During the winter, the region experiences 24 hours of darkness in a day and 24 hours of sunlight in a day during the summers. Another reference for the Tropic of Cancer is the Northern Tropic. The Northern Tropic is the parallel at which the Summer or Nothern or June Solstice occurs when once a year the sun appears directly overhead the most northerly parallel.
This event happens in the month of June. The Southern Tropic is another reference for the Tropic of Capricorn. The Tropic of Capricorn is the parallel at which the Winter or Southern or December Solstice occurs when once a year the sun appears directly overhead the most southerly parallel.
This event happens in the month of December. These two parallels enclose the area of the Earth known as The Tropics characterized by warm to hot weather and lush vegetation.
It is identified as the latitude that falls at the point that is equidistant from the North Pole and the South Pole. The Earth is tilted with respect to the ecliptic plane by Globes are typically built with an inclined rotation axis. In the Northern Hemisphere, the Sun will pass directly over head only between June 20 and 22th along the Tropic of Cancer. That day is called the day of the summer maximum or Solstice in the Northern Hemisphere.
In the Southern Hemisphere, the Sun will pass directly over head only once between December 20 and 23rd along the Tropic of Capricorn.

Anywhere between the Tropic of Cancer and the Tropic of Capricorn, the Sun will pass directly overhead at least twice during the year, but the Sun will never pass overhead for people living outside the tropics. Within the Tropics, over the course of a year, the Sun's position in the sky changes, beginning in the southern sky about December 21, moving to the northern sky in mid-year, and ending the year back in the southern sky. When the sun lies at one of the intersections, it is directly overhead somewhere on the equator.
This occurs at the equinox, and the points on the sky where the equinox intersects the equator are also called equinoxes. Once every year, the Sun passes through the equator going north. This happens in late March — the "vernal" or "spring" equinox. The "autumnal" equinox occurs when the Sun passes through the equator in late September.
On the equinox days, the day and night are equally long. This is the origin of the name equinox, which is from Latin for "equal night.
It doesn't rise to directly overhead, though, except for observers on the Equator. The equinoxes are the only days of the year that have twelve hours of daylight and twelve hours of dark. After the vernal equinox, moving into Northern summertime, the Sun begins rising in the northeast and sets in the northwest. Days in the Northern Hemisphere become longer, while days in the Southern Hemisphere become shorter.
The points at which the Sun is at its greatest distance from the equator are called the solstices.

The solstices mark the longest and shortest day of the year. The longest day of the year is the summer solstice and the shortest day is the winter solstice.
In the Northern Hemisphere, the summer solstice occurs when the Sun is farthest north, while the winter solstice occurs at the Sun's southernmost point. In the Southern Hemisphere, the solstices are reversed.
Viewed from space, we see that the Earth's tilt changes the exposure of different parts of the Earth to the Sun. Observers in the Northern Hemisphere will see the Sun at its lowest position in the southern sky, about December They see it this way because the Southern Hemisphere is tilted towards the Sun and the Northern Hemisphere is tilted away.
About June 22, the situation is reversed, with the Northern Hemisphere pointed toward the Sun, and the Sun will be in its extreme high point in the sky at solar noon.
For an observer in the Southern Hemisphere, the Sun will appear at its lowest point in the sky in the north, about June 22, while the Sun will appear at its high point in the sky about December One effect of this phenomenon is that during the months of Northern Hemisphere summer, the North Pole will be able to receive sunlight twenty-four hours a day.
The Sun will remain visible through much of the autumn, passing below the horizon at the autumnal equinox. As winter sets in at the North Pole, the Sun will not be seen for six months, while that portion of the Earth is tilted away from the Sun. As one moves toward the Earth's equator from either pole, this effect becomes less severe. The nearer one is to the equator, the less difference there will be between the number of hours of illumination and night hours.
At the equator, there's practically no difference between the length of day all through the year. Clearly, the annual motion of the Earth around the Sun is the cause of Earth's seasons. What effect gives rise to this seasonal change is less obvious.
This is the Hadley-Ferrel Model. Land heats up and cools down faster than water. This explains why temperatures are so extreme here in Nebraska landlocked, with no ocean to absorb heat. Ocean Currents--as it is with air in the atmosphere, water circulates across the planet; these movements are called currents. The Gulf Streaman ocean current consisting of largely warm water, contributes to the mild climate of Western Europe because it flows past the western part of this continent.
Circulations of ocean currents are much like the circulation of air. Warm ocean currents are warm water from the tropics releasing energy as it reaches other area. Cold ocean currents are cold water moving from higher latitudes to the equator.

They absorb energy received in the tropics thus cooling the air above. A distinct correlation between the pattern of ocean currents and the air circulation above them can me made.
The Koeppen Climate Classification System is the most widely used for classifying the world's climates. Most classification systems used today are based on the one introduced in Koeppen.
Koeppen divided the Earth's surface into climatic regions that generally coincided with world patterns of vegetation and soils.
