lake‐atmosphere interactions. Here, we show relative importance parameterizing surface and internal thermal processes in describing energy budget Based on situ at Lake Nam Co, a large deep TP, employed coupled Weather Research Forecasting with (WRF‐Lake) model clarify their roles....
Abstract Weather Research and Forecasting (WRF) simulations with different selections of subgrid orographic drag over the Tibetan Plateau have been evaluated observation ERA‐Interim reanalysis. Results show that schemes, especially turbulent form (TOFD) scheme, efficiently reduce 10 m wind speed bias RMS error respect to station measurements. With combination gravity wave, flow blocking TOFD is simulated more realistically than individual schemes only. Improvements are also seen in 2 air...
Abstract Current regional and global climate models often have significant cold wet biases in the simulation of for Southern Tibetan Plateau (STP). This region has complex terrain steep slopes, underlying surface many areas is stony with little soil vegetation, which causes negligible infiltration rapid runoff. The default type (loam) Weather Research Forecasting (WRF) thus replaced bedrock to improve representation mountainous hydrological processes this region. domain identified by using...
