Gallego Ricardo García Emiliano Hernández P. Ribera L. Gimeno Biología Variability angular momentum North Atlantic and Artic oscillations The relative angular momentum (RAM) from 500 hPa to 200 hPa and from 55º N to 90 ºN was computed forthe 1958-1998 period. NCAR-NCEP reanalysis data were used in this study, whose main purpose was to findan annual measurement to compare with the Arctic Oscillation (AO) and the North Atlantic Oscillation(NAO). Annual values of RAM exhibited a clear positive trend consistent with positive trends found in AOand NAO. The correlations between RAM and AO were higher than those between RAM and NAO and thespectral analysis showed a common significant band of oscillation ca. to eight years. 2003 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56516302 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.3 Vol.16 |
