Abstract:

An analysis was carried out to study the impact of El-Nino and La-Nina on regional variability of rainfall in Punjab. Data on El-Nino and La-Nina episodes for the period of 41 years (1971-2011) were used for analysing their impact on rainfall variability. During the El-Nino year most of the districts found deficient rainfall ranged between 6 to 47 per cent. During La-Nina episodes a reverse trend in rainfall was observed. El-Nino showed significant association with rainfall but in case of La-Nina episode non-significant association was observed with rainfall. Regional rainfall was more affected by El-Nino episodes as compared to the La-Nina episodes. These episodes had no significant impact on rice productivity because of artificial source of tube well irrigation.
