  • I think the best we, as

    I think the best we, as common citizens of India, can do is to avoid over-consumption and wastage of India. We must think about the poor farmers every time we waste food this season, and must be mindful in our eating habits. Besides, we must take action to prevent climate change which might accelerate the phenomenon in future.

  • El Nino and La Nina are part

    El Nino and La Nina are part of Southern Oscillation. Southern Oscillation is part of our study when we were students. This is not a new phenomenon. This is a part of 50-70 years [60-year] Pacific Decadal Oscillation. This is a part of hemispheric and regional general circulation patterns. The same is reflected in rainfall, hurricanes and typhoons.

    The WMO Secretary General on WMO Day [23rd March] issued a note on extreme weather events in 2013. In this note they made a statement: 2013 was warm and dry in the Southern Hemisphere nations. This is in association with human actions. Unfortunately, they made this statement casually with analyzing the data at least published information available in the WMO library. During 1970s and 80% I presented analysis of precipitation data from Brazil, South Africa, Botswana and Mozambique. Though they presented different cycles -- 52 to 66 years -- they extrapolated trend -- showed in the publications -- 2013 comes under below the average pattern. Temperature follows wet and dry conditions. Thus 2013 was warm and dry -- you can find this by comparing annual rainfall with annual temperature of India, which I did.

    In the case of 2002, 2004, 2009 only 2002 was El Nino year and 2007 was El Nino year [this was publicized by UN agencies]. Majority of the deficit rainfall El Nino years are part of the below average rainfall 30-year period of 60-year cycle. All the deficit rainfall years are not El Nino years. During the above the average 30 year period of 60-year cycle only 2 to 3 years comes under deficit rainfall years [< 90% of average] and the same during below the average period is around 7 to 10 years.

    Let me give a simple example: What ever may be the condition, when there is a low pressure system, in and around Hyderabad will be dry & warm. This is the general pattern that help the forecasters.

    It is important develop our system of forecasting instead of giving hype to Western reports. Also, develop our water and agriculture systems accordingly. Other-wise it help business interests only.
