There is pretty good evidence in the tropical ocean paleo that the LIA was about a degree cooler in ~ 1700 and since
higher latitudes tend to amplify tropical advection, global temperatures could have be more than 1 C cooler.
Polar Biomes: Areas in
the higher latitudes tend to be dominated by coniferous forests in the warmer portions that transition to tundra in the cooler areas.
Even that which falls on land at
higher latitudes tends to be carried toward the sea on north - flowing rivers, and so into the already somewhat less salty Arctic Ocean.
Not exact matches
And an experiment conducted by the National Institute of Mental Health suggests that contemporary Americans
tend to slip back into a two - phase sleep pattern when (1) they are denied access to artificial lighting and (2) find themselves living under conditions that simulate winter at
high latitudes.
This is because wealthier countries have the scientific resources to detect pests earlier than others, and wealthier countries
tend to be at
higher latitudes.
It also revealed that treeshrews invert Bergmann's rule: individuals from lower
latitudes tended to be larger than those located at
higher latitudes.
When they compared the isotope predictions with the weather - station data, the measured ratios in northern
latitudes tended to be
higher than expected, the team reports tomorrow in Nature.
My question is, how do expect to be able to maintain a much
higher temperature gradient during the LGM than we have today between tropics and
high latitudes, since this would
tend to increase heat flux.
Many folk, especially those who live inland or at
higher latitudes, will
tend to be deficient in three key nutrients.
This also appears to be true on a global scale... the places ranked the best to live year after year
tend to be at
high latitudes.
(57j) For surface + tropospheric warming in general, there is (given a cold enough start) positive surface albedo feedback, that is concentrated at
higher latitudes and in some seasons (though the temperature response to reduced summer sea ice cover
tends to be realized more in winter when there is more heat that must be released before ice forms).
Now if «global» surface temperature anomaly correlated most strongly with the poles or the northern mid to
high latitudes, I might
tend to be more in the CO2 as the dominate forcing camp, but such is not the case.
Land temp rises more because it
tends to be dry, especially in winter in
higher latitudes, and thus lapse rate feedback (which is negative) doesn't play as large a role in reducing CO2 sensitivity.
Ocean - surface temperatures
tend to increase in
high latitudes.
My guess is that, in mid and
high latitudes, windy days indeed
tend to be cloudier than calm days.
Nighttime winds in temperate and tropical
latitudes tend to «decouple» at night, meaning that near - surface winds lose much of their connection with
higher - altitude winds.
In general, the error
tends to be
higher for
higher prediction steps,
higher latitudes, and
higher ionospheric activity levels.
«Previous models
tended to dramatically underestimate the amount of soil carbon at
high latitudes because they lacked the processes of how carbon builds up in soil.
The increased equatorward wind at middle
latitudes tends to push the ionosphere
higher up along magnetic field lines, where the loss rate is lower.
Transitions seasons (autumn and spring) in
tend to be highly volatile throughout the Earth's middle
latitudes as cold, dry polar and warm, moist tropical airmasses interact with
high frequency.
Modeled regional and global climate responses to simulated (107, 110, 111) and reconstructed historical land cover changes over the past century (112) and millennium (113) generally agree that anthropogenic deforestation drives biogeophysical cooling at
higher latitudes and warming in low
latitudes and suggest that biogeochemical impacts
tend to exceed biogeophysical effects (113).
The enhanced polar vortex restricts the annular or seasonal expansion or contraction of the
high latitude stormtracks it
tends to retain the ST in the
higher latitudes in the SH in winter where there is interference in the competing periodicites and systems eg Trebneth 1986 2010.
Koven maintains that previous models
tended to dramatically underestimate the amount of carbon in the soil in
high latitudes.
