Table 2 gives the list of stations which received very heavy ( 12.5 cm) or extremely heavy ( 24.5 cm) rainfall in 24 hours during the month.
Daily rainfall (mm) for 10 major cities of India including the four metropolitan cities is shown in Fig. 8.
Standardized Precipitation Index
The Standardized Precipitation Index (SPI) is an index used for and is based only on precipitation. This index is negative for drought, and positive for wet conditions. As the dry or wet conditions become more severe, the index becomes more negative or positive. Fig 9(a, b, and c) give the SPI values for the month of July 2014, June 2014- July 2014 (2 months cumulative) and Jan-July 2014 (7 months cumulative) respectively.
During July, extremely wet/severely wet conditions were observed only over a small part of Odisha, Chattisgarh, West Madhya Pradesh, Bihar, Uttarakhand Extremely dry/severely dry conditions were observed over most parts of the country. However, these were more widespread over parts of northeastern region, Jharkhand, Bihar, Uttar Pradesh, Haryana, Chandigarh & Delhi, Punjab, East Madhya Pradesh, Marathwada, Chattisgarh and Tamil Nadu.
Cumulative past two months SPI values indicate, extremely wet/severely wet conditions over small parts of Arunachal Pradesh, Sub-Himalayan West Bengal & Sikkim, Bihar, West Madhya Pradesh and Chattisgarh, while extremely dry/severely dry conditions were observed over most parts of northern and northeastern region, parts of Madhya Pradesh, Madhya Maharashtra, Marathwada, Vidarbha, Chattisgarh, Coastal Andhra Pradesh, Telangana, Tamil Nadu, Coastal Karnataka, North Interior Karnataka and Kerala.
Cumulative SPI values of the past seven months indicate, extremely wet/severely wet conditions over parts of Bihar, Jammu & Kashmir, West Madhya Pradesh, South Interior Karnataka, while extremely dry/severely dry conditions were observed over most parts of northern and northeastern region, parts of East Madhya Pradesh, Marathwada, Chattisgarh and Kerala.

Fig.19 shows the mean temperature for the country as a whole for July since 1971. Five year moving 0average values are also shown. The mean temperature for the month this year (28.47 C) was the third
0 0highest since 1971 after 1987 (28.56 C) and 2009 (28.5 C).
Fig. 20(a) & 20(b) show the maximum and minimum temperature series respectively for the country as a whole and the four homogeneous regions during the month since 1971. Maximum temperature was above
0 0normal over the country as a whole by 0.9 C. It was above normal over the East & Northeast India by about 0.5 C 0and over other three regions by about 1 C. Similarly, minimum temperature was above normal over the country
0 0as a whole by 0.7 C. Over Northwest India, it was above normal by about 0.4 C, over the East & Northeast and 0 0Central region by about 0.7 C and South Peninsula by about 1 C.
Low Pressure Systems
st rdThe only depression of the month formed over the North Bay of Bengal during 21 23 July and moved westwards.
The depression was first seen as a low pressure area over the North Bay of Bengal and adjoining areas th of Gangetic West Bengal and Odisha on 20 and rapidly concentrated into a depression over northeastern
parts of Odisha and adjoining areas of Gangetic West Bengal and lay centred near Lat. 22.0N / Long. 87.0E stabout 50 kms east of Baripada on the morning of 21 . It moved northwestwards and lay centred over south
Jharkhand and neighbourhood near Lat. 22.5N / Long. 85.0E about 100 kms westsouthwest of Jamshedpur in stthe evening of 21 . It moved westwards and lay centred over north Chattisgarh and neighbourhood near Lat.
nd22.5N / Long. 81.0E about 100 kms southeast of Pendra on the morning of 22 . It moved westwards and lay centred over east Madhya Pradesh and neighbourhood near Lat. 22.5N / Long. 81.0E about 100 kms
ndsoutheast of Jabalpur in the evening of 22 . It further moved westwards and lay centred over West Madhya Pradesh and neighbourhood near Lat. 22.5N / Long. 77.5E about 50 kms southeast of Bhopal on the morning
rd rdof 23 . It weakened into a well marked low pressure area over the same region by 1430 hrs IST of 23 and lay thover northwest Madhya Pradesh and neighbourhood as a low pressure area on the evening of 24 . It moved and
thlay as a low pressure over southwest Rajasthan and neighbourhood on the evening of 24 and later merged with the monsoon trough. Fig. 21 shows the track of this depression.
stApart from this depression, three low pressure areas formed over north / northwest Bay of Bengal on 1 , th th11 and 27 of the month. These low pressure areas crossed the coast and moved in a northwesterly direction
across the central parts of the country and persisted for 4 to 7 days.
The depression and these low pressure areas caused good rainfall over the concerned parts of the country.
SST anomaly over the Indian & Pacific Ocean
Fig.22 shows the anomaly in sea surface temperature over the tropical Indian and Pacific Oceans.Above normal anomaly in the sea surface temperature was observed over the eastcentral and northeastern equatorial Pacific Ocean. Southern part of Arabian sea, was warmer than the normal.
SOI and Pacific SST Index
SOI (Table 3) was negative (-0.2) during the month. SST decreased slightly over all the Nino regions. The SST anomaly indices over the NINO region indicate prevalence of moderate El-NINO event.
Fig.23 shows the CPC/IRI consensus ENSO forecast for the coming seasons. Strengthening of El-Nino condition is expected in the coming seasons as it has the highest probability.
