This extensive heat wave, with slight relief over the weekend, will continue to bring extreme temperatures to much of Argentina, from this Monday until Thursday or Friday.
In the Metropolitan Area of Buenos Aires, on those days the mass of warm and humid air will give way to a cold front and
the presence of the El Niño phenomenon will no longer be inhibited this February
.
In addition to these close swings in the thermal sensation (we are going to go from 39°C to more normal marks for the month, below 30°C), the thermometer that is too warm now is
the prelude to how this season will end
, even, of how autumn will begin, for a good part of Argentines (except Buenos Aires and Buenos Aires).
The National Meteorological Service (SMN) published its forecasts for the next quarter, which covers February-March-April, and the update is in favor of a milder climate for the City and the GBA, but less benevolent in the rest of the country. , who
will continue to be overwhelmed
.
"The most notable thing is that
the end of summer and beginning of autumn
are expected to have normal to above normal temperatures in much of the country, except in Buenos Aires and La Pampa, which will have normal temperatures,"

As compared to José Luis Stella, also from the SMN, in temperature "the area with the most chances in the normal category was reduced
."
Now only the central area of the country - the City, the Province, the entire Pampas region - is marked as the area that will remain within
the classic thresholds for the time
.
Contrary to this thermal pattern, the chances of above-normal temperatures
extend from one end of the country to the other
.
The big difference compared to the last weather report (January-February-March) is that
"extremely high" maximum temperatures
are now expected in the northwest, north, Cuyo and south of Patagonia.
At the beginning of the quarter, however, it is not ruled out that "a greater frequency of extremely high maximum temperatures may be observed in the center-west of the country."
If it happens, it would "eventually favor the occurrence of heat waves" in this part
until April
.
Temperatures will be in a range between normal or above normal in the Litoral region, Santa Fe, Córdoba and central and northern Patagonia.
Regarding rainfall
, the SMN expects that in the next three months rainfall will be above normal on the southern coast, and between normal or above normal in the northern coast, Santa Fe and Córdoba.
Meanwhile, they will be normal in the northern region and over eastern Patagonia, and lower than normal in the northwest region, and over western and southern Patagonia.
"For the central part of the country, the consensus was the
climatology
(from the forecasts): it was determined that there is no
more probable
category , as to say that it will be a hotter, drier or wetter quarter.
They all have the same chance of occurrence
", Stella brand
Likewise, the report points out that "the occurrence of
locally more intense precipitation events
than normal is not ruled out, especially towards the center-east and northeast of the country."
The climate on the coast
On the other hand, on the Atlantic Coast the parameters planned for the time were maintained.
"The area was also classified as
climatological
, that is, within the normal range in temperature and rainfall," clarifies the SMN spokesperson.
These average temperatures range between 23° and 26°C.
In reference to
the influence of El Niño and precipitation
, historical statistics from the meteorological organization indicate that six of the ten rainiest summers in the country and one of the ten warmest occurred under this phenomenon, since 1961 - when SMN measurements began - to the present.
El Niño is a
natural phenomenon
that develops due to the warming of the equatorial Pacific Ocean, which changes the circulation of the atmosphere, where rainfall and temperature patterns around the world are modified.
"The El Niño signal (which is inhibited during this heat wave)
will occur and will culminate in the fall
. But it is still stronger in the Litoral, Santa Fe and Córdoba, where the category above normal was set "In the center, the precipitation is losing signal (presence)," Stella closes.
