As Cassini soared
above high northern latitudes on Saturn's moon Dione, the spacecraft looked down at a region near the day - night boundary.
Not exact matches
This lowered the temperature difference between the Arctic and the middle
latitudes, calming the
high - altitude cyclones that swirl
above the
northern latitudes.
Above, you see the amplification in the
high northern latitudes; in the figures of this paper you see the heat collecting in the southern
latitudes.
Meaning one get an effect similar to the
higher troposphere one gets on Earth with the tropics: «At
latitudes above 60, the tropopause is less than 9 -10 km
above sea level; the lowest is less than 8 km
high,
above Antarctica and
above Siberia and
northern Canada in winter.
Most interesting is that the about monthly variations correlate with the lunar phases (peak on full moon) The Helsinki Background measurements 1935 The first background measurements in history; sampling data in vertical profile every 50 - 100m up to 1,5 km; 364 ppm underthe clouds and

Some of these
northern high latitudes experienced monthly averages 10 - 15 °C (18 - 27 °F)
above normal.
However, this phenomenon can not explain the mismatch to the other published proxy records clearly indicating warm climatic conditions in the
High Northern Latitudes at that time (see discussion
above).
Because of the poor quality of data in general and the obligatory smearing of the nether regions, the much lower average temperature / energy is of the
highest northern latitudes and land areas
above 30N have their own erratic warming trend.
We conclude, therefore, that evolution of GEM concentrations reconstructed
above Greenland can not be generalized to the whole
Northern Hemisphere, but is instead likely to be representative of middle and high northern la
Northern Hemisphere, but is instead likely to be representative of middle and
high northern la
northern latitudes.
