During the recent years, the inter-seasonal and intra-seasonal variability in weather is believed to outsmart the abilities of climatologists and statisticians in defining the limits within which these variabilities can be observed. This has lead the weather experts to realize and convince themselves that the global climate is changing due to enhanced human activities detrimental to natural environment. Therefore, the meteorologists are now required not only to predict weather on short term basis but also climate on long term basis as many critical decisions in agriculture are required to be made well ahead of the season before those weather conditions are realized. Such predictions offer the potential for farmers and other decision makers to predict crop responses to expected climate, and modify decisions to decrease unwanted impacts or take advantages of expected favourable conditions. El Niño is fundamentally a warming of the surface waters of the tropical eastern Pacific Ocean from South American coast to the International Date Line that persists for three or more seasons. El Niño is a pervasive climatic phenomenon which was found to be associated with regional climatic variations throughout the world. Analysis of long term data suggests an inverse relationship between El Niño and southwest monsoon rainfall in India. However, there is no one to one relationship as El Niño years have not always produced severe droughts. Studies on the effect of El Niño either on crop production or productivity at regional level were not so far carried out in India. Not Available |
