The Indian Ocean is the warmest ocean in the world. [25] Long-term ocean temperature records show a rapid, continuous warming in the Indian Ocean, at about 1.2 °C (34.2 °F) (compared to 0.7 °C (33.3 °F) for the warm pool region) during 1901–2012. [26]
The extent of the ocean surface down into the ocean is influenced by the amount of mixing that takes place between the surface water and the deeper water. This depends on the temperature: in the tropics the warm surface layer of about 100 m is quite stable and does not mix much with deeper water, while near the poles winter cooling and storms makes the surface layer denser and it mixes to ...
Water temperatures around the Mentawai Islands dropped about 4 °C during the height of a positive phase of the Indian Ocean Dipole in November 1997. During these events unusually strong winds from the east push warm surface water towards Africa, allowing cold water to upwell along the Sumatran coast. In this image blue areas are cooler than ...
The increase of both ocean surface temperature and deeper ocean temperature is an important effect of climate change on oceans. [11] Deep ocean water is the name for cold, salty water found deep below the surface of Earth's oceans. Deep ocean water makes up about 90% of the volume of the oceans.
The Atlantic hurricane season is headed into uncharted territory with water temperatures in the Atlantic Ocean and the Gulf of Mexico warmer than they have ever been on record.
(a)Regressed SIOD Index on detrended Sea Surface Temperature (SST) (1958-2007). The western and eastern box used to calculate SIOD Index are indicated. Water temperatures in the southwestern Southern Indian Ocean are significantly higher than water temperature in the eastern part of South Indian Ocean, off Australia.
For example, an increase in the frequency and magnitude of El Niño events have triggered warmer than usual temperatures over the Indian Ocean, by modulating the Walker circulation. [134] This has resulted in a rapid warming of the Indian Ocean, and consequently a weakening of the Asian Monsoon. [135
NEW DELHI (Reuters) -Delhi recorded an all-time high temperature of 52.9 degrees Celsius (127.22 Fahrenheit) on Wednesday as extreme heat conditions gripped the north and western parts of India ...
