Abstract The objective of this study is to evaluate two satellite rainfall products Global Precipitation Measurement Integrated MultisatellitE Retrievals and Tropical Rainfall Measuring Mission 3B42V7 (GPM IMERG TRMM 3B42V7) in southern Tibetan Plateau region, with special focus on the dependence products' performance topography intensity. Over 500 situ rain gauges constitute an unprecedentedly dense gauge network over region provide exceptional resource for ground validation estimates. Our...
Risk management has reduced vulnerability to floods and droughts globally1,2, yet their impacts are still increasing3. An improved understanding of the causes changing is therefore needed, but been hampered by a lack empirical data4,5. On basis global dataset 45 pairs events that occurred within same area, we show risk generally reduces faces difficulties in reducing unprecedented magnitude not previously experienced. If second event was much more hazardous than first, its impact almost...
Heat waves (HWs) are projected to become more frequent and last longer over most land areas in the late 21st century, which raises serious public health concerns. Urban residents face higher risks due synergies between HWs urban heat islands (UHIs) (i.e., UHIs under HW conditions). However, responses of rural surface energy budgets still largely unknown. This study analyzes observations from two flux towers Beijing, China reveals significant differences (cropland) ecosystems HWs. It is found...
Previous projections show consistent increases in river flows of Asian Water Towers under future climate change. Here we find non-monotonic changes for seven major rivers originating from the Tibetan Plateau at warming levels 1.5 °C, 2.0 and 3.0 °C based on an observation-constrained hydrological model. The annual mean streamflow level decreases by 0.1-3.2% relative to present-day condition, 1.5-12% level. shifting Yellow, Yangtze, Brahmaputra, Ganges are mostly influenced projected...
Abstract Growing urban population and the distinct strategies to accommodate them lead diverse development patterns worldwide. While local evidence suggests presence of signatures in rainfall anomalies, there is limited understanding how responds divergent Here we unveil a divergence exposure extreme for 1790 inland cities globally, attributable their respective patterns. Cities that experience compact tend witness larger increases frequency over downtown than rural surroundings, while...
Abstract We examine the upper tail of flood peak distributions through analyses annual observations from more than 8,000 U.S. Geological Survey (USGS) stream gaging stations and hydrometeorological storms that produce most extreme floods. focus on distribution ratio , which is defined as discharge for record at a station divided by sample 10‐year magnitude. The 14 June 1903 Heppner storm, produced an 200, was product hailstorm formed along Blue Mountains in eastern Oregon, region dominated...
Abstract This study investigates the dependency of evaluation Integrated Multisatellite Retrievals for Global Precipitation Measurement (IMERG) rainfall product on gauge density a ground-based rain network as well intensity over five subregions in mainland China. High-density gauges (1.5 per 100 km2) provide exceptional resources ground validation satellite estimates this region. Eight different networks were derived with contrasting densities ranging from 0.04 to 4 km2. The focuses two warm...
Abstract The climatology of summer heavy rainfall events over the Beijing metropolitan region during 2008–2012 is investigated with aid an observational network rain gauges and Weather Research Forecasting model. Two “hot spots” higher frequency are observed. One located urban core other resides in climatological downwind region. comparative sets model runs designed to assess effect land surface properties without presence city on simulation results. By comparing two runs, changes...
This study investigated impacts of urban forms on the future thermal environment over Beijing, capital city China. Beijing is experiencing remarkable expansion and planned to undergo transformation from single-centric (compact-city) poly-centric (dispersed-city). Impacts were compared evaluated by conducting numerical experiments based a regional atmospheric model coupled with single-layer canopy as well climate forcing output global model. Results show that dispersed efficient in reducing...
Abstract Hydrometeorological impacts due to urbanization for cities close complex terrain are poorly understood the complexities of terrain‐related circulation and urban perturbations atmospheric flow. In this study, we examine on extreme monsoon rainfall resultant flooding over central Arizona based high‐resolution hydrological model simulations. Strong positive anomalies at urban‐rural interface downwind city mainly related dynamic effects (increased surface roughness) convective outflow...
Nurse plants are those that facilitate the growth and development of other plant species (target species) beneath their canopy because they offer benign microhabitats more favorable for seed germination and/or seedling recruitment than surrounding environment. have been mainly used to restore vegetation in arid sub-arid zones recent years. Based on summarizing definition nurse target plant, we review nursing effect mechanisms, ecological factors influence effect, relationships between...
Abstract In this study, observational and numerical modeling analyses based on the Weather Research Forecasting Model (WRF) are used to investigate impact of urbanization heavy rainfall over Milwaukee–Lake Michigan region. The authors examine urban modification for a storm system with continental-scale moisture transport, strong large-scale forcing, extreme large area upper Midwest United States. WRF simulations were carried out sensitivity distribution in around different land surface model...

Abstract We analyze flash flooding in small urban watersheds, with special focus on the roles of rainfall variability, antecedent soil moisture, and storm water management infrastructure event hydrologic response. Our results are based empirical analyses high‐resolution discharge observations over Harry's Brook watershed Princeton, New Jersey, during 2005–2006, as well numerical experiments Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model. two subwatersheds Brook, a 1.1 km 2...
Abstract The August 1975 flood in central China was one of the most destructive floods history. Catastrophic flooding product extreme rainfall from Typhoon Nina over a 3-day period 5 to 7 1975. Despite prominence flood, relatively little is known about evolution responsible for flood. Details and event are examined based on empirical analyses streamflow measurements downscaling simulations using Weather Research Forecasting (WRF) Model, driven by Twentieth Century Reanalysis (20CR) fields....
Abstract River regulations and changing land management practices are generally perceived to be the dominant drivers of river flood changes in countries with rapid economic growth, such as China. Here, we demonstrate based on most comprehensive database date, that climate variations dominate spatial pattern annual peak discharge China, despite intense human alterations systems over past four decades. Regional increases mainly associated increasing precipitation due East Asian Summer Monsoon,...
