  2. Effect of Sun angle on climate - Wikipedia

    en.wikipedia.org/wiki/Effect_of_Sun_angle_on_climate

    For example, with an axial tilt is 23°, and at a latitude of 45°, then the summer's peak sun angle is 68° (giving sin(68°) = 93% insolation at the surface), while winter's least sun angle is 22° (giving sin(22°) = 37% insolation at the surface). Thus, the greater the axial tilt, the stronger the seasons' variations at a given latitude. [4]

  3. Axial tilt - Wikipedia

    en.wikipedia.org/wiki/Axial_tilt

    The rotational axis of Earth, for example, is the imaginary line that passes through both the North Pole and South Pole, whereas the Earth's orbital axis is the line perpendicular to the imaginary plane through which the Earth moves as it revolves around the Sun; the Earth's obliquity or axial tilt is the angle between these two lines.

    This SVG diagram contains embedded raster graphics. Such images are liable to produce inferior results when scaled to different sizes (as well as possibly being very inefficient in file size). If appropriate to do so, they should be replaced with images created using vector graphics .

  5. Milankovitch cycles - Wikipedia

    en.wikipedia.org/wiki/Milankovitch_cycles

    Axial precession will promote more extreme variation in irradiation of the northern hemisphere and less extreme variation in the south. When the Earth's axis is aligned such that aphelion and perihelion occur near the equinoxes, axial tilt will not be aligned with or against eccentricity. [citation needed]

  6. Earth phase - Wikipedia

    en.wikipedia.org/wiki/Earth_phase

    Earth's phase changes angle throughout the seasons due to Earth's axial tilt, here viewed from geostationary orbit. Among the most prominent features of the Moon's sky is Earth. Earth's angular diameter (1.9°) is four times the Moon's as seen from Earth, although because the Moon's orbit is eccentric, Earth's apparent size in the sky varies by ...

  7. Season - Wikipedia

    en.wikipedia.org/wiki/Season

    The seasons result from the Earth's axis of rotation being tilted with respect to its orbital plane by an angle of approximately 23.4 degrees. [9] (This tilt is also known as "obliquity of the ecliptic".) Regardless of the time of year, the northern and southern hemispheres always experience opposite seasons.

    Jun. 26—This week marks the end of June and we are heading rapidly around the sun. Because our planet has that interesting tilt to it, the northern hemisphere is collecting many hours of ...

  9. Axial parallelism - Wikipedia

    en.wikipedia.org/wiki/Axial_parallelism

    Axial parallelism of the Earth's tilted axis is a primary reason for the seasons. The Earth's orbit, with its axis tilted at 23.5 degrees, exhibits approximate axial parallelism, maintaining its direction towards Polaris (the "North Star") year-round. Together with the Earth's axial tilt, this is one of the primary reasons for the Earth's ...
