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”
River Sand Mining is equivalent to mining not only riparian health, but also destroying massive water storage and recharge capacity. This was one of the central message of the West Zone River Sand Mining Dialogue on Nov 12, 2020 (4-6.30 pm) as part of the India Rivers Week 2020[i] theme “Is Sand Mining Killing our Rivers?” The other central message of the West Zone Dialogue was well encapsulated by this quote from Yamuna Sunny, one of the panelists at the Dialogue: “The intricate relationships between the fishers, the small scale sand miners, the sand farmers, the birds and the trees, pertains not only to possibilities of developing sustainable ways of human life in an economic sense, but also the sustaining of all life forms and their relationships in nature.”Continue reading “West Zone River Sand Mining Dialogue: Mining Riparian Health”
Krishna basin is again facing unprecedented floods, for the second straight year. Unprecedented is a bit of overused word these days, but consider the facts: At no less than ten locations, the Highest Flood Levels (HFL) ever recorded at those locations in the Krishna basin were surpassed (nine locations) or equaled (one location). Some of the HFLs surpassed this year were amazing 56, 51 and 44-year-old records! And imagine most of this happening in second half of Oct 2020, when South West monsoon is traditionally over by end of Sept! There is no doubt the floods were unprecedented.Continue reading “Krishna-Bhima basin floods in Oct 2020 breaks 56-year-old record”
For the past few years, I walk along the bridges and riverbanks of Pune, taking pictures of the unique happenings here. I have made several silent friends who sit at the riverbanks grazing their cattle, or recline on the bridges, looking at the river.

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 “SW Monsoon 2020: District Wise Rainfall”
