Asymmetry and Diversity in the pattern, amplitude and duration of El Niño and La Niña
Years of record
- N/A
El Niño and La Niña, the two phases of ENSO, are sometimes described as opposites. However, there are asymmetries in their spatial structure, amplitude, duration and seasonal evolution. This leads to differing teleconnections and global impacts, as well as implications for ENSO predictability. The 'Expert Guidance' section of this post summarizes the metrics used to…

Coral geochemical records: An overview of their use as climate proxies and of available databases
Years of record
- N/A
Coral records are one of the main types of high-resolution (annual to sub-annual) paleoclimate proxies, providing timeseries of environmental conditions reaching hundreds to thousands of years into the past in the tropics, the central driver of the global atmospheric circulation. As such, corals complement paleoclimate records from the largely mid-latitude tree-…

Nino SST Indices (Nino 1+2, 3, 3.4, 4; ONI and TNI)
Years of record
- to
There are several indices used to monitor the tropical Pacific, all of which are based on sea surface temperature (SST) anomalies averaged across a given region. Usually the anomalies are computed relative to a base period of 30 years. The Niño 3.4 index and the Oceanic Niño Index (ONI) are the most commonly used indices to define El Niño and La…

QBO: Quasi-Biennial Oscillation
Years of record
- to
The quasi-biennial oscillation (QBO) is a quasi-periodic oscillation of the equatorial zonal wind between easterlies and westerlies in the tropical stratosphere with a mean period of 28 to 29 months. The alternating wind regimes develop at the top of the lower stratosphere and propagate downwards at about 1 km (0.6 mi) per month until they are dissipated at the tropical…

Southern Oscillation Indices: Signal, Noise and Tahiti/Darwin SLP (SOI)
Years of record
- to
The Southern Oscillation Index (SOI) is a time series used to characterize the large scale sea level pressure (SLP) patterns in the tropical Pacific. Monthly mean SLP at Tahiti [T] and Darwin [D] are used. An optimal SOI can be constructed. It consists of [T-D] which is a measure of the large scale phenomena while [T+D] is a measure of small scale and/or…

The Tropical Rainfall Measuring Mission (TRMM) is a joint space mission between NASA and Japan's National Space Development Agency designed to monitor and study tropical and subtropical precipitation and the associated release of energy. The mission uses 5 instruments: Precipitation Radar (PR), TRMM Microwave Imager (TMI), Visible Infrared Scanner (VIRS), Clouds &…

Tropical Moored Buoy System: TAO, TRITON, PIRATA, RAMA (TOGA)
Years of record
- to
The Tropical Ocean Global Atmosphere program (TOGA) is a component of the World Climate Research Programme (WCRP) aimed specifically at the prediction of climate phenomena on time scales of months to years. In order to achieve the TOGA goals, a strategy of large-scale, long-term monitoring of the upper ocean and the atmosphere has been developed. In particular, several…
