  2. Season - Wikipedia

    en.wikipedia.org/wiki/Season

    The solar seasons change at the cross-quarter days, which are about 3–4 weeks earlier than the meteorological seasons and 6–7 weeks earlier than seasons starting at equinoxes and solstices. Thus, the day of greatest insolation is designated "midsummer" as noted in William Shakespeare 's play A Midsummer Night's Dream , which is set on the ...

  3. Effect of Sun angle on climate - Wikipedia

    en.wikipedia.org/wiki/Effect_of_Sun_angle_on_climate

    This is a diagram of the seasons. Regardless of the time of day (i.e. Earth 's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter . Figure 3 shows the angle of sunlight striking Earth in the Northern and Southern Hemispheres when Earth's northern axis is tilted away from the Sun ...

  4. Seasons on planets - Wikipedia

    en.wikipedia.org/wiki/Seasons_on_planets

    Given the different Sun incidence in different positions in the orbit, it is necessary to define a standard point of the orbit of the planet, to define the planet position in the orbit at each moment of the year w.r.t such point; this point is called with several names: vernal equinox, spring equinox, March equinox, all equivalent, and named considering northern hemisphere seasons.

  5. Solstice - Wikipedia

    en.wikipedia.org/wiki/Solstice

    The seasons occur because the Earth's axis of rotation is not perpendicular to its orbital plane (the plane of the ecliptic) but currently makes an angle of about 23.44° (called the obliquity of the ecliptic), and because the axis keeps its orientation with respect to an inertial frame of reference. As a consequence, for half the year the ...

  6. Sun path - Wikipedia

    en.wikipedia.org/wiki/Sun_path

    The pictures below show the following perspectives from Earth, marking the hourly positions of the Sun on both solstice days. When connected, the suns form two day arcs, the paths along which the Sun appears to follow on the celestial sphere in its diurnal motion. The longer arc is always the midsummer path while the shorter arc the midwinter path.

  7. Tropics - Wikipedia

    en.wikipedia.org/wiki/Tropics

    When the wet season occurs during the warm season, or summer, precipitation falls mainly during the late afternoon and early evening hours. The wet season is a time when air quality improves, freshwater quality improves and vegetation grows significantly due to the wet season supplementing flora, leading to crop yields late in the season.

  8. Axial precession - Wikipedia

    en.wikipedia.org/wiki/Axial_precession

    The equinoxes occur where the celestial equator intersects the ecliptic (red line), that is, where the Earth's axis is perpendicular to the line connecting the centers of the Sun and Earth.The term "equinox" here refers to a point on the celestial sphere so defined, rather than the moment in time when the Sun is overhead at the Equator (though ...

  9. Category:Seasons - Wikipedia

    en.wikipedia.org/wiki/Category:Seasons

    Articles relating to seasons, divisions of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth , seasons are the result of Earth's orbit around the Sun and Earth's axial tilt relative to the ecliptic plane.
