When the mirror rotating center, solar altitude, and geographic latitude
have deviation, the error value changes from positive to negative, and at a certain moment in the midday, the error is zero.
Thus, the dates of lakes freeze-up are most influenced by mean depth, geographic latitude and elevation above sea level.
(1), lakes freeze up 2.27 days earlier with every degree of geographic latitude (~111 km).
* Age, skin color, geographic latitude
, seasonal variations in sunlight availability, and sunscreen use make it difficult for your body to produce all the vitamin D it needs.
1) Incident solar radiation at a given mountain site and its dependence on geographic latitude
and elevation were calculated from Lowry's (1980) equation, which relates clear-sky direct-beam solar radiation transmissivity [[tau].sub.s] to air pressure p (at elevation z) and solar elevation [varphi] (see Eqs.
And like the French place of lore for wine, Puerto Rico is said to harbor ideal conditions for coffee growing, including the central mountain range's high elevation, ample rainfall, tradewinds, its geographic latitude
, and fertile, volcanic soil.
The measurements were done along the geographic latitude
(the North Pole--Antarctic).
A relevant range of geomagnetic latitudes is shown, 674[degrees]N - 78.7[degrees]S (75[degrees]N - 75[degrees]S in geographic latitudes
MS is generally most prevalent in northern geographic latitudes
. The highest rates of MS prevalence are generally found between the latitudes of 45 degrees north and 65 degrees north .
It is a different story with a large ice sheet that stretches into lower geographic latitudes
: a comparatively brief warm spell of a few thousand years can be enough to cause an ice sheet to melt and herald the end of an ice age.
In addition, geographic latitudes
above 42 [degrees] do not receive enough sunlight during late fall and winter to generate enough vitamin D.
