The Indian Meteorological Department (IMD) has issued concerning forecast for the upcoming monsoon season, particularly for Andhra Pradesh, where rainfall is expected to fall significantly below normal levels. The monsoon,which typically begins its advance towards the Indian mainland in late May, was delayed this year,only reaching Kerala on June 4,several days later than anticipated. This delay raises alarms about the potential impact on agriculture and water resources in the region.
the overall rainfall for the country is projected at 90% of the Long Period Average (LPA),with an error margin of plus or minus four percentage points. Alarmingly,there is 84% chance of experiencing deficient or below-normal rainfall nationwide. For Andhra Pradesh,the situation is particularly dire,with coastal areas expected to receive less than 91% of their LPA, translating to approximately 547.4 mm of rain against a normal of 601.3 mm. In Rayalaseema, the outlook is even bleaker,with projections indicating below 88% of LPA,or around 358.0 mm compared to a normal of 408.5 mm.
June, critical month for sowing,is expected to be the most deficient, with rainfall anticipated at less than 79% of LPA,or about 86.9 mm against a normal of 94.1 mm. This forecast coincides with rising temperatures across the state,raising concerns about the implications for crop yields and public health.
The IMD has attributed these conditions to the emergence of El Niño, a climate phenomenon characterized by warmer sea surface temperatures in the equatorial Pacific. Bharati Sabade, a scientist at IMD,noted that current data indicates a shift towards El Niño, which typically disrupts monsoon by weakening the trade winds that bring moisture to India. Professor C.V. Naidu from Andhra University elaborated on the mechanics of this phenomenon, explaining that a persistent negative Southern Oscillation Index indicates El Niño conditions,leading to reduced moisture availability.
Despite the grim forecast,Naidu pointed to the Indian Ocean Dipole as a potential mitigating factor. If conditions were favorable, it could help offset some of the expected rainfall deficit. However, current trends do not support this outcome. He also mentioned a weather trough that has recently brought localized rainfall to parts of the state, but emphasized that this is not a solution to broader seasonal deficit.
Looking ahead, the months of July and August will be critical . Naidu warned that if the rainfall deficit continues during this period, crop damage could be severe. Historical data shows that not all El Niño years result in drought for Andhra Pradesh; however, the overlay of global warming complicates predictions. Naidu noted that increased temperatures could lead to more dry days and intense rainfall events,resulting in localized flooding.
The human toll of rising temperatures is already evident,with health issues such as heart problems and dehydration becoming more common. Naidu highlighted the psychological effects of heat,suggesting that increased temperatures can lead to mental health challenges. Urban areas like Visakhapatnam are particularly vulnerable,as poor urban design traps heat and unchecked groundwater extraction threatens local water supplies.
In light of these challenges, Naidu urged practical measures for water conservation,such as planting trees, avoiding excessive paving, and deepening reservoirs. He emphasized the need for careful water usage this year, advising residents to be mindful of their consumption . "If you need a bucket of water for a bath,use only half a bucket," he said,underscoring the urgency of situation.
