Effects of El Nino Weather

The El Ni?o effects in the Denver Metropolitan welkin ar compared with similar effects in the Los Angeles Basin. personal 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. Comparisons between the effects of the El Ni?o on the two areas were made on the basis the percentage

difference from the averages that characterized the changes in the two measures during the 1982-1983 El Ni?o uttermost.

El Ni?o Effects in Denver and Los Angeles:Precipitation and Temperature

Precipitation and temperature effects of the El Ni?o of 1982-1983 on the Denver Metropolitan land and the Los Angeles Basin are developed for the inclusive period kinsfolk 1982 through August 1983. Precipitation effects (in inches) are presented in chart 1 and temperature effects (in degrees) are presented in graph 2, which may be found on pages 3 and 4 respectively. Precipitation effects (as a percent of the norm) are presented in Chart 3 and temperature effects (as a percent of the norm) are presented in Chart 4, which may be found on pages 5 and 6 respectively.

As the data presented in Chart 1 indicate, The September through December 1982 period was more than wetter than the historic norm in Denver, while the September-October 1982 period in

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

Some analysts contend that the El Ni?o phenomenon may be expected to recur all(prenominal) two years (Kerr, 1993, pp. 656-657). Others, however, believe that the frequency will interchange between four years and seven years. One reading of the 1982-1983 El Ni?o, however, concluded that the effects of a curiously strong ENSO such as that in 1982-1983 influence atmospheric phenomena for a period perhaps as long as 11 years (McPhaden, 1994, pp. 326-327).
