Abstract Numerous studies have evaluated the reliability and hydrologic utility of various rainfall data sets through hydrological modeling. However, calibration models compensates for errors in inputs. The drivers, conditions, factors affecting given accuracy inputs are not well understood. Here, we explore model adaptability to varied quality its potential mechanisms. Twenty‐eight products from multiple sources collected a headwater catchment Southern United States. These include...
Abstract Wet scavenging of aerosols by continental deep convective clouds is studied for a supercell storm complex observed over Oklahoma during the Deep Convective Clouds and Chemistry campaign. A new passive‐tracer‐based transport analysis framework developed to characterize using vertical profiles several passive trace gases. For this case, estimates that gas mixing ratios in upper troposphere outflow consist 47% low level (<3 km) inflow air, 32% entrained midtroposphere 21% air. The...
Despite the wide application of Weather Research and Forecasting (WRF) model in extreme precipitation simulations, there is a lack consensus clear guidance on identifying suitable length spin-up time. In this study, WRF was used to simulate events that happened 4 November 2015 at Alexandria Nile Delta. According observation from Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG), 21 time experiments 3-level-nested domain scenario 2-level-nested were designed...
Abstract Soil erosion delivers enormous amounts of macro-nutrients including nitrogen (N) and phosphorus (P) from land to rivers, potentially sustaining water column bioavailable nutrient levels for decades. In this study, we represent erosional N P fluxes in the Energy Exascale Earth System Model (E3SM) apply model continental United States. We estimate that during 1991–2019 soil 775 Gg yr −1 (1 = 10 9 g) particulate (PN) 328 (PP) on average drainage basins northern Gulf Mexico,...
Abstract The ability to simulate mixed lubrication problems has greatly improved, especially in concentrated lubricated contacts. A simulation method was developed by utilizing the semi-system approach which been proven be highly useful for improving stability and robustness of simulations. Then different variants model were varying discretization schemes used treat Couette flow terms Reynolds equation, evaluation density derivatives contribution coefficient matrix. resulting pressure...
Measurements of the ambient concentrations O 3 , NO x (NO + 2 ), and PAN (peroxyacetyl nitrate) were collected at Kenting, a rural site near southern end Taiwan, during autumn 1991 as part Pacific Exploratory Mission ‐ West A (PEM‐West A) experiment. Two principal component analyses (PCAs) performed on data. The results PCA indicated that least three different air mass types observed site, including marine boundary layer, urban plume, continental outflow (from Asian mainland). average...
The relation between the entropy exchange of an open atmospheric system in non‐equilibrium conditions with its environment and organization is examined terms theory dissipative structures. In this paper, integrative form balance equation a suitable for describing budget as whole derived starting from Gibbs relation, and, examples, flows West Pacific typhoon Bay Bengal cyclone are calculated. results show that negative have important effect on structures evolution good indicator life cycle system.
A finite difference method is proposed for solving the transport of intensity equation. Simulation results show that although slower than fast Fourier transform (FFT)-based methods, methods are able to reconstruct phase with better accuracy due relaxed assumptions equation relative FFT methods. Finite also more flexible in dealing different boundary conditions.
The Nile Delta has been suffering from complex environmental hazards caused by climate change and human-induced evolvements, which have led to adverse impacts on national food security. An unfavourable nexus between solid waste management issues extreme hydrological events is examined mainly through extensive field investigation literature research, an emerging issue affecting safety security whilst still being overlooked so far. findings not only reveal the significance of but also support...
The Solar Polar ORbit Telescope (SPORT) project for space weather mission has been under intensive scientific and engineering background studies since it was incorporated into the Chinese Space Science Strategic Pioneer Project in 2011.SPORT is designed to carry a suite of remote-sensing in-situ instruments observe Coronal Mass Ejections (CMEs),energetic particles,solar high-latitude magnetism,and fast solar wind from polar orbit around Sun. first extended view regions Sun ecliptic enabled...
High-resolution air temperature data is indispensable for analysing heatwave-related non-accidental mortality. However, the limited number of weather stations in urban areas makes obtaining such challenging. Multi-source fusion has been proposed as a countermeasure to tackle challenges. Satellite products often offered high spatial resolution but suffered from being temporally discontinuous due conditions. The characteristics reanalysis models were opposite. few studies have explored these...
