Cold crisis in South America


Worst situation in many decades. Huge losses expected in agriculture as frosts will continue for a few days ahead.   Electricity still out in many towns.

Update:

1- Chile and Argentina still working to recover electricity and water in many towns.

2- As of 18 Jul 17 almost the entire territory of subtropical South America (e.g. Argentina, Chile, Uruguay, southern states of Brazil and some zones of Paraguay) are covered with frosts or snow. It’s now expected this will be the worst situation recorded in many decades.

3- Huge losses are expected in agriculture as frosts will continue for a few days ahead.

4- In Brazil higher places are reaching down to -10°C and the polar air will continue its way to the north. Even some southern parts of Amazonia will be subject to its effects in 2 or 3 days.

  1. Here in the northwest, our summer is on the oddity side. We had a long cold and heavy snow over the winter of 16/17 and then a long wet spring lasting into late May. A lot of fields were plowed in as seed rotted or just didn’t geminate. We needed the wet no doubt but…as summer has progressed, we are in a temperature yo-yo. a week of 100 degree with records busted then cold fronts. in average we are seeing high 80s to mid 90s. Over night temps have dropped to just above freezing a few times. The hay crop has been good however the cereal crops are lagging.. but we are just nearing harvest time…so that is a wait and see. We still have August and September to go through but it “feels” like we are in early fall. I didn’t put in a garden this year as the soil just didn’t warm up enough until 3 weeks ago. I am putting my efforts in getting the green house going early as my intuition says we are in for another real winter. Here is another indicator of what is to come…we have had minimal fly, grass hopper and yellow jacket problems… the yellow jackets however are very aggressive and are looking for over wintering locations already instead of making as many nests as they can.
    A lot of this “abnormal” weather could be attributed to Iceland’s eruptions 2 years ago or lack of solar activity…but the world is starting to see the end of the endless days of summer heat we all grew up with and I suspect when the southern hemisphere turns to spring and summer, they too will see crop reductions.

  2. How the hell can the link no longer contain the above words? Are they trying to cover up the severity of the cold?

  3. Update 19 JUL 17:

    1- Record cold for the capitals of most States in Brazil for the last 4 years (2013 was another very cold winter to Brazil). Curitiba (PR), 800m height, and Porto Alegre (RS), at sea level, reached bellow zero temperature in many zones of the towns (via @metsul).

    2- In the State of Santa Catarina (SC), 1500m heighest point, temperature reached -8.8°C. In Rio Grande do Sul (RS), 1200m heighest point, -7.8°C. In Parana (PR), temperature reached -5.5°C. More than 100 towns reached negative temperatures in southern cities and frost covered almost the whole territory, including coastal towns and even some central zones of Porto Alegre (RS) and Curitiba (PR), both capitals having about 1.3 million inhabitants and metropolitan surrounding zones of over 3 million, being huge heat generators.

    3- The cold blast evolves in the north and northeast directions of the country and southern parts of Amazonia are facing temperatures as low as 7°C, which is quite rare for the rainforest. The 3 most populated States of Sao Paulo, Rio de Janeiro and Minas Gerais are now being affected and their capitals have experienced coldest days in the year.

    4- Reports on agriculture are quite sensitive to Brazilian economy as the country is the 4th largest producer of the world and aims to achieve #1 position in a decade. Maybe information on the agricultural subjects might be supressed after a few days or hours of exposure due to farmers/ governmental pressure. Nevertheless here comes a site that often offers information relating weather/climate and agriculture:
    https://www.climatempo.com.br/agroclima/

    5- Discrepancies in the values of temperatures are commonly found in Brazil as there are many different groundstation nets retrieving and publishing weather information. Bear in mind that Brazil has the 5th bigger territorial area among the countries (it’s bigger than the U.S. except for Alaska, and as big as the western Europe).

    The Federal Government has its National Institute of Meteorology-INMET but each Federal State and main the towns have their own groundstations like Porto Alegre (RS):
    http://www2.portoalegre.rs.gov.br/ceic/default.php?p_secao=45

    Even private nets are becoming bigger and openly accessed nowadays like the Charlier stations https://estacoes.charlier.com.br/# .

    Another facility that might be checked out is the site of the Federal National Institute of Space Research (INPE) which has a specific division to weather prediction and to analyze climate and weather (CPTEC) with historical proprietary data.
    http://www.cptec.inpe.br/cidades/tempo/237
    http://clima1.cptec.inpe.br/monitoramentobrasil/pt

    There it can also be found news, warnings, reports on weather, as much as satellite current images:
    http://satelite.cptec.inpe.br/home/index.jsp

    If you need information on the meteorological radars of the Brazilian Air Force you can check:
    http://www.redemet.aer.mil.br/?i=produtos&p=radares-meteorologicos

    You can also find more information and lots of pictures of the towns covered with frosts or snow in the Facebook pages or Twitter of Metsul (@metsul) and Climaterra (@climaterra), two prestigious and reliable private agencies placed in the south of Brazil.

    Finally remember that Brazilian territory comprises 4 different timezones and the official time is the Brasilia time zone (displaced 3:00 western of GMT). Translation of Brazilian sites in Portuguese is quite easily nowadays using facilities like Google translator.

  4. In Spanish, the posted time says:

    18/07/2017 às 09:19
    por Redação
    Atualizado 19/07/2017 às 13:05

    When I use Google translate, the first line comes out as “Posted” only. Unfortunately, the cached version has the updated text and archive.org doesn’t have that link archived.
