The Master Plan of the Shagaya Renewable Energy Park in Kuwait
Yousuf Al-Abdulla | Kuwait Institute for Scientific Research, Kuwait City, Kuwait
Abstract
Kuwait is developing a large (2G) renewable energy facility, including solar and wind, called Shagaya. Kuwait is located on the north end of the Arabian Gulf and experiences the full range of weather conditions through-out the year. The Shagaya facility is located in the desert west of Kuwait city. Several Kuwaitis are visiting NCAR to learn more about renewable power forecasting for the Shagaya facility. This seminar will cover the current plans for renewable energy in Kuwait and highlight areas where they are looking for further collaboration.

Shallow convective clouds are ubiquitous, and warm rain largely contributes to the total annual rainfall, particularly in the tropics. Therefore, understanding the microphysical processes inside these cloud systems becomes important. Classical parcel models often produce narrow droplet size distributions (DSDs) which disagree with observations in cumulus clouds. Since the last century, turbulence have been postulated to explain the effective DSD broadening in early cloud stage.
This work studies the very fundamental process involving droplet condensational and collisional growth to explore the fast warm-rain initiation using the direct numerical simulation (DNS). DNS model can accurately resolve small-scale turbulence and simulates the turbulence impacts on droplets that are tracked in the Lagrangian framework, which is infeasible in other models.
This is the first modeling study that incorporates both droplet condensational process and collisional process into the DNS model and investigates the full droplet growth history in the turbulent environment.
Model results show that condensational growth by itself produces narrow DSD under small-scale turbulence, which is similar to the parcel model results. Results from the simulations that consider pure collision-coalescence process show that small-scale turbulence significantly increases the collision rate between small droplets and thus accelerates the formation of large droplets. In particular, the enhancement is the strongest between similar-sized droplets, which indicates that turbulence effectively broadens the narrow DSD formed by condensational growth. On the other hand, condensational growth considerably brings tiny droplets to 5-10 microns, dynamically shifting the collision rates of those droplets in turbulence. To study how collisional process and condensational process interact under the effect of turbulence, simulation results that consider both condensational and collisional processes will be compared to pure collision-coalescence case. It is shown that the inclusion of condensation significantly changes the behavior of droplet collisions in the turbulence and thus has strong feedback on the DSD broadening. Detailed results and comparison will be presented in the talk.

Eric Defer Laboratoire d'Aérologie, CNRS - Université de Toulouse – OMP – UPS, Toulouse, France The 4-year EXAEDRE (EXploiting new Atmospheric Electricity Data for Research and the Environment; Oct 2016-Sept 2020) project is sponsored by the French Science Foundation ANR (Agence Nationale de la Recherche). This project is a French contribution to the HyMeX (HYdrological cycle in the Mediterranean EXperiment) program. The EXAEDRE activities rely on innovative multi-disciplinary and state of the art instrumentation and modeling tools to provide a comprehensive description of the electrical activity in thunderstorms. The EXAEDRE observational part is based on i) existing lightning records collected during HyMeX Special Observation Period (SOP1; Sept-Nov 2012), and permanent lightning observations provided by the research Lightning Mapping Array SAETTA and the operational Météorage lightning locating systems, ii) additional lightning observations mapped with a new VHF interferometer especially developed within the EXAEDRE project, and iii) a dedicated airborne campaign over Corsica. The modeling part of the EXAEDRE project relies on the electrification and lightning schemes implemented in the French cloud resolving model MesoNH and on Météo-France operational model AROME for innovative investigation of lightning data assimilation.An overview of the EXAEDRE project will be given with an emphasis on both observational and modeling activities performed during the 1st year of the project. The preparation of the EXAEDRE airborne campaign planed in September 2018 over Corsica will then be discussed.Acknowledgements: the EXAEDRE project is sponsored by grant ANR-16-CE04-0005-01 with support from the MISTRALS/HyMeX meta program.

LAURA CLEMENTE-HARDING | THE PENNSYLVANIA STATE UNIVERSITY, UNIVERSITY PARK, PA, AND THE ENGINEER RESEARCH AND DEVELOPMENT CENTER, ALEXANDRIA, VA
Have you heard about the Analog Ensemble (AnEn) technique? Would you like to learn more about the technique and its evolution? Want to learn its possible applications and the current state-of-the-art research being conducted using this technique? Then come for a beginners adventure into the AnEn technique brought to you by the Warner Internship for Scientific Enrichment (WISE) Program!
The Analog Ensemble (AnEn) technique was developed to generate a probability distribution function (PDF) of an expected outcome from a current deterministic forecast and corresponding sets of historical forecasts and verifying observations. The technique has implications in physical science subject areas where: 1) single deterministic predictions, past predictions, and their corresponding observations are available; 2) it is necessary to have quantifiable and justifiable measures of uncertainty; and 3) computational resources are precious. The AnEn technique provides an alternative option for generating probabilistic forecasts without requiring the computational expense of a NWP ensemble thus allowing scientists to choose between the tradeoff of higher resolution modeling or ensemble modeling at a coarser resolution. The AnEn improves short-term weather prediction accuracy, decreases real-time computational costs, and provides spatial and temporal uncertainty estimation (Delle Monache et al. 2011; Delle Monache et al. 2013; Alessasndrini et al. 2015; Zhang et al. 2015). Applications of the technique include but are not limited to: a range of weather parameters (e.g., 10-m and 80-m wind speed, 2-m temperature, relative humidity) solar power forecasting, wind power forecasting, air quality forecasting, tropical cyclone predictions, and downscaling of parameters as wind speed and precipitation.

Day-to-day variability of weather like temperature, precipitation, and wind—which is distinct from natural catastrophes like hurricanes and severe thunderstorms—can have significant financial impact on sectors like energy, agriculture, water, construction, and outdoor entertainment, amongst others. Businesses and governments that hold weather risk can choose to transfer it to a financial institution like an insurer. They shed weather risk by paying a premium to the financial institution, in exchange for financial protection when weather is bad for business operations. Weather risk transfer has grown into a multi-billion dollar market because of ample historical weather data; a large appetite of financial institutions for weather risk; and the intuitive relationship between weather and the financial performance of weather-exposed entities. However, market growth has been slower than expected. This is largely due to a lack of independent advisors who understand weather and have the analysis expertise to quantify the linkages between weather and a weather-exposed entity’s financial performance. Such an advisor would be well positioned to translate weather into the financial concern of interest, creating an environmental and economic opportunity for the advisor, weather-exposed entities, sellers of financial protection, and the broader weather risk transfer market.
At Nephila Advisors LLC, Matthew has the role of Portfolio Analyst and works within the Weather Risk investment strategy. Matthew's expertise includes designing customized risk transfer products; quantifying the frequency and severity of weather and water events; and ongoing portfolio management and business development. He joined the company in July 2011 and previously worked at Citadel LLC and the National Center for Atmospheric Research (NCAR), giving him a unique blend of experience in capital markets, insurance, and weather risk management. Matthew has an MBA in Finance from the University of Virginia’s Darden School of Business, an MS in Meteorology from the Pennsylvania State University, and a BS in Chemistry and Environmental Sciences from the University of Virginia. Matthew is an alumnus of NCAR’s SOARS internship program.
