The below-normal rainfall in East and Northeast India has already affected the ongoing paddy sowing operations in the Indo-Gangetic plain, which are kharif (summer sown) crops as compared to the area sown for the same period last year. pulling down the total area of.
However, “above normal” rainfall is expected in August over most parts of southeast India, northwest India (including Delhi-NCR) and adjoining west-central India. Although the country received 8% more cumulative rainfall in July after recording an 8% deficit in June, eastern and northeastern India recorded the lowest rainfall in July in 122 years. The country’s July rainfall was 17% above the long period average, the highest since 2005.
IMD Director General M Mohapatra, while issuing a Meteorological Department release, said, “The rainfall over the entire country is likely to be normal (94 to 106% of the Long Period Average (LPA)) during the second half of the southwest monsoon season. ” The LPA of rainfall over the country during the period August to September based on the latest forecast 1971-2020 data is 422.8 mm.
Referring to the situation in East and Northeast India, Mohapatra said that during August-September, intense rainfall deficiency is likely to persist over Bihar and some other parts of Indo-Gangetic plains and northeastern states, while Jharkhand, East The shortfall is likely to decrease. Uttar Pradesh and parts of Gangetic West Bengal.
The spatial distribution of the probabilistic forecasts for the tertile ranges of rainfall (above normal, normal and below normal) during August and September suggests that above normal rainfall is expected to occur over most parts of South India (except the west coast). is likely to. West Central India and North West India.
Northwest India may see normal rains in August and this will boost the sowing operations of Kharif crops in this part of the country. Paddy sowing remains a matter of concern mainly due to sluggish rains in the Indo-Gangetic plains including Uttar Pradesh, Bihar and West Bengal.
Area data released by the agriculture ministry last Friday showed that the area under paddy sown stood at 231 lakh hectare (LH) on July 29, up from 267 lakh hectare during the same period last year – 36 lakh hectare (LH). 13%) reduction.
Whereas Punjab has already recorded more area under paddy than last year. Haryana has almost bridged the gap which was high till mid-July. The total present deficit of about 36 lakh hectare in paddy area is mainly attributed to the high difference in West Bengal, Uttar Pradesh, Bihar and Jharkhand.
On temperature, the IMD predicted “above normal maximum temperatures” – i.e. warmer than normal temperatures – over many parts of east central, east and northeast India and parts of northwest and south interior peninsular India during August. It said the rest of the country is likely to see “normal to below normal maximum temperatures”.
On the other hand, “above normal minimum (night) temperatures” are very likely to prevail over some parts of east central, east, northeast and hilly regions of northwest India. “Below normal minimum temperatures are likely over many parts of Northwest, West Central and South India,” the Meteorological Department said. This means that the nights in these parts of the country will be normal or relatively less warm.
