Default values for many parameters in Numerical Weather Prediction models are typically adopted based on theoretical or experimental investigations by scheme designers. Short‐range forecasts are substantially affected by the specification of parameters in the Weather Research and Forecasting (WRF) model. The presence of a multitude of parameters and several output variables in the WRF model renders appropriate parameter value identification quite challenging. This study aims to identify the parameters that most strongly influence the model output variables using a Global Sensitivity Analysis (GSA) method. Morris One‐At‐a‐Time (MOAT), a GSA method, is used to identify the sensitivities of 23 chosen tunable parameters corresponding to seven physical parameterization schemes of the WRF model. The sensitivity measures (MOAT mean and standard deviation) are evaluated for 11 output variables simulated by the WRF model, corresponding to different parameters. Twelve high‐intensity 4‐day precipitation events during the Indian summer monsoon during 2015, 2016, and 2017 over India's monsoon core region are considered for the study. Though the parameter sensitivities vary depending on the model output variable, overall results suggest a general trend. The consistency of sensitivity analysis results with different initial and lateral boundary conditions is also assessed.
Introduction: Trauma has been called the neglected disease of modern society, despite its close companionship with man1. Abdominal trauma caused by blunt force is a common presentation in the emergency room seen in adults and children. They are usually an outcome of road trafc accidents, fall from heights or fall on any blunt objects or due to assaults2. They are associated with a high morbidity and mortality which can be avoided with early diagnosis and management. To study the correlation Objective: of preoperative diagnosis made by radiological evaluation with the intraoperative ndings in cases of blunt abdominal trauma. Materials and methods: The present study was conducted on 60 clinically suspected patients of blunt abdominal trauma presenting to the Emergency Department, King George Hospital, Visakhapatnam. The study was conducted after prior approval by the Institutional Ethics Committee and informed and written consent from the patient. 60 patients with clinical suspicion of blunt abdominal trauma were selected. After thorough clinical examination, the patients were subjected to X-ray chest and abdomen, Ultrasonography (USG) and Computed Tomography (CT) imaging. After arriving at a pre-operative diagnosis, these patients were followed up and correlation of this diagnosis was done with the intraoperative ndings and the results were evaluated. The data entry was done using M.S.Excel and statistical analysis was done using Statistical package for social sciences (SPSS version 16) for M.S.Windows. Fischers exact test was used. p-value less than 0.05 was considered to be statistically signicant. It was observed that preoperative diagnosis ma Results: de with CT had a higher degree of correlation with the intraoperative ndings when compared to Ultrasonography. It can be concluded that CT i Conclusion: s a better tool for preoperative evaluation when compared to USG in cases of blunt abdominal trauma
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
