Brief Report on Extremely Heavy Rainfall Events over Tamil

Brief Report on Extremely Heavy Rainfall Events over Tamil Nadu

(1-15 Jan 2021)

1. Introduction

Northeast monsoon (NEM) season comprising of the months from October to December is the

major rainfall season for Tamilnadu & Puduchery& Karaikkal. The normal rainfall for the

subdivision for this period is 44cm. About 45% of the annual rainfall of this subdivision (about

60% for coastal regions) is accounted by the rainfall during this period. Though the NEM

seasonal rainfall normally end by the last week of December, there were years in which NEM

rainfall spill into January of the next year. In 2021, the NEM rainfall extended into the month of

January with 133.9mm till 15th January against the normal of 11.4mm for the period with 1074%

departure from normal . The salient features of this event are discussed below.

The subdivision has experienced a wet spell of about 11 days during the first fortnight of January

2021, especially during 5-15 Jan 2021. If the cumulative rainfall for twenty four hours is

considered , there had been two spells of peak rainfall activity; one during 5-7 January in the

districts of Chennai, Kanchipuram, Chengalpattu, Ariyalur, Tiruvarur, Coimbatore, Cuddalore,

Dharmapuri, Dindigul and Kallakurchi and another during 11-13 Jan in the extreme southern

districts of Thanjavur, Tirunivali and Toothukudi.

Figures 1 to Figure 4 shows the weekly rainfall map for the week ending on 30th December 2020,

6 January 2021, 13th January 2021 and 20th January 2021 for the country as a whole.

It is observed that, during the week ending on 30th December 2020, the percentage departure of

realized rainfall over the subdivision had been -91%. However during the week ending on 6th, 13th

and 20th January 2021, it has become 807%, 1036 and 727 % respectively which accounted the

intense rainfall activity during the first fortnight of the month experienced by the sub division. The

realized weekly rainfall of Tamil Nadu, Puducherry & Karaikkal had been 1.0 , 39.9, 76.1 and

28.9 mms against the normal of 10.7, 4.4, 6.7 and 3.5 mms for the week ending on 30th Dec

2020, 6th, 13th and 20th January 2021 respectively.

During the NEM -2020 periods, the subdivision received 6% above normal rainfall (Figure 5)

Figure 5: Rainfall over Tamil Nadu, Puducherry & Karaikkal during NEM2020

However, during the short period of 1-15 Jan 2021 , the subdivision received 133.9 mm against

the normal of 11.4mm which is about 1074% departure from normal ( Figure 6 ) .

Figure 6: Rainfall over Tamil Nadu, Puducherry & Karaikkal during 1-15 Jan 2021

The daily rainfall for the period from 1-16 January 2021 for Tamil Nadu, Puducherry & Karaikkal

are given in Annexure I.

2. Main Synoptic Features

Generally the main synoptic systems during NEM season are Low pressure systems like

depressions, cyclones and westward moving easterly waves. It is noted that during 1-15 January

2021, the frequent westward moving easterly waves in the form of troughs and cyclonic

circulations caused large excess rainfall as mentioned earlier. Figure7 & Figure 8 show that the

easterlies were stronger and the perceptible water content were more than normal over south

peninsular region during 1-15, Jan 2021.

Figure 7: Zonal wind Composite Anomally (850 hPa) , 1-15 Jan 2021

Figure 8: Precipitable Water Content Composite Anomally, 1-15 Jan 2021

The synoptic features during the period from 1 to 5 January, 6 to 10 January and 11 to 15

January along with rainfall distribution are discussed below.

1 to 5 January 2021

Moderate easterlies/north-easterlies prevailed over the region in lower tropospheric levels.

During this period the sub division received 25.5 mm against the normal of 3.0mm rainfall which

is about 748% above normal. About 7 stations received heavy rainfall and significant no. of

stations received rainfall between 2 to 4cm. The district rainfall distribution is shown in Figure 9.

3.

Figure 9: District rainfall Distribution, 1-5 January 2021

6 to 10 Jan.

During this period, there were low level easterlies with embedded trough extending up to 1.5 km

above mean sea level from south Sri Lanka coast to north Coastal Andhra Pradesh which moved

westwards across Comorin area to Southeast Arabian sea. Also a cyclonic circulation lay over

Equatorial Indian Ocean and adjoining central parts of South Bay of Bengal and extended upto

3.1 km above mean sea level. At the end of this period the sub divisional seasonal rainfall

increased to 751% of the normal.

About 14 stations received very heavy rainfall, 25 stations received heavy rainfall and significant

no. of stations received rainfall between 2 to 4cm. The district rainfall distribution at the end of

this period is shown in Figure 10.


11 to 15 Jan.

During this period, a cyclonic circulation extending upto 3.1 km above mean sea level lay

over Equatorial Indian Ocean & adjoining central parts of South Bay of Bengal which moved

progressively westwards towards Southeast Arabian Sea across Comorin and Maldives area

and neighborhood. During this period, about two stations received extremely heavy Rainfall

on 13.1.2021 (Parangipettai (Cuddalore District): 28, Sethiyathope (Cuddalore District): 21).

