Reliable quantification of urban heat island (UHI) can contribute to the effective evaluation potential risk. Traditional methods for UHI intensity (UHII) using pairs-measurements are sensitive choice stations or grids. In order get rid limitation urban/rural divisions, this paper proposes a new approach quantify surface UHII (SUHII) relationship between MODIS land temperature (LST) and impervious areas (ISA). Given footprint LST measurement, ISA was regionalized include information...
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....
Precipitation is a central quantity of hydrometeorological research and applications. Especially in complex terrain, such as High Mountain Asia (HMA), surface precipitation observations are scarce. Gridded products one way to overcome the limitations ground truth observations. They can provide datasets continuous both space time. However, there many available, which use various methods for data generation lead different values. In our study we compare nine gridded from origins (ERA5,...
Abstract The Tibetan Plateau (TP) is often called the “Water Tower of Asia,” which contains largest amount snow and glaciers outside polar regions. As an important variable feature land surface, coverage on TP has great impacts regional climate. However, commonly used ERA5 reanalysis in dynamical downscaling largely overestimates depth for TP. To improve representation cover ERA5, a new ERA5‐driven data set (High Asia Refined analysis version 2, HAR v2) was generated by Weather Research...
Abstract The hydroclimate of the Tibetan Plateau (TP) and Central Asia (CA) plays a crucial role in sustaining surface water reservoirs thus resources respective regions. In this study, we investigate changes Asian its driving forces during specific time intervals last 3 Ma. We conduct high‐resolution (∼0.75° per grid cell) general circulation model ECHAM‐5 experiments with boundary conditions for mid‐Pliocene (∼3 Ma), Last Glacial Maximum (LGM; ∼21 ka), mid‐Holocene (∼6 pre‐industrial....
Abstract. Landslide is a major natural hazard in Kyrgyzstan and Tajikistan. Knowledge about atmospheric triggering conditions climatic disposition of landslides Tajikistan limited even though this topic has already been investigated thoroughly other parts the world. In study, newly developed, high-resolution High Asia Refined analysis version 2 (HAR v2) data set generated by dynamical downscaling was combined with historical landslide inventories to analyze that initialized The results...
The construction of multifunction reservoirs is important for flood control, agriculture irrigation, navigation, and hydropower generation, but dam will inevitably affect the downstream flow sediment regimes, which can cause some environmental ecological consequences. Therefore, this paper aims to propose a framework assessing multiobjective reservoir operation model based on flows sustaining suspended concentration (SSC) requirements in turbidity maximum zone (TMZ). Yangtze River Estuary...
Abstract The Qaidam Basin (QB) in the northeastern Tibetan Plateau held a megalake system during Pliocene. Today, lower elevations basin are hyperarid. To understand to what extent climate plays role maintenance of Pliocene, we applied Weather Research and Forecasting model for dynamical downscaling ECHAM5 global simulations present day mid‐Pliocene. When imposing mid‐Pliocene on QB with its modern land surface settings, annual water balance ( ), that is, change terrestrial storage within...
The Central European Refined analysis (CER) was developed in 2016 as a high-resolution, reanalysis-based, gridded dataset for Europe. second version (CER v2) aims to further improve the performance of CER with particular focus on precipitation data metropolitan region Berlin-Brandenburg. simulation setup consists two-way nested, cascaded domains Germany (10 km grid spacing) and Berlin-Brandenburg (2 employs daily re-initialization approach. Major changes from precursor include use ECMWF-ERA5...

<p>Climatic-triggered natural hazards such as landslides and glacier lake outburst floods pose a threat to human lives in the third pole region. Availability of accurate climate data with high spatial temporal resolution is crucial for better understanding climatic triggering mechanisms these localized hazards. Within framework project “Climatic Tectonic Natural Hazard Central Asia” (CaTeNA), High Asia Refined analysis version 2 (HAR v2) under...
The Qaidam Basin (QB) in the northeastern Tibetan Plateau held a mega-lake system during Pliocene. Today, lower elevations basin are hyperarid. To understand mechanisms behind this change, we applied Weather Research and Forecasting model for dynamical downscaling of ECHAM5 global climate simulations present-day (PD) mid-Pliocene (PLIO) conditions. In PLIO, annual water balance (∆S) QB is higher than that PD, resulting from stronger moisture influx across western border winter, spring,...
<p>In the Pliocene, Qaidam Basin in northeastern Tibetan Plateau contained a freshwater mega-lake system. The lake system disappeared and lower parts of basin now feature hyperarid conditions. What led to collapse could it appear again future? Understanding sensitivity basin’s water balance changes atmospheric conditions is crucial for answering this question. We employed Weather Research Forecasting model dynamical downscaling two time slices. These were...
