– Unlike another countries, there’s no much culture of
checking out the weather forecast. However, it uses to be criticized,
especially if it doesn’t match with current conditions.
much people than we imagine are expectant about this information.
Peru, there is an official agency in charge of monitoring , SENAMHI,
and there are personalities at the market such as Abraham
or even AccuWeather
(used by FACTORTIERRA.NET) to know how dressing, when seeding, or if
it’s worthy to have a BBQ.
data come from meteorological stations installed nationwide,
including what National
University of Piura
(UNP as in Spanish) monitors in Miraflores, Castilla [pronounce
“Castija”] District, watching what happens in atmosphere
and soil 30 km around. It also receives reports across the region
everyday, holidays inclusive.
Meteorological Station has two arreas: Agrimeteorologics, that
measures soil temperature, and Climatology, that takes values from
air temperature and humidity, those are mostly used for weather
first area is composed by geothermometers buried in different depths.
“We’re involved on looking for values of soil behavior,”
specialist Milagros Córdova explains. In fact, instruments are
set 2 cm, 5 cm, 10 cm, 20 cm, 30 cm, 50 cm and 1 meter, so different
values are gotten.
there’s most solar warming, temperature values are going down,
but in some cases, at 2 pm., values raise,” specialist adds.
depth is not enough but soil coverage. That’s why the station
has three spaces: one whenn it’s uncovered, another one is
grass-covered, and the last one is trash-covered. Then,
data are also different.
the three values and applying formulas, one value is gotten,”

to avoid data alteration.
has an aspiretrichrometer,
that gives us temperature from dry thermometer and wet thermometer.
The two are equal but the wet one has a tiny cloth when getting
moisture then becoming colder, allows to know the current
relative humidity is calculated from oscillation of both instruments
and it’s checked out by a symethrical table.
also has a thermometer for high temperatures and another for low
temperatures. This is the information usually sent to SENAMHI and the
recently, the media are looking for more meteorological parameters,
like relative humidity for what the station has a hydrometer, that gives
data every 60 minutes. So, combining temperature plus humidity, it’s
possible to get thermic sensation, or how cold or heat are perceived by
parameters looked for the media are air direction and intensity, what
can be forecasted by using water, water temperature actually. The
station has an evaporation tank, which has a gholed hlass and a
mycrometric rule for knowing the water level, that is changed every

verify its function. Meanwhile, pluviometers say how much rain fell
and how much it lasted as well.

medium clodness is studied, especially cirrus clouds, those are snow
drops suspended 9000 meters above our heads, visible from the soil
like threads. Their
behavior reveals how the wind is moving on.
atmospheric pressure is verified by a barometer , that gives its data
in milibars, and a mycrobarometer, That give them on mercury columns
if you know how the wind flows on, how much humidity is, and if it’s
cold or hot, you’ll know where and when it will rain. “Any
information can be missed,” Córdova emphasizes.
