Monitoring of Climatological Variability Using EOS and OSMl Data

  • Published : 2003.06.01

Abstract

Dramatic changes in the patterns of satellite-derived pigment concentrations, sea-level height anomaly, sea surface temperature anomaly, and zonal wind anomaly are observed during the 1997-1998 El Ni$\bar{n}$o. By some measures, the 1997-1998 El Ni$\bar{n}$o was the strongest one of the 20$^{th}$ century. A very strong El Ni$\bar{n}$o developed during 1997 and matured late in the year. A dramatic recovery occurred in mid-1998 and led to La Nina condition. The largest spatial extent of the phytoplankton bloom was fellowed recovery from El Ni$\bar{n}$o over the equatorial Pacific. The evolution towards a warm episode (El Ni$\bar{n}$o) started from spring of 2002 and continued during January 2003, while equatorial SSTA remained greater than +1$^{\circ}C$ in the central equatorial Pacific. The OSMI (Ocean Scanning Multispectral Imager) data are used for detection of dramatic changes in the patterns of pigment concentration during next El Ni$\bar{n}$o.
