Effects of El Nino Weather Pattern in Denver & L.A.

EFFECTS OF EL NI-O ON DENVER AND LOS ANGELES

This research examines the effects of the El Ni±o weather pattern on the Denver Metropolitan Area and the Los Angeles Basin. The focus of this research is limited to the effects of the 1982-1983 El Ni±o on temperatures and precipitation in the two areas.

El Ni±o is a name given to the periodic oscillation of water temperatures in the southern Pacific ocean (Aceitune, 1992, pp. 483-485). This phenomenon is also referred to as the Southern Oscillation, and by an acronym (ENSO) based upon a combination of the other two terms.

The El Ni±o phenomenon is characterized by a warming of the waters in the Pacific ocean (Kerr, 1993, pp. 656-657). The greater the amount of warning of the Pacific waters that occurs, the more severe are the atmospheric effects. The 1982-1983 El Ni±o was the most severe ENSO to occur over the past four decades.

The typical El Ni±o begins in the late summer or early fall, and the atmospheric effects stemming from the El Ni±o typically begin in the following late winter or early spring (Kerr, 1993, pp. 656-657). The 1982-1983 El Ni±o was unusually in that the ENSO began in April of 1982. As a consequence, the atmospheric effects stemming from the El Ni±o began in the fall of 1982 rather than in the first-half of calendar year 1983.

The direct atmospheric effects of an El Ni±o extend for a period of six months to a year subsequent to the beginning of such effects (Kerr, 1993, pp. 656-657). The direct atmospheric effects of the 1982-1983 El Ni±o began in the fall of 1982 and extended through the late-summer of 1983.

The El Ni±o effects in the Denver Metropolitan Area are compared with similar effects in the Los Angeles Basin. Effects were determined by calculating the differences between precipitation and temperatures during the 1982-1983 El Ni±o and long-term precipitation and temperature averages for the two areas of interest.
