A comparative study of quantitative mapping methods for bias correction of ERA5 reanalysis precipitation data
This study evaluates the ability of different quantitative mapping (QM) methods as a bias correction technique for ERA5 reanalysis precipitation data. Climate type and geographical location can affect the performance of the bias correction method due to differences in precipitation characteristics. For this purpose, ERA5 reanalysis precipitation data for the years 1989-2019 for 10 selected syno...
متن کاملtrend analysis of the recent seasonal changes in subtropical jet stream in climateof iran
introduction according to the definition of world meteorology organization (wmo), as the speed of the air mass is more than 30 meters per second, the jetstream will arise. the core of the jetstream is with baroclinic atmosphere due to the large difference in temperature and wind speed. there are two west jetstreams in the northern hemisphere. the northern jet stream is called polar front jetstr...
متن کاملthe role of subtropical jet-stream in daily precipitation more than 10 mm in zayanderood basin
introduction zayanderood basin is one of the major internal river basins in the central iran, where zayanderood river is the only permanent river. fluctuations in rainfall in recent years have affected different areas of iran. because of the dependence of the provinces of isfahan, yazd, and kerman on water resources of this basin, changes and fluctuations in precipitation within this watershed ...
متن کاملLagrangian Coherent Structures near a Subtropical Jet Stream
Direct Lyapunov exponents and stability results are used to extract and distinguish Lagrangian coherent structures (LCS) from a three-dimensional atmospheric dataset generated from the Weather Research and Forecasting (WRF) model. The numerical model is centered at 19.788N, 155.558W, initialized from the Global Forecast System for the case of a subtropical jet stream near Hawaii on 12 December ...
متن کاملthe clustering and classification data mining techniques in insurance fraud detection:the case of iranian car insurance
با توجه به گسترش روز افزون تقلب در حوزه بیمه به خصوص در بخش بیمه اتومبیل و تبعات منفی آن برای شرکت های بیمه، به کارگیری روش های مناسب و کارآمد به منظور شناسایی و کشف تقلب در این حوزه امری ضروری است. درک الگوی موجود در داده های مربوط به مطالبات گزارش شده گذشته می تواند در کشف واقعی یا غیرواقعی بودن ادعای خسارت، مفید باشد. یکی از متداول ترین و پرکاربردترین راه های کشف الگوی داده ها استفاده از ر...
