1 The change of the dark pattern
The second half of the last season, the next pattern seems to be changing.
It created this program from the report which was reported by the Kansai brach.
T. Ikemura created the material which becomes a basis and Adachi gathered.
(1) Syrtis Major
The whole seems lean. The latitude in the northern top isn't changing.
It is difficult for Syrtis Major to be able to see the west from the top.
There is possibility to be covered with sand in this part.
This part recieves a west wind by dust storm who advanced towards the east.
The band of sand to the direction of east and west may be able to be seen on
the Syrtis Major.
(2) Daedaria region
In 1973, after big dust storm occured, the big dark pattern emerged to Daedaria
region.
This time, too, the possibility of the pattern which is similar to the same
place to be made is big. This state is caught by dust storm's image after ending.
It thinks that to be doing the change which is the same twice undergoes influence
by the landform. This is the way of thinking which is the most obedient.
Daedaria received approaching by thick dust storm who came from the west.
This district is located in the west of the big upland which is in the south of
the Solis lacus. It thinks that sand was blown by dust storm's strong wind.
Therefore, a dark pattern was made. It wants to take a form with new pattern.
Sand wants to search for where it went. As for sand, will it have been transferred
to the west of the Solis lacus?
(3) Solis lacus
There is little information on this area. However, an important change is seen.
A little than the position so far Solis lacus shift to the south and can be seen.
Also, it is difficult that it is possible to see the western side, too.
The band which is not around so far is seen. This part needs note.
(4) Aurorae sinus
Daedaria, Solis lacus and Aurorae sinus may be a continued change.
These are the area which connects with the top of the belt. In 2002, dust storm
becomes a light band and is the area which can have been seen, stagnating.
The Aurorae sinus seems to be fattening mainly.
(5) Martian surface :low contrast ?
Dust storm spread to the surface in the Mars. How much did dust storm compose?
The contrast may be still low. It is possible to judge whether or not the contrast
is low when doing the processing which is the same as the time of 2001 about the
image and comparing it. When it will reproduce a dark pattern, don't make a
contrast strong.To catch the change of the dark pattern, it wants to take a
photograph in the R and IR band.
2 The dust storm's occurrence time
location Ls
1956 Noachis 240d
1971 Noachis 260d
1973 Solis Lacus 300d
1977 Solis Lacus 268d
2001 Mare Tyrrhenum 185d
In 2001, veil of the dust took immediately before dust storm occured and Hellas
got out of sight. Also, the contrast became low about the neighborhood of the
Hellas, too. As for dust storm's appearance, the discovery of such a sign
phenomenon is important. When veil begins, the temperature of the atmosphere
rises and it becomes easy for the dust storm to come out.
Generaly, it hangs and it the photograph takes a filter but wishing to put value
with wavelength in the image.
(1) The relation between the small dust storm and the wind direction
When the diameter exceeds 10 seconds, the occurrence of the small scale dust is taken.
The ups and downs of the dust are a big problem. this is not to be until it says, too.
The dust occurred, the wind which is blowing to the district must be examined.
It wants to examine weather or not the veil doesn't form in the downwind side of the
dust. When veil is made, the temperature of the atmosphere rises surely.
(2) water ice cloud of the low latitude region
It intends to gather water ice cloud in 2003.
In 2001, the water ice cloud which is thick with the front of letting out to be large
in scale is observed. It wants to pay attention to the influence which thick cloud gives
the atmosphere.
