Six weeks of climate data: Northern Polar Region #12, 30° to 0° West


The twelfth slice of the Arctic Circle gives us the last of Eastern Greenland and a lot of the Greenland Sea.


The coverage pattern is rather strange, since the most measured areas correspond to regions in the middle of the Greenland Sea. There are definitely weather stations at sea, but it is surprising to see so many. This comparison is relative to the coverage of this region, which had only about 1,500 readings over 56 years, less than half of the main Greenland slice's readings, which was already paltry given the land mass.


The Winter data says the temperature has been fairly static, though like Region 11, 1988-1999 showed a cold snap.


The Spring median is also static and the warmest Spring on record is more than thirty years ago.


When the 1975-1988 time interval is an anomaly, it is usually colder than most. It is the warm anomaly in the Summer data in this region. Again, the data reads as static in general.


The Fall looks quite a bit like the Summer.

There were a total of 48 readings, 12 in each season. Intervals can finish 1st, 2nd, 3rd or 4th, and ties are possible.

Most warmest readings: 1975-1988 with 7. Most 2nd warmest readings: 1955-1975 with 8.
Most 3nd warmest readings: It's all over the place, no era got more than 4.
Most coldest readings: 1988-1999 with 7.

Is this region warming from interval to interval? No. The median says static.

Is the rate of warming increasing? No.


So the number of warming slices to non-warming slices of the Arctic Circle is 9 to 3. It is of note that this non-warming region has a lot of readings at sea, though not that close to the North Pole.

Tomorrow, we switch to the Antarctic, looking first at the map.
