Freezing [1] or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K). This is usually measured at the height of 1.2 metres above the ground surface. This is usually measured at the height of 1.2 metres above the ground surface.
The record high temperature at the National Weather Service office in San Diego of 111 °F (44 °C) was on September 26, 1963. The record low temperature was 25 °F (−4 °C) on January 7, 1913. [8] The record high temperature was tied only once and happened on September 27, 2010, 47 years and two days after the set record.
The temperature announced reflects that of the ice surface, while the Vostok readings measured the air above the ice, and so the two are not directly comparable. More recent work [5] shows many locations in the high Antarctic where surface temperatures drop to approximately −98 °C (−144 °F; 175 K). Due to the very strong temperature ...
The coldest month was August 1987 with a mean temperature of −75.4 °C (−103.7 °F) and the warmest month was December 1989 with a mean temperature of −28 °C (−18 °F). [25] In addition to the extremely cold temperatures, other factors make Vostok one of the most difficult places on Earth for human habitation:
In Southern California, the temperature differences are approximately 4 °F in winter and 23 °F (2 °C and 13 °C) in summer. At the coast in Santa Monica, the average high in August is 75 °F (24 °C), while in Burbank, approximately 10 miles (16 km) inland, the average high in August is 95 °F (35 °C): a temperature gain of about two ...
Part of the 2020–21 North American winter. The February 2021 North American cold wave was an extreme weather event that brought record low temperatures to a significant portion of Canada, the United States and parts of northern Mexico during the first two-thirds of February 2021. The cold was caused by a southern migration of the polar vortex ...
Temperatures stayed below freezing for up to eight hours at some valley locations, resulting in significant damage to plants and commercial agriculture. [23] In the winter months, high-pressure systems over the deserts often bring Santa Ana winds, resulting in dry, and dusty days. On rare occasion, temperatures can reach into the 85 to 95 °F ...
The properties of ice II were first described and recorded by Gustav Heinrich Johann Apollon Tammann in 1900 during his experiments with ice under high pressure and low temperatures. Having produced ice III, Tammann then tried condensing the ice at a temperature between −70 and −80 °C (203 and 193 K; −94 and −112 °F) under 200 MPa ...
