PALACIOS-HERNANDEZ, E.; BRITO-CASTILLO, L.; CARRILLO, L.  e  TERESHCHENKO, I.. Interannual deviations of long-term data from observations and contrasting with reanalysis data from the oceanic station at Islas Marías, Nayarit, Mexico. Atmósfera [online]. 2012, vol.25, n.4, pp.355-370. ISSN 0187-6236.

We prepared a synthesis of historical weather conditions for Isla María Madre (1922-1989) to reflect conditions that impact the mainland of México. Observations were compared with regional reanalysis (RR) data in the same area. The results indicate that air temperature, atmospheric pressure, relative humidity, and precipitation in both sources of data display the annual signal. Observations and RR data show differences in climate analysis, mainly in the phase of air temperature and relative humidity. These differences can be explained by the smoothness and the methods used to estimate the RR data.
