Winter brings the shortest days and the least daylight ... in either hemisphere.
No. Sirius is a star that is seen during the winter months in the northern hemisphere.
During the spring, the length of the day (in the northern hemisphere) is increasing because the Earth is moving in its orbit around the sun, closer to the point at which the northern hemisphere is pointed toward the sun by 23 and a half degrees (the axial tilt) which gives it more daylight and less night.
The tilt of the earth's axis makes the amount of sunlight at different latitudes vary during the year
True
Assuming the observer is in the North, then the southern hemisphere would be tilted towards the sun during the Winter Solstice in December. However, for observers in the Southern Hemisphere, the Winter Solstice would occur in June, and the northern hemisphere would be tilted towards the sun.
The northern hemisphere will have daylight due to the tilt of the Earth's axis. As the Earth revolves around the Sun, different parts of the hemisphere receive varying amounts of sunlight throughout the year. This results in longer daylight hours during summer and shorter daylight hours during winter in the northern hemisphere.
They are actually observing it right now, during winter in the Northern hemisphere.
March 20th or 21st
the equator.
During the winter solstice in the northern hemisphere the 23 parallel in the southern hemisphere is receiving the most direct sunlight.
During the summer, the sun is striking the Northern Hemisphere straight on, therefore providing strong sunlight and longer daylight hours. The opposite is true during the winter; the Northern Hemisphere is turned away from the sun during this time, hence receiving weak sunlight and shorter daylight hours.
The whole area that's north of the arctic/polar circle has 24 h of daylight during summer. Part of that is Alaska, northern Scandinavia, Siberia etc.
Daylight hours on the winter solstice are shorter than the rest of the year because of the Earths rotational tilt. That tilt faces the northern hemisphere away from the sun. This causes the apparent position of the sun throughout the day to be the furthest south during the year and daylight hours to shorten. At the same time of the year the southern hemisphere is experiencing the exact opposite, the longest daylight hours of the year.
In December it is winter in the northern hemisphere
When Winter turns to Summer in the Northern Hemisphere, temperatures seem to increase on average. This is because Earth evolves around the Sun at an angle; and during the summer part of the revolution, the northern hemisphere tilts towards the sun, causing it to get hotter and temperatures to increase.
UK is in the northern hemisphere while south Africa is in the southern hemisphere. during december the suns rays fall directly on the southern hemisphere while northern hemisphere gets slant rays hence UK is colder in december than Africa.
Winter solstice will come for the northern hemisphere on December 21 in 2014. The region of earth that will have 24 hours of daylight is everything south of the Antarctic Circle.
