Salient Features

Monsoon advanced in Haryana this year on 1st July near its normal onset

time and covered Haryana on 3rd

June 2008 and latest is 27th

July 1987.

State received 200.1 mm of rainfall (June-September) against 460.3 mm of it

Long Period Average (LPA) with overall deficit of 56.5% making it below

normal monsoon in Haryana as predicted by IMD in its Long Range forecast

issued on 4th April and updated in June and August 2014 respectively.

This was fifth meteorological drought (rainfall less than 75% of LPA) in last

10 years in Haryana and was third lowest rainfall monsoon year in last 113

years (1901-2014). Lowest rainfall in Haryana was in year 1987 when overall

deficit was 64%.

Rainfall deficit in June, July, August and September was 42.9, 56, 79.8 and

15.5% of LPA respectively.

Out of 21 districts in Haryana wherein rainfall was reported during

Monsoon, 2014, 11 districts received scanty rainfall and 10 districts received

deficient rainfall.

Out of 74 tehsils in Haryana rainfall for 69 tehsils was reported and it was

normal in 2, deficit in 20 and scanty in 47 tehsils respectively.

Monsoon seasonal rainfall (June – September) was 88% of LPA for country

as a whole and 79% of LPA for NW India and 43% of LPA in Haryana.

IMD operational forecast for monsoon 2014 issued in April and updated in

the month of June and August 2014 for the country as a whole and for NW

India was within the limit of forecast issued by IMD in August 2014 but was

overestimated for Haryana.

1. Onset and advance of Monsoon 2014

This year monsoon set in Kerala on five days after the normal onset date.

Monsoon also advanced most parts of south Arabian Sea, some parts of

Tamilnandu, most parts of West Central southwest Bay of Bengal on same day. It

further advanced central Arabian Sea, South Gujarat entire Kokan & Goa, some

parts of South Peninsula, Odisha, Jharkhand and Bihar, entire NE states and most

parts of Gangetic West Bengal by 18th June. It further advanced in most parts of

South Peninsula east and adjoining parts of Central India by 20th June. Monsoon

remained in weak phase for next about 10 days. Subsequently a favorable

interaction of monsoonal flow with mid latitude westerlies gave further impetus for

advancement of southwest monsoon in Western Himalayan region and plain of

NW India. Monsoon advanced in to entire Uttrakhand, Himachal Pradesh and

entire Jammu and Kashmir, some parts of Uttar Pradesh, some parts of Haryana

including Chandigarh and Punjab on 1st July 2014. Advance of monsoon 2014 is

shown in the fig below.

2. Performance of Monson 2014:-

This year monsoon advanced in Haryana on 1st July in some parts and on

3rd

July in remaining parts and facilitated transplanting /sowing of paddy. Timely

and advanced forecast issued by Meteorological Centre, Chandigarh on 30th May

and subsequent update about poor and erratic monsoon rainfall in Haryana helped

the state administration to optimise various resources such as Irrigation, Power,

Agriculture, Health which in turn helped the state administration in planning.

Prevalent feature of monsoon 2014 in Haryana was erratic spread of rainfall on

temporal and spatial scale during entire monsoon season embedded with few

heavy/ extreme rainfall events in first fortnight of August and 1st week of

September but overall rainfall remained below normal in Haryana during

monsoon 2014. Spatial and temporal distribution of rainfall was poorly defined in

Haryana in the month of June, July and August however stress was significant

due very poor rainfall in the month of July & August.

3. Rainfall distribution (June – September) 2014

During monsoon 2014 state received 200.1 mm of rainfall against it normal

rainfall of 460.3 mm (1941 – 1990) which was 43% of LPA making it deficient

monsoon year as predicted by IMD in June 2014. In the last ten year (2005 –

2014), the rainfall during monsoon 2014 (June – September) was least in Haryana

and out of 21 districts for which data is available 11 districts i.e. 52% district

received scanty rainfall and 10 district i.e. 48% district received deficient rainfall.

During current monsoon season 24 western disturbance viz. upper air system,

Trough in westerly’s, Induced cyclonic circulation travelled eastward and were

also in interaction phase with monsoonal flow. One Low pressure area travelled

west/northwest ward along monsoon trough affected this region, 16 upper air

cyclonic circulations embedded in the region of monsoon trough were also

observed. Month wise location and dissipation of weather system during

monsoon 2014 is given below.

7. Withdrawal of Monsoon

In view of dry weather conditions and decreased moisture contents as seen

from water vapour imageries over Northwest region during 17th September

2014 and also change in the lower level tropospheric circulation pattern over the

region from cyclonic to anticyclonic during 16-17 made condition favourable for

withdrawal of monsoon over the region. Subsequently withdrawal of monsoon

over North-western parts of the country commenced on 23rd

September. Monsoon

withdrew from some parts of West Rajasthan and parts of Kutch on 23rd

September and from some parts of Punjab, Haryana and Gujarat region, some

more parts of Kutch and remaining parts of West Rajasthan on 26th

. During This

year monsoon withdrew from Punjab on 26th

September 2014. It further withdrew

from remaining parts of Punjab, Haryana including Chandigarh on
