Abstract:
... Green roof, as a popular low impact development practice, has become important to mitigate adverse impacts of future climate change on urban stormwater. However, there is limited information regarding assessment of the effectiveness of green roofs in response to uncertain future climate change challenges. In this study, the validated model was used to simulate the reduction performance of green ro ...

Abstract:
... The Covid-19 crisis has caused several social-related issues; the sanitary is, perhaps, the most significant one. Lockdowns and vaccination were implemented to fight the Covid-19 virus. From a sustainability perspective, Covid-19 has been considered a meaningful crisis driver that has affected nations' economies and social and natural capitals. The literature presents clues that effects appear to ...

Abstract:
... Complex transformations of heavy metals in the mega-river-estuary continuum limit our understanding of their pollution history. This study investigated sedimentary compositions of heavy metals, major elements, total organic carbon, grain size, and radionuclides to study spatiotemporal variations in heavy metal accumulation patterns and their controlling mechanisms in four sediment cores (E1-E4) fr ...
... This paper describes the initial results of precipitation estimates from the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) Millimeter-wave Sounder (TMS) using the Precipitation Retrieval and Profiling Scheme (PRPS). The TROPICS mission consists of a Pathfinder CubeSat and a constellation of six CubeSats, providing a low-cost s ...

Abstract:
... Gamma-Flash is an Italian program devoted to the realization of both a ground-based and an airborne gamma-ray and neutron detection system, for in situ measurements of high-energy phenomena correlated to thunderstorm activity, such as Terrestrial Gamma-ray Flashes (TGFs), gamma-ray glows, and associated neutron emissions. The ground-based Gamma-Flash experiment is currently under installation at t ...

Abstract:
... In this paper we demonstrate a novel framework for assessing nature-based solutions (NBSs) in coastal zones using a new suite of numerical models that provide a virtual “replica” of the natural environment. We design experiments that use a Digital Twin strategy to establish the wave, sea level and current attenuation due to seagrass NBSs. This Digital Twin modelling framework allows us to answer “ ...

Abstract:
... Precise forecasting of tropical cyclone-induced storm surges is necessary to avoid any significant damages to coastal communities. The numerical models need wind and pressure fields as a surface forcing to predict these events. An increase in the quality of the available wind field data greatly benefits the forecast. There remain inherent limitations in the quality of real-time wind forecasts for ...

Abstract:
... The detachment and mobilization of boulders from rocky shore platforms by waves involves complex geomorphic and hydrodynamic processes. Understanding these processes requires precise information on the rates and patterns of movement of these megaclasts scaled against the wave conditions that generate boulder mobility. Repeat photogrammetry and structure-from-motion (SfM) models commonly used in ge ...

Abstract:
... Radar echo extrapolation has been widely developed in previous studies for precipitation and storm nowcasting. However, most studies have focused on two-dimensional radar images, and extrapolation of multi-altitude radar images, which can provide more informative and visual forecasts about weather systems in realistic space, has been less explored. Thus, this paper proposes a 3D-convolutional long ...

Abstract:
... The warm-phase version of the Spectral-Bin Microphysics (SBM) scheme has been implemented into the ICON model and has been tested in a supercell storm simulation. The results of two-moment (2M) bulk scheme which exists in ICON and SBM were compared in all aspects related to warm processes, especially with regards to sensitivity to aerosols. In all simulations a strong storm with maximum updrafts e ...

Abstract:
... Climate change is not only changing the mean values of environmental parameters that modulate ecosystems, but also the regime of disturbances. Among them, extreme events have a key role in structuring biological communities. Ecosystems are frequently suffering multiple anthropogenic pressures which can cause effects that are not additive. Thus, the effects of extreme events need to be studied in c ...

Abstract:
... Flash rips are episodic bursts of water jetting offshore, which can lead to drowning incidents by sweeping swimmers offshore without warning, thus posing a hidden and unrecognized danger to beachgoers. This study reveals hazards of flash rips by investigating a series of drowning incidents along coasts of Lake Michigan during a series of storm events on July 18–21, 2019. Occurrences and causes of ...

Abstract:
... Free wave generation due to a ship or storm moving past a shallow, great depth change of the water, is measured on the shore (coast), modeled and compared. The free waves are generated at the depth change where the forced wave and velocity field attached to the moving pressure system adjust to the new depth. The wavenumber is a factor 1/12 smaller in the meteotsunami case compared to the ship case ...

Abstract:
... On 22 June 2017, an extreme warm-sector rainfall event hit the western coastal area of South China, with maximum hourly and 12-h rainfall accumulations of 189.4 and 464.8 mm, respectively, which broke local historical records. Multisource observations were used to reveal multiscale processes contributing to the extreme rainfall. The results showed that a marine boundary layer jet (BLJ) coupled wit ...

Abstract:
... Immersive virtual reality (iVR) can enable users to experience phenomena at real-world scale. This attribute may be useful for communicating the risks of many natural hazards. Storm-surge is a flood hazard whose risk has proven challenging to communicate through traditional means, such as maps. When it comes to storm-surge flooding, iVR experiences have shown promise in increasing awareness of the ...

Abstract:
... Distributed infiltration systems can benefit downstream water bodies by reducing the runoff flowrate and volume discharges from the catchment. Investigating their runoff flowrate and volume reduction potential at the catchment scale will inform decision makers regarding their efficacy for managing catchment outflows. To this end, we conducted field investigations at the residential catchment scale ...

Abstract:
... Relativistic runaway electron avalanches (RREA) occurring in thunderstorm large-scale electric fields are one of the sources of atmospheric gamma radiation. Relativistic feedback is the generation of RREAs by positrons or backscattered gamma rays of the previously produced RREAs. In strong electric fields, relativistic feedback can make RREAs self-sustainable that hypothetically can cause a terres ...
