Relationship Among Sea Surface Temperature, ENSO and Indian Ocean Dipole in the Indian Ocean: A Clue to Recognizing Convective Systems
نویسنده
چکیده
The Northern Indian Ocean is unique in the global ocean because of seasonal reversal of winds as well as surface ocean currents. In the southern part of the Indian Ocean, a significant ocean-atmospheric phenomenon developed just like an El Nino phenomenon noticed in the Pacific Ocean. This phenomenon is known as the Indian Ocean Dipole. In this study we investigate the relationship between IOD and El Nino with sea surface temperature in identifying surface ocean convective cells those strengthens the monsoon.

A Look at the Relationship between the ENSO and the Indian Ocean Dipole
Using observed sea surface temperature data from 1871-1998, and observed wind data from 1958-1998, we have confirmed that the recently discovered Indian Ocean Dipole (IOD) is a physical entity. Many IOD events are shown to occur independently of the El Niño. By estimating the contribution from an appropriate El Niño index based on sea surface temperature anomaly in the eastern Pacific, we have ...
متن کاملInteraction Between the Indian Ocean Dipole and ENSO Associated with Ocean Subsurface Variability
The Indian Ocean dipole (IOD) is an intrinsic coupled mode of variability in the tropical Indian Ocean. It has broad impacts on regional climate. An IOD index is defined as the difference between sea surface temperature (SST) anomalies averaged over the western Indian Ocean (WIO, 50°–70°E, 10°S– 10°N) and eastern Indian Ocean (EIO, 90°– 110°E, 10°S–Eq.). An important issue in the studies of IOD...

متن کاملDistribution Modeling of Bigeye Tuna (Thunnus obesus Lowe, 1839), Using Satellite Derived Environmental Variables in Indian Ocean
Understanding effects of environment on the distribution of economic fish is a fundamental step in the ecosystem-based management and ultimately a standard approach in management policies. Bigeye tuna (Thunnus obesus) is one of the most important aquatic species harvested in the Indian Ocean. The present study investigated the association of different variables effecting the rate of catch and d...
