Effect of the equatorial Pacific upwelling on atmospheric CO2 during the 1982-1983 El Nino

Research output: Contribution to journalArticle

Abstract

During this strong El Nino event, additional sinks for atmospheric CO2 operated. By late 1983, the growth rate rebounded to above average, indicating the presence of new sources. In this study, box models of the ocean-atmosphere carbon cycle are used to isolate and estimate the effects of the collapse and return of the upwelling in the equatorial Pacific during an El Nino. The models capture the major trends during the El Nino for sea surface temperature, nutrients, and ΔpCO2. The drop in ΔpCO2 in the normally strong source of the equatorial Pacific can account for a partial amount (probably less than 30%) of the decrease in the growth rate in atmospheric CO2 centered around late 1982. -from Author
