This system can suit to the climate environment of very high temperature high moisture and very low temperature - supersaturation; it has a self-protection ability to against the hurricane - force wind over force 12 and the strong vibration during icebreaking, as well as strong magnetic disturbance. It has two sets of receiving-imagery processing systems for polar orbit low-resolution and quasi-stationary high-solution satellites. The key creation Points of this system are as follows: 1. the active gyro-control stabilization platform and a mixed mounting system of three rotating a - B and x -- y axes are used. It solved the tracing difficulties both in the low elevation angle and very high elevation angle of polar-orbit satellite, even in the status of ship moving with continuously changing its poition, direction and ship roll and pitch. 2. Imagery processing subsystem. The newest BORLAND-- DELPHI language and PASCAL language pro gramming software are used under WINDOWS 95 environment. It has a dynamic positioning nested-grid system and electric mapping grid data system. It can show the latitude-longitude of any point on the map, and marks any object such as ship, station or island, and draws the route. It can monitor cloud and temperature, forest fire, anomalous change of ocean and land. It can output satellite cloud maps of 24 bit with very high clarity. This system is very advanced in technique for the whole structure with the features of small volume, light weight and very low cost. It suits to very bad climate and ocean environment. Its imagery process ing system has complete functions with high resolution and being very easy to operate. It is not only suit to land use, but also and specially to all kinds of ship over the sea. It can be extended to domestic and international use. This system played a very important role in the 14th Chinese Antarctic Exploration Navigation, and was introduced a broad attention paid by Chinese newspapers and TV Stations.展开更多

It is found that the sea ice area in the Antarctic in the 1980s was significantly less than in the 1970s and the average global sea level height value in the 1980s was also significantly higher than in the 1970s. Connecting variation of both and analyzing their physical mechanism, it indicates that the accumulated sea ice anomaly value in the 1980s less than in the 1970s means a global climate warming, the sea water temperature and air temperature were obviously higher in the 1980s it introduced the long-term accumulated sea ice decreased greatly; a higher sea water temperature introduced sea water volume expanding, and more icebergs transporting from the ice cover in the Antarctic continent to ocean in the warmer year. As a result induced by these multi-causes, the global sea level raised significantly in the 1980s. The global average sea level value in the 1980s, was 22 mm higher than in the 1970s. The sea level raising(SLR) was distributed unevenly. It is especially true in the Pacific Ocean with two expensive we level raising regions in the Northeast Pacific and Southeast Pacific as well as a raising region near the Bering Sea; and with two descent regions in the Northwest and Southwest Pacific. It is considered that this kind of uneven SLR distribution closely relates to the sustained decreasing of the Antarctic sea ice. The higher sea water tem This study was supported both by the National Natural Science Foundation of China under contrast Nod 49376252 and by the National '85' Plan 'Key Project 903': 7th Popect.perature in the south ocean introduces a rather warmer water temperature of the Peru Cold Current which is a northward branch of the South Oceanic Current along the South American continent, then it is easier to the occurrence of El Nino event. When El Nino event occurs, the prevailed tropical easterlies over the Pacific weaken and the westerlies intensify. Normally, the sea level is higher in the west and low in the east. A lot of sea water is transported from west to east caused by gravity and wind dynamics in this situation. The uneven distribution of raising in the eastern Pacific and descending in the western Pacific was introduced.展开更多

Region Ⅰ(0°～120°E) is a zonal area which includes the Prydz Bay area, and sea ice area extending from the Weddell Sea,Region Ⅱ (120°E～120°W) mainly includes the Ross Sea area, and Region Ⅲ (120°W～0°) mainly the WeddellSea area. Of all the regions, the ice area in Region Ⅲ is the largest, and that in Region Ⅰ is the smallest.In the Antarctic,the seasonal changes of the sea ice are very obvious, during summer, in February, there isleast sea ice in the Southern Ocean, the net sea ice area (not include the area of open water) is about 3 190 000 km2,during winter, in September, there is most sea ice in the Southern Ocean, the area index is about 16 840 000 km2,nearly 5. 3 times of that in February. The seasonal change of sea ice is one month lag of the changes of the air temperature, but almost synchronous with that of SST.Of all the three regions divided above, there are some points both common and uncommon in their sea icechange cycles, the common features are that there exist one and a half years, one year and ten-months secondaryperiods in all three regions, but their main periods are not the same, they are about 5, 11 and 6 a in Regions Ⅰ,Ⅱ,and Ⅲrespectively. The main periods of the sea ice change in Regions Ⅰand Ⅱ are very close because the ice areaextended eastward from the Weddell Sea ice area of Region Ⅲ is one of the main components of the Region Ⅰ. It isalso worth pointing out that in Region Ⅱ, southward extension of the Pacific Ocean, there exist not only a 11-yerasmain period but also a 2-yeras secondary period, which does not exist in the other two regions.展开更多
