The31st parallel north is acircle of latitude that is 31degreesnorth of theEarth'sequatorial plane. It crossesAfrica,Asia, thePacific Ocean,North America, and theAtlantic Ocean. At this latitude thesun is visible for 14 hours, 10 minutes during thesummer solstice and 10 hours, 8 minutes during thewinter solstice.[1]
Part of the border betweenIran andIraq is defined by the parallel.
In theUnited States, it defines part of the border between the states ofMississippi andLouisiana, and most of the border betweenAlabama andFlorida.Andrew Ellicott surveyed this parallel in 1797, which inPinckney's Treaty two years before had been defined as the border between the United States and the Spanish territory ofWest Florida.
Starting at thePrime Meridian and heading eastwards, the parallel 31° north passes through:
The32nd parallel north is acircle of latitude that is 32degreesnorth of theEarth'sequatorial plane. It crossesAfrica,Asia, thePacific Ocean,North America, and theAtlantic Ocean.
In theUnited States, the parallel defines part of the border betweenNew Mexico andTexas. It was the proposed route of theTexas Pacific Railroad.[2]
From 27 August 1992 to 4 September 1996, the parallel defined the limit of the southernno-fly zone in Iraq as part ofOperation Southern Watch. This limit was then moved to the33rd parallel north.[3]
At this latitude thesun is visible for 14 hours, 15 minutes during thesummer solstice and 10 hours, 3 minutes during thewinter solstice.[4]
Starting at thePrime Meridian and heading eastwards, the parallel 32° north passes through:
The33rd parallel north is acircle of latitude that is 33degreesnorth of theEarth'sequatorial plane. It is approximate at the midpoint between the equator (0 degrees) and theArctic Circle (66.6 degrees North Latitude.) It crossesNorth Africa,Asia, thePacific Ocean,North America and theAtlantic Ocean.
InIraq, the parallel defined the limit of the southernno-fly zone from 4 September 1996 to 30 August 2003. (Before this time, it had been set at the32nd parallel north) as part ofOperation Southern Watch.[5]
In theUnited States, it approximately forms the border betweenArkansas in the north andLouisiana on the south. (The border is actually a couple of kilometres north of the parallel.) TheLouisiana Territory was that part of the 1803Louisiana Purchase which lay north of the 33rd parallel.
The parallel is part of thehorse latitudes.
At this latitude thesun is visible for 14 hours, 20 minutes during thesummer solstice and 9 hours, 58 minutes during thewinter solstice.[6]
Starting at theprime meridian and heading eastwards, the parallel 33° north passes through:
The34th parallel north is acircle of latitude that is 34degreesnorth of theEarth'sequatorial plane. It crossesAfrica, theMediterranean Sea,Asia, thePacific Ocean,North America and theAtlantic Ocean.
The parallel formed the southern boundary of the originalColony of Virginia as outlined in theLondon Company charter.[7]
In theConfederate States, the parallel formed the northern boundary ofArizona Territory.[8]
At this latitude thesun is visible for 14 hours, 25 minutes during thesummer solstice and 9 hours, 53 minutes during thewinter solstice.[9]
Starting at thePrime Meridian and heading eastwards, the parallel 34° north passes through:
The35th parallel north is acircle of latitude that is 35degreesnorth of theEarth'sequatorial plane. It crossesAfrica, theMediterranean Sea,Asia, thePacific Ocean,North America and theAtlantic Ocean.
In theUnited States, the parallel defines the southern border ofTennessee, and the border betweenNorth Carolina andGeorgia, as well as thetripoint ofArizona–California–Nevada.
At this northern latitude, theSun is visible for 14 hours, 31 minutes on itssummer solstice (inJune) and for 9 hours, 48 minutes on itswinter solstice (inDecember).[10]
This parallel is sometimes used to define the northern boundary of thesubtropics.
Starting at thePrime Meridian and heading eastwards, the parallel 35° north passes through:
