Thus, ten thousand years from now Earth's northern winter will occur at aphelion and northern summer at perihelion. The severity of seasonal change — the average temperature difference between summer and winter in location — will also change over time because the Earth's axial tilt fluctuates between 22.1 and 24.5 degrees.
The difference in the length of the day between summer and winter, from here to the north, begin to be striking – slightly more than 8 hours at winter solstice, to more than 16 hours during the summer solstice. Likewise is the difference in direction of sunrise and sunset. At this latitude at midnight (around 1 a.m. with summer legal hour ...
The amount of Sun energy reaching a location on Earth ("insolation", shown in blue) varies through the seasons.As it takes time for the seas and lands to heat or cool, the surface temperatures will lag the primary cycle by roughly a month, although this will vary from location to location, and the lag is not necessarily symmetric between summer and winter.
There are two different definitions of winter: meteorological and astronomical. One started Dec. 1; the other won't be here until Dec. 21.
In the lower middle latitudes where southern California, Egypt and South Africa are located, the seasonal difference is smaller, but still results in approximately 4 hours difference in daylight between the winter and summer solstices. The difference becomes less pronounced the closer one gets to the equator.
Adopted standard time of UTC+2 in 1903. Observed annual changes to summer time in 1942–1943 (UTC+3 summer, UTC+2 standard). Observed annual changes to winter time in 1994–2017 (UTC+2 standard, UTC+1 winter) in all regions except Zambezi, which remained in UTC+2 all year. [10] Netherlands: Observed DST in 1916–1945 and since 1977. New ...
Tropical savanna climate (Dry summer: As, dry winter: Aw). Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A . Tropical climates are defined by a monthly average temperature of 18 °C (64 °F) or higher in the coolest month, featuring hot temperatures and high ...
61. "Summer is the time for squabbles. In winter, we must protect one another, keep each other warm, share our strengths.” — George R.R. Martin
