The role of El Niño southern oscillation (ENSO) on variations of monthly Plasmodium falciparum malaria cases at the cayenne general hospital, 1996-2009, French Guiana

Malaria Journal, 2011
Background Malaria remains a serious problem in French Guiana, which is at potential risk for drought linked with the El Niño Event and where there could be a risk of malaria epidemic after the onset of an El Niño event.

On Sub-ENSO Variability [PDF]

, 2006
Multichannel singular spectrum analysis (MSSA) of surface zonal wind, sea surface temperature (SST), 20° isotherm depth, and surface zonal current observations (between 1990 and 2004) identifies three coupled ocean–atmosphere modes of variability in the ...

Assessing Past and Future Temperature‐ and Precipitation‐Based Indicators in the Republic of Yemen

International Journal of Climatology, EarlyView.
For the first time in the literature, this work assesses the past and future climatic trends over Yemen, a highly vulnerable country for which science‐based, high‐quality information for the development of climate change adaptation plans was not available until now.

Large Proportions of Surface Ozone and Premature Mortality Due to a Stratospheric Intrusion Event in North China

International Journal of Climatology, EarlyView.
This study, by examining a typical stratospheric intrusion event that occurred in North China from 30 to 31 July 2021, found that the event led to a sharp increase in near‐surface ozone concentrations by 23 ppbv within 36 h, accounting for 40% of the total observed ozone levels, with localised peaks exceeding 30 ppbv.

Persistent El Niño-like conditions over the western Pacific during the Bølling–Allerød interstadial

Communications Earth & Environment
Projecting El Niño-Southern Oscillation responses to future climate change are hindered by limited paleoclimate records spanning past abrupt climate transitions.

Separating and quantifying the distinct impacts of El Niño and sudden stratospheric warmings on North Atlantic and Eurasian wintertime climate

Atmospheric Science Letters, 2019
Sudden stratospheric warmings (SSWs) significantly influence Eurasian wintertime climate. The El Niño phase of the El Niño–Southern Oscillation (ENSO) also affects climate in that region through tropospheric and stratospheric pathways, including ...

Potential of Equatorial Atlantic Variability to Enhance El Nino Prediction [PDF]

, 2013
Extraordinarily strong El Niño events, such as those of 1982/83 and 1997/98, have been poorly predicted by operational seasonal forecasts made before boreal spring, despite significant advances in understanding, improved models, and enhanced ...

Dry‐Season Water Deficits in the Southwestern Amazon Under High Emissions

International Journal of Climatology, EarlyView.
Projected climatic water deficit in the study region indicates a longer and more intense dry season, with delays in the onset of the wet season under higher emission scenarios. These changes, particularly, pronounced under SSP5‐8.5, suggest increased ecological vulnerability and greater seasonal water stress.

Contrasting climate oscillations impacts on phytoplankton in the western and eastern tropical Pacific

Nature Communications
Climate oscillations like the El Niño-Southern Oscillation and Pacific Decadal Oscillation significantly impact marine ecosystems. Traditionally, warm events are thought to suppress nutrient availability, reduce phytoplankton biomass, and change ...

Relevance of Relative Sea Surface Temperature for Tropical Rainfall Interannual Variability

Geophysical Research Letters, 2020
The coupling between sea surface temperature (SST) anomalies and rainfall is an important driver of tropical climate variability. Observations however reveal inconsistencies, such as decreased convective rainfall in regions with positive SST anomalies in
