Abstract

The inf luence of the ENSO condition in the frequency and intensity of rainfall events in the physiographic province Baja California Peninsula was analysed as a historical series of 15 years of daily rainfall records TRMM. The database was stratified into seven categories at intervals of 5 mm; the extreme events considered as > 30 mm day-1. We gathered evidence that, the ENSO condition inf luences the frequency and intensity of rainfall events. We also observed a certain symmetry between the conditions ENSO-neutral and ENSO-week La Niña and ENSO-weak El Niño with ENSO-moderate La Niña, causing an increase in the frequency of rain events and a decrease, respectively. Regarding the intensity of the rain, other symmetrical relations were between the condition ENSO-neutral and ENSO-weak El Niño and asymmetrical between the conditions ENSO-moderate La Niña and ENSO-Strong La Niña. The rainfall intensity was higher during the conditions Neutral and Weak El Niño and lower during the conditions Moderate La Niña and Strong La Niña. These results are important because changes in the frequency and intensity of extreme events are the most dramatic consequence of climate variability, directly affecting the functioning of ecosystems, their landscape formation and spatial boundaries of the land use. The relationship between the frequency of occurrence and intensity of extreme events, the ENSO condition and the presence of hurricanes is still under investigation.
