چکیده مقاله :
زمینه و هدف: اجرای مدل های عددی جو با قدرت تفکیک بالا یکی از بهترین ابزارها جهت واکاوی جو در زمان رخداد پدیده های حدی می باشد. پژوهش حاضر به مدل سازی عددی پدیده جوی مسبب آبگرفتگی سواحل ایرانی خلیج فارس که در تاریخ 19 مارس سال 2017 به وقوع پیوست، پرداخته است.روش بررسی: مدل عددی مورد استفاده، نسخه 1/8/3 مدل WRF[1] با هسته دینامیکی[2]ARW می باشد که به کمک این مدل اقدام به ریز مقیاس نمایی و در واقع مدل سازی در منطقه انتخابی با مشخصات مرکزی عرض 27 درجه و 30 دقیقه شمالی و طول جغرافیایی51 درجه و 30 دقیقه شرقی با قدرت تفکیک 10 کیلومتر شده است.یافته ها: بعد از انجام مدل سازی عددی به کمک مدل WRF مشخص گردید که خروجی حاصل از مدل سازی پارامترهای جوی در منطقه مورد مطالعه با تعدادی از داده های واقعی اندازه گیری شده در ایستگاه سینوپتیک بخصوص دمای خشک و فشار تقریبا برابر بوده است. تحلیل نقشه و نمودارهای تولید شده به کمک مدل حکایت از وقوع توفان های تندری سوپر سلولی داردکه نتیجه آن خرد انفجارهای شدیدی است که بر روی سطح دریا در نزدیک سواحل بندر دیر رخ داده و نهایتا سبب ایجاد چهار موج و آبگرفتگی در این سواحل شده است.بحث و نتیجه گیری: براساس نتایج حاصل از خروجی های مدل، عامل اصلی رخداد این آبگرفتگی، وقوع یک توفان تندری سوپر سلول بر روی خلیج فارس و در فاصله نزدیک به سواحل بندر دیر تشخیص داده شد.[1] - Weather Research and Forecasting[2] - Advanced Research WRF
چکیده انگلیسی:
Background and Objectives: Implementation of numerical models of atmosphere with high resolution is one of the best tools to investigate the atmosphere at the time of occurrence of extreme phenomena. The present study has conducted to survey a numerical modeling of the atmospheric phenomenon which generated a water logging in Persian Gulf coastal area that occurred on March 19, 2017.Method: The WRF numerical model (version of 3.8.1) with the ARW dynamic core was used in this research. The WRF model are used to provide a dynamical downscaling and modeling in a selected domain with a central latitude of the 27° and 30 N and longitude 51° and 30׳ E in a 10 Km resolution.Results: The results showed that atmospheric variables modeling outputs in the study site were nearly equal to observed station data especially in dry temperature and pressure climatic variables. Also, the maps and diagram which is produced by model, indicated that a supercell thunderstorm has occurred which is caused the severe explosions occurring on the sea surface near the coast of Bandar Dayyer and eventually causing four waves and water logging on these coasts.Discussion and Conclusion: Based on the results of the model outputs, the main cause of this flood event was the occurrence of a supercell thunderstorms on the Persian Gulf near the coast of Bandar Dayyer.
