The exposure of the Earth's surface to energetic input rainfall is one key factors controlling water erosion. While erosion identified as most serious cause soil degradation globally, global patterns erosivity remain poorly quantified and estimates have large uncertainties. This hampers implementation effective mitigation restoration strategies. Quantifying challenging it requires high temporal resolution(<30 min) fidelity recordings. We present results an extensive data collection effort...
Here, we present and release the Global Rainfall Erosivity Database (GloREDa), a multi-source platform containing rainfall erosivity values for almost 4000 stations globally. The database was compiled through global collaboration between network of researchers, meteorological services environmental organisations from 65 countries. GloREDa is first open access (R-factor) based on hourly sub-hourly records at scale. This now stored accessible download in long-term European Soil Data Centre...
ABSTRACT An evaluation of 23 models, participating in the Coupled Model Inter‐comparison Project phase 5 (CMIP5), representing extreme precipitation indices (EPI), over Eastern Mediterranean (EM) and Fertile Crescent (FC), was performed. The models ensemble then used to predict EPIs evolution 21st century under (Representative Concentration Pathway, RCP) RCP4.5 RCP8.5 scenarios. Models' performance determined with respect gridded observations from APHRODITE project. mean found perform...
Background: Exposure to heat during pregnancy has been associated with reduced fetal growth. Less is known about associations cold and the potential for critical time windows of exposure. Objectives: We aimed evaluate, in a national retrospective cohort, susceptibility extreme temperatures (low high) growth, among 624,940 singleton term births Israel period 2010–2014. Methods: Temperature exposures were estimated using spatially refined gridded climate data set 1-h 1-km2 resolution....
Abstract After 38 years of operational cloud seeding for rain enhancement in northern Israel, the Israel 4 experiment was conducted to reassess its effect on rainfall and provide a basis evaluate utility. Operational started after two randomized experiments, second ending 1976, found large statistically significant rainfall. Observational studies later raised doubts as magnitude effect, possibly because changing climatological conditions. A carefully designed from 2013 2020. unique feature...
Abstract. Flash floods are among the most devastating and lethal natural hazards. In 2018, three flash-flood episodes resulted in 46 casualties deserts of Israel Jordan alone. This paper presents hydrometeorological analysis forecasting a substantial storm (25–27 April 2018) that hit an arid desert basin (Zin, ∼1400 km2, southern Israel) claiming 12 human lives. aims to (a) spatially assess severity storm, (b) quantify timescale hydrological response, (c) evaluate available operational...
Abstract. In September 2015 one of the severest and most unusual dust events on record occurred in Eastern Mediterranean. Surprisingly, operational transport models were unable to forecast event. This study details reasons for this failure presents simulations event at convection-permitting resolution using modelling system ICON-ART. The results allow an in-depth analysis influence synoptic situation, complex interaction multiple driving atmospheric systems mineral radiative effect A...
The climate factor has become a focus of much historical and archaeological investigation, encouraged recently by improvements in palaeoclimatic techniques interest global change. This article examines correlations between history the Byzantine southern Levant (c. 4th–7th centuries AD). A proposed 5th century economic downturn attested to numismatic trends is shown coincide with evidence for drought. We suggest climatic ultimate cause apparent decline. In addition, relationship Dust Veil...
Among the varied environmental factors that influence insect life-history, temperature has a relatively profound effect can be mathematically estimated with non-linear equations. Thus, many models aim to predict insect-pest population dynamics use meteorological data as input descriptive functions development rate, survival and reproduction of pest populations. In previous study, we developed temperature-dependent model for global Bemisia tabaci, verified its accuracy under field conditions....
Abstract The East Mediterranean Sea (EMS) circulation has previously been characterized as dominated by gyres, mesoscale eddies, and disjoint boundary currents. We develop nested high-resolution numerical simulations in the EMS to examine variability with an emphasis on yet unexplored regional submesoscale Rather than several currents, a continuous cyclonic current (BC) encircling Levantine basin is identified both model solution altimetry data. This BC advects eddy chains downstream...
Abstract Shallow convection is a subgrid process in cloud-resolving models for which their grid box larger than the size of small cumulus clouds (Cu). At same time such Cu substantially affect radiation properties and thermodynamic parameters low atmosphere. The main microphysical used calculation radiative are liquid water content (LWC), effective droplet radius, cloud fraction (CF). In this study, these fields small, warm calculated using large-eddy simulations (LESs) performed System...

This study analyzed the temporal and spatial variation of natural ice nuclei (IN), total suspended particles (TSP), rainwater chemical composition (RCC) in Israel. research is complementary to statistical analyses cloud seeding, which have shown significant positive seeding effects only northern Israel, together with detrimemtal desert dust. It was observed that concentration continental components dissolved increases by about an order magnitude from southern High values IN, TSP, origin...
Abstract. The significance of planetary boundary layer (PBL) height detection is apparent in various fields, especially air pollution dispersion assessments. Numerical weather models produce a high spatial and temporal resolution PBL heights; however, their performance requires validation. This necessity addressed here by an array eight ceilometers; radiosonde; two – the Integrated Forecast System (IFS) global model COnsortium for Small-scale MOdeling (COSMO) regional model. ceilometers were...
