Commonwealth Bay is listed in both the Guinness Book of World Records and the Eighth Edition of the National Geographic Atlas as the windiest place on Earth, with winds regularly exceeding 240 kilometres (150 mi) per hour and an average annual wind speed of 80 kilometres (50 mi) per hour.
The fastest wind ever recorded was in the base Belgrano II at 351 km/h (218 mph). Antarctica has the world's lowest rainfall average (zero at the Geographic South Pole) and thus is the world's driest continent. Despite its low rainfall average, Antarctica has approximately 70% of the world's fresh water (as well as 90% of the world's ice).
Fastest ever recorded: 484±32 km/h (301±20 mph) (3-second gust); calculated by a DOW (Doppler On Wheels) radar unit in the 1999 Bridge Creek–Moore tornado between Oklahoma City and Moore, Oklahoma, USA, 3 May 1999. Recently, the wind speeds were re-examined and adjusted to a maximum official wind speed of 321 mph (516.6 km/h).
A severe blizzard has winds over 72 km/h (45 mph), near zero visibility, and temperatures of −12 °C (10 °F) or lower. [5] In Antarctica, blizzards are associated with winds spilling over the edge of the ice plateau at an average velocity of 160 km/h (99 mph). [5]
^α Although Luis produced the highest confirmed wave height for a tropical cyclone, it is possible that Hurricane Ivan produced a wave measuring 131 feet (40 m). [41]^β It is believed that reconnaissance aircraft overestimated wind speeds in tropical cyclones from the 1940s to the 1960s, and data from this time period is generally considered unreliable.
A storm's strength is defined by its sustained wind speeds, with a Category 1 hurricane carrying wind speeds of 74-95 mph (119-153 kph), while a dangerous Category 5 storm has wind speeds of 157 ...
Two temperature records were set on February 6, one in each hemisphere, one for warmth, the other for mind-numbing cold. On Feb. 6, 2020, five years ago, Antarctica set its all-time record high of ...
Its sustained winds of 345 km/h (215 mph) are also the highest on record globally. Storms with a minimum central pressure of 925 hPa (27.32 inHg) or less are listed. Storm information was less reliably documented and recorded before 1949, and most storms since are only estimated because landfalls (and related reconnaissance) are less common in ...
