Students will explore the role of the ocean as part of the El Nino Southern Oscillation (ENSO).
The El Nino Southern Oscillation and the historic malaria epidemics on the Indian subcontinent and Sri Lanka: An early warning system.
The El Nino Southern Oscillation (ENSO, i.e., El Nino / La Nina) in the Pacific recurs over a period of 3 to 8 years and can significantly modulate Atlantic Ocean activity owing to its effects on vertical wind shear in the atmosphere.
The performance of monsoon depends much on how global meteorological parameters such as El Nino Southern Oscillation ( ENSO) unfold in the weeks to come.
In addition, the scientists say global warming will have greater impacts than previously thought on the El Nino Southern Oscillation, a tropical phenomenon that has global impact on climate and food production.
The two most significant synoptic forcings [thus] affecting the surface climatic elements of Borneo are the monsoon and the El Nino Southern Oscillation [ENSO], which are mutually interactive.
Enso represents the El Nino Southern Oscillation, the well-known cycle that results in moisture-laden Pacific trade winds blowing from South America towards Australia (La Nina) in some years, with the reverse (El Nino) causing drought in Australia at other times.
In a natural way, with an irregular periodicity between two and seven years, a warming of the South Pacific takes place, generating the event of "El Nino Southern Oscillation" (ENSO), usually followed by a cooling that leads to "La Nina".
Cross-correlation and Poisson regression analyses showed that rainfall, land surface temperature, relative humidity, and the multivariate El Nino Southern Oscillation index were significantly associated with monthly HFRS cases with lags of (3-5) months.
Occurring in August and September, these are the speed of trade winds over the tropical North Atlantic, sea temperatures in the tropical North Atlantic, and the sign and strength of El Nino Southern Oscillation. US landfalling hurricane activity is influenced by the level of hurricane activity occurring at sea, the pre-season North Atlantic Oscillation, and by July tropospheric wind patterns over the North Atlantic and US," AON said.
