We study the wind climate and its long-term variability in the North Sea and South China Sea, areas relevant for offshore wind energy development, using satellite-based wind data, because very few reliable long-term in-situ sea surface wind observations are available. The Special Sensor Microwave Imager (SSM/I) ocean winds extrapolated from 10 m to 100 m using the Charnock relationship and the ...
Using the Weather Research and Forecasting (WRF) – Advanced Research WRF (ARW) mesoscale model (WRF–ARW), we investigate how two nocturnal offshore rainbands occurring in the Mediterranean basin are modified in a warmer sea surface temperature (SST). After sunset, the thermal difference between land and sea air increases. Driven by drainage winds or land breeze, the inland cold air interacts wi...
White-rot fungi (WRF) are ubiquitous in nature with their natural ability to compete and survive. WRF are the only organisms known to have the ability to degrade and mineralize recalcitrant plant polymer lignin. Their potential to degrade second most abundant carbon reserve material lignin on the earth make them important link in global carbon cycle. WRF degrade lignin by its unique ligninolyti...
Among the uncertain consequences of climate change on agriculture are changes in timing and quantity of precipitation together with predicted higher temperatures and changes in length of growing season. The understanding of how these uncertainties will affect water use in semiarid irrigated agricultural regions depends on accurate simulations of the terrestrial water cycle and, especially, evap...
Beta-glucosidase is among the suite of enzymes produced by white rot fungi (WRF) to biodegrade plant biomass. This study investigated the enzymatic activities and kinetic properties of β-glucosidase from seventeen WRF comprised of the following species from various geographical locations: Pleurotus ostreatus, Auricularia auricular, Polyporus squamosus, Trametes versicolor, Lentinula edodes, and...
A reliable application of a numerical weather prediction to short-range quantitative precipitation forecasting (QPF) is needed to forecast disastrous severe storms. The success of the dynamic, thermodynamic, and microphysical retrievals at the convective scale using Doppler radar observations are important but still great challenges. The use of three-dimensional variational data assimilation (3...
توسعه مزارع بادی جدید مستلزم ارزیابی دقیق از پتانسیل باد در طولانی مدت است. از این ارزیابی ها جهت تصمیم گیری برای نصب یک مزرعه بادی در یک مکان ویژه استفاده می شود. استفاده از مدل های میان مقیاس و خرد مقیاس یکی از روش های جدید پتانسیل سنجی برای این منظور است. این مطالعه نسل جدیدی از مدل عددی وضع هوا به نام مدل میان مقیاس wrf را مورد بحث قرار می دهد. در این روش برای ریز مقیاس نمایی داده های بای...
One of the grand challenges of the Global Precipitation Measurement (GPM) mission is to improve coldseason precipitation measurements in midand high latitudes through the use of high-frequency passive microwave radiometry. For this purpose, the Weather Research and Forecasting model (WRF) with the Goddard microphysics scheme is coupled with a Satellite Data Simulation Unit (WRF–SDSU) to facilit...
Since 2003 the National Center for Atmospheric Research (NCAR) has been running various experimental convection-allowing configurations of the Weather Research and Forecasting Model (WRF) for domains covering a large portion of the central United States during the warm season (April–July). In this study, the skill of 3-hourly accumulated precipitation forecasts from a large sample of these conv...
