Reinisch and Huang  used scale heights derived from ionograms recorded at Millstone Hill (a middle latitude
site) and Jicamarca (located at the geomagnetic equator) stations for modeling the topside ionospheric profile.
"Muslims do not only live in middle latitude
regions of mostly clear sky as was the case in the early years of Islam but also in high latitude regions where the moon can rarely be sighted, and in areas of high humidity and frequent rain."
335-349) provides a paleoenvironmental record preserved in middle latitude
, high-mountain glaciers.
By 2050, the average annual flow in rivers and the availability of water will go up by between 10 and 40% in high latitude areas and in certain humid tropical areas, and drop by between 10 and 30% in certain dry, middle latitude
and arid tropical areas, some of which are already short of water.
Coastal areas, particularly those on the western side of the middle latitude
areas, tend to have narrower ranges of seasonal temperatures, whereas the interiors of continents in the middle and
Modeled leaf-level transpiration in tropical alpine environments can be substantial and may even exceed transpiration at low elevations in middle latitudes
. At 5000 m elevation, a high diffusion coefficient for water vapor under low air pressure and a high radiation load result in [E.sub.p] rates 50-90% higher in tropical mountains than in middle latitude
Using silica aerogel to reduce the surface temperatures of Mars in local islands of habitability, will be particularly effective in the middle latitudes
, in places where there is water ice trapped near the surface.
The resulting map of the findings shows an overall pattern, in which ice sheets and glaciers lose by far the most mass at the poles, but at the same time, middle latitudes
show multiple areas of growing dryness even as higher latitudes and the tropical belt tend to see increases in water.
These eight scarps, with slopes as steep as 55 degrees, reveal new information about the internal layered structure of previously detected underground ice sheets in Mars' middle latitudes
Mavromichalaki, "Positive and negative ionospheric disturbances at middle latitudes
during geomagnetic storms," Geophysical Research Letters, vol.
NASA explained that in Earth's atmosphere there are waves that send cold air from areas close to the poles toward the middle latitudes
, and that can create or extinguish clouds.