12 stations received very heavy rainfall, 50 incidences of heavy rainfall and significant no. of

stations received rainfall between 2 to 4cm .The district rainfall distributions for the period is

shown in Figure 11.


In addition to the above mentioned intense rainfall occurrences, fairly widespread to widespread

rainfall activity with rainfall amounts ranging from 1 cm to 5 cm occurred over several districts. It

is to be mentioned that the normal rainfall for the period itself are very low and are of the order of

few mm for these districts thus making the percentage departure of the realized rainfall very high.

3. Impact on Agriculture

The above mentioned large excess rainfall during the first fortnight of January 2021 in Tamil

Nadu caused damages to various crops especially the lowland rice in Cauvery Deltaic areas and

also the pulse crops in southern districts of the State.

Most of the crops, especially Samba rice crop at harvesting stage in Thiruvarur,

Thirunelveli, Nagapattinum, Cuddalore, Thanjavur, Ramanathapuram, Ariyalur, Pudukkottai,

Dindigul, Sivagangai, Chengalpattu, Tuticorin and Perambalur districts got submerged in rain

water and the farmers could not harvest the crop. The grains got germinated in the field itself,

leading to huge loss for the farming community. Maize crop in these districts also got affected

and the quality of harvested maize grins is also reduced. In some of the fields, even maize grain

got germinated hence cannot be used even for poultry industry or as fodder. Waterlogging and

lodging of crops at maturity stage also have been observed in many fields.

In Karaikkal region (Puducherry) around 4500 hectares of Paddy are under cultivation in

this Rabi season which is nearing harvesting stage. These crops were damaged due to weight of

panicle, wind velocity and standing water.

In southern districts like Ramanathapuram, Tuticorin, Virudhunagar and Thirunelveli,

pulse crops like black gram have been affected at harvesting stage. Drainage facilities could not

be provided due to continuous rainfall and overflow of all channels. Here, the soil is also of clay

texture where agricultural operations are difficult to carry out at rainy conditions.

Continuous rainfall situation hampered agricultural operations including harvesting

operations.

The Agricultural Advisory Service bulletins issued by concerned Agro Met Field Units

(AMFUs) and District Agro Meteorological Units (DAMUs) also indicate that, drainage

facilities and postponing of agricultural operations were advised to the farmers during the

period. However, it is understood that since the river Cauvery had been flowing over its

capacity level and the canals/ channels were running at full capacity, despite getting

informed about the forecast, farmers could not drain the water from the fields.

4. Forecasts and Warnings

As per practice, forecasts and warnings are issued for five days with an outlook for another two

days. From National Weather Forecasting Centre (NWFC) New Delhi, the forecasts are issued

in subdivisional scale whereas from the Regional Weather Forecasting Centers (RWFCs) and

State Weather Forecasting Centres(SWFCs) forecasts and warning are issued in the district

scale for their corresponding areas of responsibility.

Forecasts and Warnings issued from NWFC

As mentioned above, NWFC issue forecast and warning for the subdivision Tamil Nadu,

Puducherry & Karaikkal as a whole. The five days’ forecasts and warnings issued by NWFC for

the first fortnight of January 2021 are given in Table 2 and Table 3 respectively.

From the table it is clear that, the wet spell in respect of spatial distribution and intensity of rainfall

had been covered in the forecasts and warnings.

5. Nowcast

NWFC issues nowcast guidance on daily basis for the expected occurrence of severe weather

over different parts of the country. Based on this guidance, the RWFCs/SWFCs keep monitoring

the development of severe weather in their area of responsibility and issue nowcasts as and

when required.

The nowcast guidance for Tamil Nadu, Puducherry & Karaikkal issued from NWFC during 1-15

January 2021 is given in Table 7.

Table 7: Nowcast warning Guidance issued from NWFC, New Delhi for Tamilnadu,

Puducherry & Karaikal during 1-15 January 2021

RWFC Chennai has issued nowcasts for thunderstorm and associated weather phenomena and

for intense rainfall activity accordingly and has disseminated the same to the users through all

possible means including social media even in regional language.

5. Agricultural Meteorological Services

Under GraminKrishi Mausam Seva(GKMS), eight Agromet Field Units (AMFUs) and ten

District Agromet Units (DAMUs) under Tamil Nadu Agricultural University (TNAU), Tamil Nadu

Veterinary & Animal Sciences University (TANUVAS) and M.S. Swaminathan Research

Foundation cater to the weather needs of farmers in Tamil Nadu. In the U.T. of Puducherry,

AMFU, Karaikal is serving the farmers in Puducherry and Karaikalregion.

Agromet advisories related to the intense rainfall event were issued to the farmers

through SMS using mKisan Portal, mobile Apps (MeghDoot and State Govt. App) and also

through WhatsApp for the event.

During the above mentioned rainfall scenario, agromet advisories have been communicated to

the farmers for rice, pulses, vegetables and other field crops and also for livestock through SMS,

WhatsApp, MeghDoot, State Govt App and also by the private companies under PPP mode.

Agromet advisories have been communicated to around 12.17 lakh farmers and detailed
