Efecto de la condición ENSO en la frecuencia e intensidad de los eventos de lluvia en la península de Baja California (1998-2012)* Effect of the ENSO condition in the frequency and intensity of rainfall events in the Baja California peninsula (1998-2012)

The influence 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 influences the frequency and intensity of rainfall events. We also observed a certain symmetry between the conditions ENSO-neutral and ENSO-week La Nina and ENSO-weak El Nino with ENSO-moderate La Nina, 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 Nino and asymmetrical between the conditions ENSO-moderate La Nina and ENSO-Strong La Nina. The rainfall intensity was higher during the conditions Neutral and Weak El Nino and lower during the conditions Moderate La Nina and Strong La Nina. These results are important because changes in the frequency
