Does Antarctica have high or low pressure?
The heat that is transported into Antarctica is largely from low pressure systems that form out to sea between 60 and 65°S in an area known as the circumpolar trough.
What temper is Antarctica?
How cold is Antarctica in winter? In winter, sea ice envelops the continent and Antarctica is plunged into months of darkness. The monthly mean temperature at the South Pole in winter hovers around -60°C (-76°F). Along the coast, winter temperatures range between −15 and −20 °C (-5 and −4 °F).
What is the highest recorded barometric pressure?
1083.8mb
The highest barometric pressure ever recorded was 1083.8mb (32 in) at Agata, Siberia, Russia (alt. 262m or 862ft) on 31 December 1968. This pressure corresponds to being at an altitude of nearly 600 m (2,000 ft) below sea level!
Can you breathe the air in Antarctica?
The air is so cold that it’s dangerous to breathe it directly. Instead, those who do brave the elements here often breathe through snorkels that pass through their jackets, allowing the body to warm the air.
Why is it so windy in Antarctica?
Wind. The strong winds of Antarctica are called katabatics, formed by cold, dense air flowing out from the polar plateau of the interior down the steep vertical drops along the coast. It is at the steep edge of Antarctica that the strong katabatic winds form as cold air rushes over the land mass.
What is the air pressure at the North Pole?
29.43
North Pole, AK Weather The barometric pressure is 29.43 – measured by inch of mercury units – and is since its last observation.
What is the coldest temperature ever recorded in Antarctica?
Interesting facts About Antarctica The coldest temperature recorded in Antarctica was -89.6°C at Vostok station in 1983.
What is the lowest pressure a human can survive?
Disregarding hypoxia, the lowest atmospheric pressure the human body can withstand is around 6 percent sea level pressure, or 61.8 millibars, below that pressure the water and blood in your body starts to boil.
What is the windiest country on Earth?
Part of the Antarctica: The Farthest Place Close to Home Curriculum Collection. It’s not just Antarctica’s temperatures that are so extreme. Winds speeds on the continent often exceed 100 mph each winter.
Is pressure greater at poles or equator?
The cold air at the poles is denser than the warm air at the equator; hence, air pressure at sea level is higher at the poles than at the equator.
Is air pressure greater at the equator or North Pole?
At the equator, the altitude is lower and also because of the direct heating of sun rays on the surface, the temperature is much higher than at the poles. This makes the air near the surface hot and lighter and hence it rises up which results in lower air pressure.
What is the coldest Earth has ever gotten?
minus 128 degrees Fahrenheit
The lowest air temperature ever measured by a weather station, minus 89 degrees Celsius (minus 128 degrees Fahrenheit), was recorded there at Russia’s Vostok Station in July 1983.
What pressure does blood boil?
A pressure of 6.3 kPa—the Armstrong limit—is about 1/16 of the standard sea-level atmospheric pressure of 101.3 kilopascals (760 mmHg)….Effect on body fluids.
| Location | Pressure |
|---|---|
| Mount Everest summit | 33.7 kPa (4.89 psi) (0.3326 atm) |
| Earth sea level | 101.3 kPa (14.69 psi) (1 atm) |
At what altitude will blood boil?
At the altitude of 18,590 metres (about 61,000 feet; or at 47 mm of pressure) the temperature required to boil water is only 98 °F (36.7 °C). A person’s normal body temperature is also about 98 °F, which means that liquids and tissues containing water in the body begin to vaporize at this pressure.
What depth of water will crush a human?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
