In this study, the performance of SWAN (Simulating WAves Nearshore) spectral wave model ST6 physics forced by ERA5 reanalysis wind data were evaluated in predicting properties an enclosed basin, Black Sea. validated against in-situ measurements. Although two match quite well, a 10–20% underestimation speeds and velocity components was found. Spectral modeling study conducted phases. first phase...

Marine oil spills occur suddenly and pose a serious threat to ecosystems in coastal waters. Oil continuously affect the ocean environment for years. In this study, spill caused by accident of Sanchi ship (2018) East China Sea was hindcast simulated using particle-tracing method. Sea-surface winds from European Centre Medium-Range Weather Forecasts (ECMWF), currents Finite-Volume Community Ocean...

Polar lows (PLs) are intense mesoscale weather systems that often cause severe storm winds in the Nordic Seas but were considered as being exceedingly rare Pacific Arctic region before sea ice decline. Here, we explore four PLs observed on 18–22 October 2017 Chukchi and Beaufort Seas—an area with an exceptionally sparse observation network. The study is based combined use of satellite microwave...

پیشرفت و بهبود پیش بینی های عددی ، موجب توجه بیش از پیش برنامه ریزان و بهره برداران سیستم های منابع آب به این اطلاعات شده است. اغلب ارزیابی ها در زمینه پیش بینی های فصلی ، بر مبنای داده های ایستگاهی زمینی و یا داده های شبکه بندی صورت می گیرد. در این تحقیق در راستای ارزیابی عملکرد پیش بینی مدل CFSv2 ،تحلیل‌ها در مقیاس حوضه آبریز انجام شده است و به منظور ایجاد یک سری زمانی با طول دوره مناسب جهت ت...

A fully coupled tide-surge-wave model was developed to study the influence of different computational domains on typhoon wave characteristics in waters surrounding Taiwan. Three typhoons were selected as cases: Meranti, Malakas, and Megi, which successively impacted Taiwan September 2016. Superposition CFSV2 winds blended with ERA5 onto yielded optimum simulations waves. Storm responses along e...

Abstract. The California Pacific coast is characterized by considerable wind resource and areas of dense population, propelling interest in offshore energy as the United States moves toward a sustainable decarbonized future. Reanalysis models continue to serve community multitude ways, need for validation locations where observations have been historically limited, such environments, strong. U....

Precipitation change, which is closely related to drought and flood disasters in China, affects billions of people every year, the demand for subseasonal forecasting precipitation even more urgent. Subseasonal forecasting, difficult than weather however, has remained as a blank area meteorological service long period time. To improve accuracy China precipitation, this work introduces machine le...

عملکرد RegCM4 با چهار پارامترسازی مختلف برای شبیه­سازی دمای هوای نزدیک سطح زمین و بارش در منطقه ایران طی سال 2010 در مقایسه با داده­های مشاهداتی CRU بررسی شد. در این بررسی از داده­های مدل CFSv2 به­عنوان شرایط اولیه و مرزی RegCM4 استفاده شد. بررسی الگوی اریبی دمای هوا در این شبیه­سازی­ها نشان داد که بیشترین اریبی منفی در سواحل جنوبی دریای خزر و ارتفاعات رشته کوه البرز و بیشترین اریبی مثبت در دشت...
