    Assam and Meghalaya recorded the highest rainfall in June in 121 years: IMD

    The average maximum, minimum, and mean temperatures for the entire nation during June 2022 were 34.12 degrees Celsius, 25.06 degrees Celsius, and 29.59 degrees Celsius, respectively, in contrast to the typical values of 33.73 degrees Celsius, 24.76 degrees Celsius, and 29.25 degrees Celsius based on the period of 1981–2010.

    Digital
    Desk: According to a climate summary for June prepared by the India
    Meteorological Department (IMD), Pune, rainfall over Assam and Meghalaya was
    the highest in June in 121 years with 858.1 mm, breaking the previous record of
    789.5 mm recorded in 1966. However, rainfall over Kerala and Mahe was the
    fourth lowest since 1901, with only 308.7 mm.



    color:black;mso-themecolor:text1">The survey also indicated that strong
    rainfall and lightning in the first month of the monsoon caused over 313
    fatalities, 72 injuries, 50 unaccounted-for deaths, and over 72,000 cattle
    losses.



    color:black;mso-themecolor:text1">Out of these, landslides, torrential rain,
    and flooding caused 191 people to pass away; 8 people to be hurt; 50 people to
    go missing; and 72,672 animals to perish.



    The
    northeastern states of Assam, Arunachal Pradesh, Meghalaya, and Manipur (Noney
    landslide) saw the greatest number of flood-related fatalities, whereas Bihar,
    Andhra Pradesh, Maharashtra, Uttar Pradesh, and Madhya Pradesh saw the greatest
    number of lightning-related fatalities.



    color:black;mso-themecolor:text1">The average maximum, minimum, and mean
    temperatures for the entire nation during June 2022 were 34.12 degrees Celsius,
    25.06 degrees Celsius, and 29.59 degrees Celsius, respectively, in contrast to
    the typical values of 33.73 degrees Celsius, 24.76 degrees Celsius, and 29.25
    degrees Celsius based on the period of 1981–2010.



    As a
    result, the country's mean temperature, average maximum temperature, and
    average minimum temperature were all 0.40 degrees Celsius, 0.29 degrees
    Celsius, and 0.35 degrees Celsius higher than average. Although early June had
    significant heat stress in some areas of northwest India, the average
    temperature may not have reflected the extremes because of pre-monsoon showers.
    In the last 121 years, the northwest of India experienced the 33rd-highest
    maximum temperature and the 25th-lowest minimum temperature.



    According
    to the climate summary, June's rainfall was distributed very unevenly.



    color:black;mso-themecolor:text1">Only two low pressure system days were
    recorded in June, compared to the average of 10.24, since only one low pressure
    system occurred over the Arabian Sea on June 27 and 28. In many areas of the
    country, the monsoon season's low-pressure systems are a major cause of
    significant and extremely high rainfall.



    The
    analysis stated that the lack of rainfall over the central Indian region in
    June was primarily due to fewer low-pressure systems.



    In
    2021, seven low-pressure systems that produced heavy rainfall in June formed.
    However, a number of weather stations, including Mawsynram, Forbesganj,
    Srinagar Aero, Batote, Mahabalipuram, Mysore, Silchar, and Najibabad, set new
    records for June rainfall this year.



    color:black;mso-themecolor:text1">The country as a whole recorded 152.3
    millimetres of rainfall in June 2022, which is 8% less than its Long Period
    Average (LPA) of 165.3 mm.



    color:black;mso-themecolor:text1">Central India experienced a 30% shortfall in
    rain, compared to a 12% deficit in the northwest, a 14% deficit in the southern
    peninsula, and a 22% surplus in the east and northeast.



    color:black;mso-themecolor:text1">One of the main causes of the uneven
    distribution of rainfall in June was the lack of low-pressure systems, which
    are crucial for bringing rain to central India. Patchy rains in India were
    caused, in part, by the Madden Julian Oscillation (MJO) being in an
    unfavourable location for rainfall and low typhoon activity across the
    northwest Pacific, according to OP Sreejith, head of the climate monitoring and
    forecast group at IMD, Pune.



    The
    majority of weather fluctuations in the area, including the south-west and
    north-east monsoons, are caused by the MJO, a band of rain clouds that sweeps
    eastward over the tropics.



    color:black;mso-themecolor:text1">It's interesting to note that the data did
    not represent the extremely high temperatures that northwest India saw in June.



    color:black;mso-themecolor:text1">"That is because there weren't many days
    with a heat wave and the rest of the time the temperature was normal."
    Sreejith continued. Temperatures were generally near normal or slightly above
    normal across the nation. 



    According
    to the Earth System Science Organization's (ESSO) and IMD's Seasonal Climate
    Outlook for South Asia, the equatorial Pacific is currently experiencing La Nia
    conditions. The monsoon season is likely to be marked by La Nia conditions. In
    some areas of the far northwest, north, and southeast Asia, the probability
    forecast for precipitation in June, July, and August indicates a higher
    likelihood of below-average rainfall, while the remainder of South Asia is more
    likely to see above-average precipitation.



    color:black;mso-themecolor:text1">Except for a few spots in the northwest, west,
    and northeast peninsular regions of South Asia where there is a moderate
    probability of above-normal temperatures, the probability forecast for
    temperatures for the season indicates a higher probability of below-normal
    temperatures over most of South Asia. Most of central and some areas of
    southeast Peninsular India, together with the majority of north India's
    Himalayan plains, are forecast to see below-average temperatures.



    color:black;mso-themecolor:text1">On Tuesday and Wednesday, broad and intense
    rains persisted throughout the west coast and central India.



    Extremely
    heavy rainfall (over 20 cm) occurred over a number of locations in Coastal
    Karnataka, West Madhya Pradesh, Konkan & Goa, and Madhya Maharashtra. Heavy
    to very heavy rainfall (11.5 to 20 cm) also occurred over Telangana, Odisha,
    Gujarat State, Assam, Meghalaya, Kerala, Mahe, Tamil Nadu, Puducherry,
    Karaikal, and South Interior Karnataka, and heavy rainfall at isolated
    locations.



    The
    low-pressure area that developed over Odisha on July 3 is now over Kutch and
    the surrounding area, and the cyclonic circulation it is associated with has
    reached mid-tropospheric levels. Over the next 24 hours, it is most likely to
    continue moving westward and lose some of its prominence. The monsoon trough is
    vigorous and farther south than usual. It is highly possible that starting
    tomorrow, its western end will progressively shift northward.



    color:black;mso-themecolor:text1">At mean sea level, there is an east-west
    shear zone. At mean sea level, a trough extends from the Gujarati coast to the
    Karnataka coast. Additionally, there is a cyclonic circulation over northern
    Odisha and neighbouring Chhattisgarh.
