Anemia is a medical condition in which the red blood cell count or hemoglobin is less than normal. For men, anemia is typically defined as hemoglobin level of less than 13.5 gram/100 ml and in women as hemoglobin of less than 12.0 gram/100 ml. Anemia is caused by either a decrease in production of red blood cells or hemoglobin, or an increase in loss (usually due to bleeding) or destruction of red blood cells.
At an elevation of 2,835 meters (9,300 feet), South Pole has an average monthly temperature in the austral summer of -28Â°C (-18Â°F); in the austral winter, the average monthly temperature is -60Â°C (-76Â°F).
Antarctic weather. Antarctica is the coldest, windiest and driest continent on Earth. The average annual temperature ranges from about â10Â°C on the Antarctic coast to â60Â°C at the highest parts of the interior. Near the coast the temperature can exceed +10Â°C at times in summer and fall to below â40Â°C in winter. Over the elevated inland, it can rise to about â30Â°C in summer but fall below â80Â°C in winter. The lowest temperature yet recorded on the Earth's surface was â89.2Â°C at Vostok station on 21 July 1983. Surrounding Antarctica there is normally a belt of low pressure, the circumpolar trough, containing multiple low centres.
