According to India Meteorological Department (IMD), during the just concluded Post Monsoon Rainfall for 2020, that included rainfall during Oct-Dec months, India received 124.6 mm rainfall, 0.64% above the normal rainfall of 123.8 mm during the period. As per IMD[i] definition, the rainfall was thus normal.
This three-month period from Oct 1, to Dec 31 includes the North East Monsoon that mainly affects parts of South India including Tamil Nadu, Puducherry, Rayalseema, parts of Karnataka and Kerala. IMD declared on Jan 1, 2021 that the of NE Monsoon ended on Dec 31, 2020 with normal overall rainfall: TN had 6% above normal, Karnatak 13% above normal, Puducherry 32% above normal, Andhra Pradesh 33% above normal. However, Lakshadweep had 9% below normal and Kerala 26% below normal. This monsoon provides 48% of the annual rainfall of TN so it is most imp for that state.
The rainfall revived only towards the end of November, mainly due to two consecutive cyclones — Nivar and Burevi — both of which developed in the Bay of Bengal. While Cyclone Nivar crossed the coast close to Karaikal near Puducherry and brought heavy showers for the east and coastal districts of Tamil Nadu, Cyclone Burevi weakened before it reached land.Continue reading “Post Monsoon 2020: State wise Rainfall”
Four different news on River Sand Mining catch our eye, with common underlying theme of NEXUS of government and miners on the one hand and IMPUNITY of the sand miners in indulging in mindless violence. In Madhya Pradesh and Uttar Pradesh, no less than the Supreme Court (SC) and National Green Tribunal (NGT) respectively expose nexus between the state government and illegal sand mining. In Agra (UP again) the sand miners have again shown impunity in attempting to crush the forest officials trying to stop incessant illegal river sand mining from Yamuna River, they managed to run away, as usual. In Tamil Nadu, the High Court has appointed an advocate to ascertain the extent of illegal mining.
On any day, and in any sector, this should have been seen as eye widening affairs. It indeed should. But in sand mining this seems like regular dog biting man kind of news. One hopes it is not and that serious consequences follow. Kind of consequences that would not only help bring commensurate punishment to those responsible, but before that the identification of the guilty. And that punishment will be exemplary enough to bring some fear into the sand miners and those indulging in corruption in sand mining. It’s a bit tall order, but not unwarranted.Continue reading “DRP NB 7 Dec 2020: Courts expose NEXUS and IMPUNITY in Sand Mining. Will any commensurate consequences follow?”
One of the central themes of the lively presentations and discussion at the South India Sand Mining Dialogue was that the grain of sand is a habitat for so many lives, as so brilliantly put forward by Munmun Dhalaria, one of the panelists. Another key highlight was that Yogeshwaran, the lawyer painfully noted that sand mining laws are neither environment friendly nor people friendly and can be environment friendly only if they are people friendly.Continue reading “South Zone Sand Mining Dialogue: The grain of sand is habitat for many lives”

Kerala continues to witness unusual monsoon rainfall patterns for the third straight year in 2020. Kerala had witnessed its worst flood in almost a century in 2018. The 2019 flood was probably second only to the 2018 floods over the last 50 years, with many places experiencing larger floods than that in 2018. While the state did not face huge floods this year, tragedy struck in the form of the Pettimudi landslide near Munnar in Idukki district. It buried alive 70 members of plantation labourer families, making it the worst ever landslide in Kerala in terms of human causality. Kerala has also witnessed its wettest monsoon in September in this millennium with a rainfall of 601 mm, surpassing the previous highest of 526 mm recorded in 2007. The S-W monsoon period is now over and the state received 2227 mm rainfall, which is 9 percent above long term average.Continue reading “Reservoir Operations Fail People in Chalakudy River Basin in Kerala in 2020”
India received 957.6 mm rainfall in Just concluded South West Monsoon 2020, during the scheduled 4 month monsoon from June 1 to Sept 30, 2020. This is 8.74% above normal monsoon rainfall of 880.6 as per India Meteorological Department (IMD). This is considered ABOVE NORMAL rainfall, since rainfall is in the range 4-10% above Normal rainfall. This sounds good at national level, but the situation on ground could be very different, if we see the rainfall across the country.
It is noteworthy as per even IMD, monsoon has not yet withdrawn from most parts of the country. But IMD closes its monsoon rainfall account at 0830 hours on Sept 30, so all rainfall after that hour has to be counted in “Post Monsoon” rainfall book, even though the rainfall is very much part of monsoon as per IMD.Continue reading “Monsoon 2020: District Wise Rainfall”
During the just concluded first half of the South West Monsoon 2020, India received 453.3 mm rainfall, just 1.1 mm above the normal rainfall of 452.2 mm during the period. The Surplus of 18% rainfall that India received in June 2020 has thus been wiped out by the 9.9% deficit in July rainfall. Normal rainfall in July 2020 is 285.3 mm, while actual rainfall was 257.1 mm. IMD does not provide monthly figures of rainfall for different states, sub divisions and river basins, which it should along with comparison with respect to normal rainfall and rainfall last year.
To get July 2020 rainfall, we will need to use the figures given in this article along with the figures of June 2020 rainfall (see: https://sandrp.in/2020/06/30/district-wise-rainfall-in-india-in-june-2020/). The district wise figures of June-July 2020 rainfall can be seen in this PDF file from IMD: IMD DISTRICT WISE RAINFALL FROM JUNE 1 TO JULY 31 2020.
