Sun Compass Southern Hemisphere Everyone knows the sun rises in the east and sets in the west. Using the shadow and stick method you can also get an accurate north/south line and determine your principle compass points. Most survival manuals (and other Youtube videos) show this technique as it is used in the Northern Hemisphere. In the Southern Hemisphere the sun moves through the northern sky at noon. . The noontime shadows are pointing south rather than north and they move counterclockwise. This can mess up the internal sense of directon from people from the northern hemisphere as their intuitive sense of north and south gets flipped on its head. This same method can be used in the Northern Hemisphere, just remember that the base of your shortest noontime shadow is pointing south and the tip is pointing north.

Mechanism of The Seasons Mechanism of The Seasons The seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees. Thus, at any given time during summer or winter, one part of the planet is more directly exposed to the rays of the Sun. This exposure alternates as the Earth revolves in its orbit. . Therefore, at any given time, regardless of season, the northern and southern hemispheres experience opposite seasons. The effect of axis tilt is observable from the change in day length, and altitude of the Sun at noon (the culmination of the Sun), during a year. Seasonal weather differences between hemispheres are further caused by the elliptical orbit of Earth. Earth reaches perihelion (the point in its orbit closest to the Sun) in January, and it reaches aphelion (farthest point from the Sun) in July. Even though the effect this has on Earth's seasons is minor, it does noticeably soften the northern hemisphere's winters and summers. In the southern hemisphere, the opposite effect is observed. Seasons result from the yearly revolution of the Earth around the Sun and the tilt of the Earth's axis relative to the plane of revolution. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to go into hibernation or to migrate, and plants to be dormant. During May, June and July, the northern hemisphere is exposed to more direct ...
