Martian weather report with REMS


Meteorological report with REMS from Gale crater - year 33 month 10 & nbsp;

The tenth month of the thirteenth Martian year is the first of the
three months of summer in the Martian southern hemisphere. The temperatures
during this month they have remained below zero, as in the case of
most of the year. The average temperature has been approximately -40
° C, with a maximum daily average that has touched -12 ° C, while
the minimum average remains around -70 ° C. It should be remembered, without
However, the temperatures oscillate more than 60 ° C each day. Gone
the spring, in which solar radiation reached its maximum in the Gale crater, and so did its temperatures, which reached +3 ° C
absolute maximum at noon in a couple of suns (the Martian day is
called sun), the hottest of the year. In the previous month
produced the annual maximum of atmospheric pressure, coinciding with the
moment of maximum thawing of CO ice 2 from south polar ice cap
Martian, which when incorporated into the atmosphere in the form of vapor produced the increase in pressure. The atmosphere is very sensitive to input or
subtraction of CO 2 & nbsp; it is its main constituent. In the month
current the pressure begins to descend smoothly as the
planet is approaching the autumn equinox, at which time the CO 2 of the
atmosphere begins to freeze over the south polar cap, making
lower the pressure As expected, the pressure this month is lower
to the same month of the previous year since the rover has been ascending by the
Aeolis Mons and as the altitude increases, the pressure decreases.
So that the part can be understood more easily, we will include examples of what happens in our own planet. For example, this
month we have seen a meteorological phenomenon on Mars virtually the same & nbsp;
which occurs in some places on Earth, comparable to the winds
Foehn of the Alps or Chinook winds in the Rocky Mountains and is the
first time they are included in a Martian meteorological part. During
the sunset produces a thermal inversion layer that provides
the ideal conditions for the generation of the so-called mountain waves, the
which are so strong that they are capable of sinking masses of air that
They are hotter than those of the crater made inside. The masses of
hot air should rise instead of going down, but these
winds sink into the crater,
producing large oscillations in soil temperature in a very short time. This & nbsp; phenomenon also produces
rapid complete ventilation of the crater, something unique along the
Martian year. & nbsp;
