Secondo l'IMD, le piogge di settembre saranno al di sotto del normale
Il Dipartimento meteorologico indiano (IMD) ha previsto che l'India sperimenterà piogge al di sotto della norma nel settembre 2026, con livelli di precipitazione che dovrebbero essere almeno il 9% inferiori alla media di lungo periodo di 167,9 mm. Questa previsione segue un agosto asciutto, che ha visto il paese ricevere 213,3 mm di pioggia, il settimo più basso dal 2001, e temperature elevate record. L'IMD attribuisce questa tendenza alle condizioni di El Niño in corso, che contribuiscono a temperature più elevate e riduzione dell'umidità atmosferica. Mentre alcune regioni come il nord-ovest, il nord-est e parti dell'India centrale e orientale potrebbero vedere piogge normali o superiori alla norma, altre aree, in particolare l'est e il nord-est, affrontano deficit significativi. Il dipartimento osserva anche che frequenti sistemi di bassa pressione e le perturbazioni occidentali hanno influenzato le piogge, concentrandosi in regioni specifiche piuttosto che fornire sollievo diffuso da El Niño.
India is bracing for below-normal rainfall in September, marking the final month of the monsoon season, according to forecasts released by the India Meteorological Department (IMD). This prediction indicates that the overall monsoon season will conclude with a rainfall deficit, following an already challenging period marked by the warmest August since 1901. The IMD noted that the mean temperature for August reached 28.01°C, surpassing the long period average (LPA) by 0.67°C. The forecast highlights that September rainfall is expected to be at least 9% below the LPA of 167.9 mm, which is crucial for the kharif crop cycle. Despite some regions experiencing normal to above-normal rainfall, such as parts of the northwest, northeast, east, east-central India, and isolated areas of southeast peninsular India, the majority of the country is anticipated to see below-average precipitation. This uneven distribution threatens agricultural productivity, potentially leading to reduced yields and output for key crops like pulses, coarse grains, oilseeds, maize, rice, and cotton. As of August 31, the cumulative monsoon rainfall deficit stands at 14%, with the situation deteriorating further into September. The IMD's director general, M Mohapatra, attributed the current weather patterns to the presence of strong El Niño conditions, which are expected to intensify through November and December. These conditions contribute to higher-than-normal temperatures across most parts of the country, exacerbating the challenges faced by farmers who rely heavily on timely and adequate rainfall. The impact of these climatic conditions extends beyond immediate agricultural concerns. With the sowing of most seasonal crops nearing completion, the lack of sufficient rainfall in September could result in increased input costs for farmers, necessitating greater expenditure on irrigation for existing crops. The IMD's forecast underscores the need for adaptive strategies among agricultural stakeholders to mitigate potential losses. The IMD's analysis reveals that while certain areas experienced significant rainfall, particularly in the Indo-Gangetic Plain, other regions, especially the western coast and Punjab, faced a dearth of precipitation. This disparity in rainfall distribution complicates efforts to ensure uniform growth across different agricultural zones. The interaction of frequent Western Disturbances with monsoon circulation has further concentrated rainfall in specific regions, failing to provide relief to broader areas affected by drought-like conditions. Looking ahead, the continuation of El Niño conditions suggests that the adverse effects on rainfall patterns will persist, influencing both the immediate agricultural calendar and long-term climate planning. As the monsoon season draws to a close, the focus shifts towards assessing the implications of these forecasts on food security and economic stability, setting the stage for critical decisions regarding resource allocation and policy adjustments in the coming months.
