Indian Ocean Dipole
The Indian Ocean Dipole (IOD) also known as the Indian Nino is an irregular oscillation of sea-surface temperatures in which the western Indian Ocean becomes alternately warmer and then colder than the eastern part of the ocean.
The IOD involves an aperiodic oscillation of sea-surface temperatures, between "positive", "neutral" and "negative" phases. A positive phase sees greater-than-average sea-surface temperatures and greater precipitation in the western Indian Ocean region, with a corresponding cooling of waters in the eastern Indian Ocean—which tends to cause droughts in adjacent land areas of Indonesia and Australia. The negative phase of the IOD brings about the opposite conditions, with warmer water and greater precipitation in the eastern Indian Ocean, and cooler and drier conditions in the west.
The IOD also affects the strength of monsoons over the Indian subcontinent. A significant positive IOD occurred in 1997-8, with another in 2006. The IOD is one aspect of the general cycle of global climate, interacting with similar phenomena like the El Niño-Southern Oscillation (ENSO) in the Pacific Ocean.

‘An epic expanse of golden sand’: the sweeping appeal of North Devon
The Observer | 20 Apr 2025For so many years Devon was viewed as the poorer relation to Cornwall; its coastline less rugged and epic, its beaches smaller, less elemental. For us, the county was always just a cut-through to the treasure beyond and never a destination in itself. The fact that Cornwall was much further to get to somehow proved its remoter...
