Abstract Because of the scarcity meteorological observations, precipitation climate on Tibetan Plateau and surrounding regions (TP) has been insufficiently documented so far. In this study, characteristics basic features TP during an 11-yr period (2001–11) are described monthly-to-annual time scales. For purpose, a new high-resolution atmospheric dataset is analyzed, High Asia Reanalysis (HAR), generated by dynamical downscaling global analysis data using Weather Research Forecasting (WRF)...
Abstract. The western Nyainqentanglha Range is located in the south-eastern centre of Tibetan Plateau. Its north-western slopes drain into Lake Nam Co. region special interest for glacio-climatological research as it influenced by both continental climate Central Asia and Indian Monsoon system, situated at transition zone between temperate subcontinental glaciers. A glacier inventory whole mountain range was generated year around 2001 using automated remote sensing GIS techniques based on...
Abstract The High Asia Refined analysis (HAR) is a regional atmospheric data set generated by dynamical downscaling of the Final operational global (FNL) using Weather Research and Forecasting (WRF) model. It has been successfully widely utilized. A new version (HAR v2) with longer temporal coverage extended domains currently under development. ERA5 reanalysis used as forcing data. This study aims to find optimal set‐up for production HAR v2 provide similar or even better accuracy HAR....

The measures taken to contain the spread of COVID-19 in 2020 included restrictions people's mobility and reductions economic activities. These drastic changes daily life, enforced through national lockdowns, led abrupt anthropogenic CO2 emissions urbanized areas all over world. To examine effect social on local CO2, we analysed district level fluxes measured by eddy-covariance technique from 13 stations 11 European cities. data span several years before pandemic until October (six months...
Abstract. Meteorological observations over the Tibetan Plateau (TiP) are scarce, and precipitation estimations this remote region difficult. The constantly improving capabilities of numerical weather prediction (NWP) models offer opportunity to reduce problem by providing fields other meteorological variables high spatial temporal resolution. Longer time periods years decades can be simulated NWP successive model runs shorter periods, which described term "regional atmospheric reanalysis"....
Abstract. Determinations of glacier-wide mass and energy balance are still scarce for the remote mountains Tibetan Plateau, where field measurements challenging. Here we run evaluate a physical, distributed model Zhadang Glacier (central Tibet, 30° N) based on in-situ over 2009–2011 an uncertainty estimate by Monte Carlo ensemble strategies. The application aims to provide first quantification how Indian Summer Monsoon (ISM) impacts entire glacier various stages monsoon's annual cycle. We...

A one-year data set for the year 2015 of near-surface air temperature (T ), crowdsourced from 'Netatmo' citizen weather stations (CWS) in Berlin, Germany, and surroundings was analysed.The CWS set, which has been quality-checked filtered a previous study, consists T measurements several hundred CWS.It investigated (1) how are distributed among urban rural environments, as represented by 'local climate zones' (LCZ), (2) LCZ characterised along annual cycle concerning intra-LCZ variability,...
Abstract Climate variables that control the annual cycle of surface energy and mass balance on Zhadang glacier in central Tibetan Plateau were examined over a 2 year period using physically based energy-balance model forced by routine meteorological data. The modelled results agree with measured values albedo, incoming longwave radiation, temperature level glacier. For whole observation period, radiation component dominated (82%) total heat fluxes. This was followed turbulent sensible (10%)...
Abstract. The Tibetan Plateau (TP) is the origin of many large Asian rivers, which provide water resources for regions in south and east Asia. Therefore, cycle on TP adjacent high mountain ranges, particular precipitation distribution variability play an important role availability billions people downstream TP. High Asia Refined analysis (HAR) used to analyse dynamical factors that influence region, including resulting enhancement suppression precipitation. Four fields can are considered:...
Abstract. The traditional approach to simulations of alpine glacier mass balance (MB) has been one-way, or offline, thus precluding feedbacks from changing surface conditions on the atmospheric forcing. In addition, glaciers have only simply, if at all, represented in models date. Here, we extend a recently presented, novel technique for simulating glacier–atmosphere interactions without need statistical downscaling, through use coupled high-resolution mesoscale and physically-based climatic...

Abstract Complex topography significantly modifies radiation fluxes at the earth’s surface. As spatial resolutions of mesoscale weather forecast models increase, terrain effects on induced by slope aspect, angle, sky view factor, and shadowing also gain importance. A parameterization scheme is hence designed to better represent these topographic influences improve forecasts. The grid- subgrid-scale allows computation for each model grid cell considering arbitrarily fine resolved without...
