Study Uses WRF Model to Analyze Extreme Weather Event and Enhance Precipitation Predictions

Changes in rainfall patterns directly impact hydrological processes in general and the timing and magnitude of floods in particular. Therefore, it is necessary to have accurate predictions of precipitation timings and amounts, along with their impact on resulting runoff to produce reliable flash flood guidance. Prof. Volker Wulfmeyer, a First Cycle Awardee of the UAE Rain Enhancement Program (UAEREP) and Managing Director and Chair of Physics and Meteorology at the Institute of Physics andRead more...

Study Uses Geostationary Satellite Data to Assess Seasonal Cloud Properties over the UAE and Adjoining Regions

Declining groundwater reserves and costly desalination plants have prompted the UAE and the neighboring countries with similar arid and semi-arid climatic conditions to search for alternative water resources through rainfall enhancement, specifically cloud seeding. However, a limited number of studies focused on the Arabian Peninsula’s cloud climatology and the seasonal variability in cloud microphysical properties and dynamics, which form the bases for precipitation augmentationRead more...

Study Investigates Using Nanostructured Cloud seeding Materials for Rain Enhancement

Bioinspired materials provide an effective method to replicate nature’s design principles in building complex and sophisticatedly engineered systems at various length scales, allowing us to solve critical water stress challenges. A successful example for such systems is the water-augmentation materials inspired by the structure-dependent water-vapor harvesting systems in nature, such as insects and plants which can survive in the desert or regions with limited rainfall. The advantagesRead more...

New Study Reports on Consistent Dust Electrification from Arabian Gulf Sea Breezes

Electrification of dust in the atmosphere occurs as a result of contact charging or triboelectrification during dust generation or its atmospheric transport. Dust is lifted from the surface by the wind, and enhanced by saltation and resuspension. Collisions between dust particles cause charge to be transferred between them, resulting in a net charge on the particles depending on particle size and composition. Dust electrification has applications to climate studies, through electricalRead more...

Study Investigates Role of Atmospheric Aerosol Concentration on Regional Cloud Precipitation Patterns

The Earth’s energy budget involves the exchange of energy between three levels: its surface, the top of the atmosphere and the atmosphere in between. In this system, aerosols - the small particles suspended in the Earth's atmosphere from sources such as desert dust, sea salt, volcanic ash, sulfate, and black carbon - play an important role in introducing uncertainties in weather and climatic predictions. Of all aerosol types, windblown mineral dust is one of the most mass abundantRead more...

Study Analyzes Influence of Atmosphere Near-Surface Layer Properties on Development of Cloud Convection

The formation of clouds and precipitation is affected by the rise of moist air, its cooling, and condensation of the water vapor. The upward motion of air is triggered by either free air convection due to thermal instabilities of the atmosphere, or by the effect of the dynamic factors associated with the passage of atmospheric fronts, or flows around complex terrain. A number of studies have examined the development mechanisms of free thermal convection depending on the characteristics ofRead more...

Study Investigates Ascent Rate of Moist Deep Convective Thermals for Improving Cumulus Parameterizations

Since the 1950s, two primary conceptual models have served as a basis for the scientific community’s understanding of the structure and behavior of atmospheric moist convection: the steady-state entraining plume model, and the non-steady thermal model entraining buoyant bubble rising through a fluid. The plume and thermal models predict markedly different structure and flow characteristics. To gain a better understanding of thermal dynamics, and its practical importance for improvingRead more...

Study Demonstrates Efficiency of PrGO-SN Composite as Ideal Nucleation Materials for Cloud Seeding

The transformation of liquid water into solid ice is a common natural phenomenon, where ice can be formed homogeneously by pure water, or heterogeneously in the presence of foreign materials called Ice Nucleating Particles (INPs). Such INPs can originate from biological, mineralogical, and anthropogenic sources, including pollen and bacteria, volcano ashes, and atmospheric dust. Heterogeneous ice nucleation plays an important role in various areas, such as atmospheric physics,Read more...
