[9] [failed verification] Each degree was subdivided into 60 minutes and each minute into 60 seconds. [10] [11] Thus, one Babylonian degree was equal to four minutes in modern terminology, one Babylonian minute to four modern seconds, and one Babylonian second to 1 / 15 (approximately 0.067) of a modern second.
A shortcut method for degrees Celsius is to count the number of chirps in 8 seconds (N 8) and add 5 (this is fairly accurate between 5 and 30 °C): T C = 5 + N 8 {\displaystyle \,T_{C}=5+N_{8}} The above formulae are expressed in terms of integers to make them easier to remember—they are not intended to be exact.
Christopher C. Burt, a weather historian writing for Weather Underground, believes that the 1913 Death Valley reading is "a myth", and is at least 2.2 or 2.8 °C (4 or 5 °F) too high. [13] Burt proposes that the highest reliably recorded temperature on Earth could still be at Death Valley, but is instead 54.0 °C (129.2 °F) recorded on 30 ...
The hourly PoP is the probability that more than 0.01 inches (0.25 mm) of precipitation would occur if conditions like those in the given hour continued for twelve hours. It can be similar to the daily PoP and vary little, or it can vary dramatically. the daily PoP will be the average of the hourly PoP across the whole day.
Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars . Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.
It may be in plural form as appropriate (for example, "it is 283 kelvins outside", as for "it is 50 degrees Fahrenheit" and "10 degrees Celsius"). [ 54 ] [ 5 ] [ 55 ] [ 56 ] The unit's symbol K is a capital letter, [ 39 ] per the SI convention to capitalize symbols of units derived from the name of a person. [ 57 ]
Aspect of slope (AS) is the compass direction towards which a slope faces, normal to the contours of elevation, given either degrees from true North N = 0° = 360° or as N, NE, E, SE, S, SW, W, NW. Time (t) is usually given in seconds for a measurement duration or in longer units to describe the age of snow deposits and layers.
An apparent solar day can be 20 seconds shorter or 30 seconds longer than a mean solar day. [ 9 ] [ 14 ] Long or short days occur in succession, so the difference builds up until mean time is ahead of apparent time by about 14 minutes near February 6, and behind apparent time by about 16 minutes near November 3.
