Circles of latitude between the 15th parallel north and the 20th parallel north

{{short description|Circles of latitude}} Following are '''circles of latitude between the 15th parallel north and the 20th parallel north''':

==16th parallel north== {{Location map-line|lat=16}} {{kml}} The '''16th parallel north''' is a circle of latitude that is 16 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Indian Ocean, the Pacific Ocean, Central America, the Caribbean, and the Atlantic Ocean.

At this latitude the sun is visible for 13 hours, 5 minutes during the summer solstice and 11 hours, 11 minutes during the winter solstice.<ref>{{Cite web|date=2019-09-24|title=Duration of Daylight/Darkness Table for One Year|url=http://aa.usno.navy.mil/data/docs/Dur_OneYear.php|url-status=dead|archive-url=https://web.archive.org/web/20191012094319/http://aa.usno.navy.mil/data/docs/Dur_OneYear.php|archive-date=2019-10-12|access-date=2021-03-10|website=U.S. Naval Observatory}}</ref>

===As a dividing line=== After World War II, the parallel divided Vietnam into Chinese military administration in the north and the British in the south (See Timeline of World War II (1945) and War in Vietnam (1945-1946)).

In the Chadian–Libyan conflict, from 1984 the parallel, known as the "Red Line", delineated areas controlled by opposing combatants. Previously the Red Line had been the 15th parallel north. (See also Operation Manta.)

===Around the world=== Starting at the Prime Meridian and heading eastwards, the parallel 16° north passes through:

==17th parallel north== {{For|the 1968 French documentary film|17th Parallel: Vietnam in War}} {{Location map-line|lat=17}} {{geoGroup}} The '''17th parallel north''' is a circle of latitude that is 17 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Indian Ocean, the Pacific Ocean, Central America, the Caribbean, and the Atlantic Ocean. The parallel is particularly significant in the history of Vietnam.

At this latitude the sun is visible for 13 hours, 9 minutes during the summer solstice and 11 hours, 7 minutes during the winter solstice.<ref>{{Cite web|date=2019-09-24|title=Duration of Daylight/Darkness Table for One Year|url=http://aa.usno.navy.mil/data/docs/Dur_OneYear.php|url-status=dead|archive-url=https://web.archive.org/web/20191012094319/http://aa.usno.navy.mil/data/docs/Dur_OneYear.php|archive-date=2019-10-12|access-date=2021-03-10|website=U.S. Naval Observatory}}</ref>

=== Vietnam === {{main|Vietnamese Demilitarized Zone|Partition of Vietnam}}

The '''Seventeenth parallel''' ({{langx|vi|vĩ tuyến 17}}) was the provisional military demarcation line between North and South Vietnam established by the Geneva Accords of 1954. The demarcation line did not exactly coincide with the 17th parallel but ran south of it, approximately along the Bến Hải River in Quảng Trị Province to the village of Bo Ho Su and from there due west to the Laos–Vietnam border.

In 1976 the demarcation line was made irrelevant as Vietnam was unified following the withdrawal of American forces and the surrender of the South Vietnamese government.

==20th parallel north== {{Location map-line|lat=20}} {{kml}} [[File:20th parallel Africa.svg|thumb|In Africa, the parallel defines part of the border between Libya and Sudan.]] The '''20th parallel north''' is a circle of latitude that is 20 degrees north of the Earth's equatorial plane. It crosses Africa, Asia, the Indian Ocean, the Pacific Ocean, North America, the Caribbean, and the Atlantic Ocean.

The parallel defines part of the border between Libya and Sudan.<ref name="Brownlie, I. ">{{Cite book|title=African Boundaries: A Legal and Diplomatic Encyclopedia|last=Brownlie|first=Ian|author-link=Ian Brownlie|publisher=Institute for International Affairs, Hurst and Co.|year=1979|pages= 133–40}}</ref> Within Sudan it defines the border between the Northern and North Darfur states.

At this latitude the sun is visible for 13 hours, 21 minutes during the summer solstice and 10 hours, 55 minutes during the winter solstice.<ref>{{Cite web|date=2019-09-24|title=Duration of Daylight/Darkness Table for One Year|url=http://aa.usno.navy.mil/data/docs/Dur_OneYear.php|url-status=dead|archive-url=https://web.archive.org/web/20191012094319/http://aa.usno.navy.mil/data/docs/Dur_OneYear.php|archive-date=2019-10-12|access-date=2021-03-10|website=U.S. Naval Observatory}}</ref>

On 21 June, the maximum altitude of the sun is 93.44 degrees and 46.56 degrees on 21 December. In this case an angle larger than 90° means that the culmination takes place at a maximum altitude of 86.56 degrees in the opposite cardinal direction. In the northern torrid zone, the Sun remains in the south during winter, but can reach over the zenith to the north in midsummer.

===Around the world=== Starting at the Prime Meridian and heading eastwards, the parallel 20° north passes through:
