Figure 3 shows the spatial pattern of rainfall for the composite of monsoonal drought years (from 1979 to 2015). Most of the parts of India is been deprived from rainfall except eastern part of India. Due to global warming, Indian Ocean is also showing a warming trend, thus the meridional temperature gradient is decreasing across land and sea [33]. As an another fact, premonsoon western disturbances are increasing over northwestern part of Indian and producing increasing western disturbances in pre-monsoon season producing lot more rainfall [24], adding land sea contrast favoring for a weak monsoon start. It has been advocated that the central pacific warming is more vulnerable to produce more drought conditions over India [17]. Some of the recent researches: the call for the influence on the droughts are disruption of the organization of convection [16], soil moisture sensitivity [21], regional ocean impact [18] are suggesting various theories of monsoonal advancement and weak monsoon
