background bladder reconstruction in the pediatric population is challenging for many reasons, including perioperative complications and readmissions. objectives on a national scale, determine readmission rates at 30, 60 and 90 days after bladder reconstruction in a pediatric population over a 7-year period, evaluating the influence of hospital and patient-specific variables. patients and metho...
Abstract The stratosphere is the second layer of atmosphere and important this to contain ozone which absorbs UV radiation from Sun. main objective research study effect GHGs TCO on temperature in presence influence solar mid-latitude region, specifically capital Beijing (latitude 40°N; longitude 116°E) China are taken as a case, because it most city world that emits greenhouse gases for period...
Abstract. The European Centre for Medium-Range Weather Forecasts (ECMWF) mission is to deliver high-quality global medium-range numerical weather predictions and monitoring of the Earth system its member states. modelling forecasting natural hazards are an important part this mission. Challenges in area include integration innovative observations into system; realistic representations water, en...
باد یکی از پارامترهای مهم اقلیم است و بهعنوان یک شاخص مناسب میتواند برای تغییرات اقلیمی و الگوهای مرتبط با جریان هوا بهکار برده شود. هدف از این تحقیق بررسی روند تغییرات بلندمدت سرعت باد در ایران مرکزی است. به این منظور، از دادههای سرعت باد پایگاه بازتحلیلشدة ECMWF نسخة ERA-Interim با تفکیک مکانی 75/0×75/0 درجة قوسی و دادههای هفت ایستگاه سینوپتیک طی دورة آماری ۱۹۸۰-2017 استفاده شد. برای در...
Early and skilful prediction of the Negro River maximum water levels at Manaus is critical for effective mitigation measures to safeguard lives livelihoods. Using dynamical seasonal hindcasts, from six centres, we investigate extending lead time previously developed statistical models, which issue forecasts in March Manaus. The original forecast models used observed rainfall as major predictor....
A representation of atmospheric chemistry has been included in the Integrated Forecasting System (IFS) of the European Centre for Medium-Range Weather Forecasts (ECMWF). The new chemistry modules complement the aerosol modules of the IFS for atmospheric composition, which is named C-IFS. C-IFS for chemistry supersedes a coupled system in which chemical transport model (CTM) Model for OZone and ...
