KLAUS, Dieter; POTH, Andreas; VOSS, M.  e  JAUREGUI, Ernesto. Ozone distributions in Mexico City using principal component analysis and its relation to meteorological parameters. Atmósfera [online]. 2001, vol.14, n.4, pp.171-188. ISSN 0187-6236.

A description is made of ozone patterns as related to some meteorological variables (temperature, surface wind direction, speed, and global radiation). The observations are expressed in terms of eigenvectors and their associated coefficients in order to determine the gross features of the ozone city-wide patterns. By using concurrent 700 hPa prevailing upper winds and the observed converging surface winds induced by local and regional currents it was possible to provide a physical explanation for some characteristic ozone distributions observed in the MCMA. The present study attempts to provide additional basis to the knowledge of relationships between ozone distributions and meteorological parameters in the Mexico Basin.
