The36th parallel south is acircle of latitude that is 36degreessouth of theEarth'sequatorial plane. It crosses theAtlantic Ocean, theIndian Ocean,Australasia, thePacific Ocean andSouth America.
Starting at thePrime Meridian and heading eastwards, the parallel 36° south passes through:
The37th parallel south is acircle of latitude that is 37degreessouth of theEarth'sequatorial plane. It crosses the Atlantic Ocean, theIndian Ocean,Australasia, the Pacific Ocean and South America.
This parallel approximates that latitude at whichsolar irradiance equals the planetary average,[1] with higher insolation equatorward and lower poleward.
An exploration of the 37th parallel south is the theme ofJules Verne's novelIn Search of the Castaways. Thephantom reef ofMaria Theresa Reef is supposed to lie on this parallel in the Pacific Ocean.
Starting at thePrime Meridian and heading eastwards, the parallel 37° south passes through:
The38th parallel south is acircle of latitude that is 38degreessouth of theEarth'sequatorial plane. It crosses theAtlantic Ocean, theIndian Ocean,Australia,New Zealand, thePacific Ocean, andSouth America, including theAndes Mountains andPatagonia.
At this latitude thesun is visible for 14 hours, 48 minutes during theDecember solstice and 9 hours, 32 minutes during theJune solstice.
Starting at thePrime Meridian and heading eastwards, the parallel 38° south passes through:
The39th parallel south is acircle of latitude that is 39degreessouth of theEarth'sequatorial plane. It crosses theAtlantic Ocean, theIndian Ocean,Australasia, thePacific Ocean andSouth America.
Daylight along the 39th parallel south falls under 10 hours a day starting on 17 May and returns to over ten hours a day beginning 29 July. The growth of crops and other plants is considerably slowed during this period of reduced sunlight.
Starting at thePrime Meridian and heading eastwards, the parallel 39° south passes through:
The40th parallel south is acircle of latitude that is 40degreessouth of theEarth'sequatorial plane. It crosses theAtlantic Ocean, theIndian Ocean,Oceania, thePacific Ocean andSouth America. Its long oceanic stretches are the northern domain of theRoaring Forties.
On 21 June 2018, the sun is at 26.17° in the sky and at 73.83° on 21 December, in King Island, Tasmania, which is near the 40th parallel.[2][3]
The maximumaltitude of the Sun is > 35.00º in April and > 28.00º in May.
40th parallel south also marks a line beyond whichAndromeda constellation can no longer be observed.[4]
Starting at thePrime Meridian and heading eastwards, the parallel 40° south passes through:
