چکیده
مدل‌سازی جبهه‌های آب در شمال اقیانوس هند و سواحل مکران یک رویکرد مهم است که به بررسی و پیش‌بینی تغییرات جبهه‌های آب در این منطقه می‌پردازد. مدل سازی جبهه‌های آب در شمال اقیانوس هند با استفاده از داده‌های شوری و دما، به تصویر کشیدن الگوهای جغرافیایی و زمانی جابجایی جبهه‌ها کمک می‌کند و به عنوان یک ابزار پیشرفته و پژوهشگرانه در این زمینه استفاده می‌شود. این مقاله بخشی از یک مدل‌سازی جامع را در آبهای اقیانوس هند ارائه می-دهد که به شکل‌گیری توده‌های آب و جبهه های دما و شوری مرتبط است. در این مد‌ل‌سازی از مجموعه مدل سه بعدی Delft3D استفاده شده است و جبهه‌های سطحی و زیرسطحی آب در منطقه مورد مطالعه استخراج شده است. نتایج این مطالعه، شکل‌گیری چند جبهه مهم را در منطقه مورد مطالعه نشان می‌دهد. یکی از این جبهه‌ها در امتداد سواحل مکران شکل می گیرد و محدود به لایه سطحی آب دریا می شود. جبهه دیگر در غرب دریای عمان واقع شده است و می‌تواند به دلیل خروج آب گرم و شور خلیج فارس به خلیج عمان باشد. گستره این جبهه در فصل سرد سال در عمقهای حدود 200 تا 300 متر تقریبا کل ناحیه غرب خلیج عمان را پوشش می دهد اما در فصل گرم سال، بیشتر در لایه سطحی دریا گسترده شده است و هرچه به سمت عمق پیش رویم جبهه به سمت سواحل جنوب غرب محدود می‌شود.

چکیده English

Modeling of water fronts in the northern Indian Ocean and Makran coast is an important feature that investigates and predicts the changes of water fronts in this region. Modeling of water fronts in the northern Indian Ocean by using salinity and temperature data helps to depict the geographical and temporal patterns of the movement of the fronts and is used as an advanced and research tool in this field. This paper presents a comprehensive modeling of Indian Ocean waters related to the formation of water masses and temperature and salinity fronts. In this modeling, Delft3D next-generation models are used, and the surface and subsurface levels of water in the study area have been investigated. The results of this study show the formation of several important fronts in the studied area. One of these fronts is formed along the coast of Makran and is limited to the surface layer of water. The other front is located in the west of the Oman Sea and can be the outflow of warm and salty water from the Persian Gulf to the Gulf of Oman. The extent of this front in the cold season of the year covers the entire area of the western Gulf of Oman at a depth of 200 to 300 meters, but in the warm season of the year, it is mostly located in the surface layer of the sea, and as we go deeper, it is located on the south coast. takes the west is limited.
