The spatial and temporal monitoring of the sea surface temperature anomaly of the Strait of Hormuz

Fertile coastal area is one of the challenges of marine science. This study identifies the upwelling areas in the Strait of Hormuz (52˚E to 59˚E, 23˚N to 28˚N) by using data satellite images of Sea Surface Temperature Anomaly (SSTA) in a period of 20 years (July 2002 to June 2021). Four coastal stations named Lavan, Abu Musa, Qeshm, and Jask were selected as a case study of this scope. The global monthly Multi-scale Ultra-high Resolution (MUR) of Sea Surface Temperature (SST) analysis anomaly by 0.01° resolution was used to find colder areas. The data were analyzed by Matlab. The satellite image results illustrated that the SSTA pattern showed both temporal and spatial fluctuations. The results of two decades of data showed well the spatial (between east-west and north-south) and temporal (August-November) fluctuations in the Strait of Hormuz. The Marine Heat Wave (MHW) started in June and made August the hottest month of the year. The duration of MHW was four months. While November was recognized as the coldest month in these two decades of data and SSTA of the curve of the strait reached less than -0.1°C. There was a permanent warm eddy (SSTA=0.2489°C) at 25.93°N and 53.23°E with the diameter of 55 km. It was also confirmed a permanent upwelling in Jask areas in the east of the Strait of Hormuz.
