Four weeks of climate data:
Northern Temperate Region #3


The third zone is a study in several contrasts. The north is the start of the Asian part of Russia, sparsely populated, as is Kazakhstan, but the region also includes western China and northern India, which means it also includes the Himalayas. The method known as lapse rate lets us compare temperatures from different altitudes, but the differences in population density are very great.


As you can see, the region is fairly well covered, but there are gaps in the north and gaps in the mountainous regions in the south.


The Winter data looks very much like what you would expect in a region whose weather is static, neither significantly warming or cooling. The median in the 21st Century looks to be slightly cooler than the median from 1955-1975.


No strong trend over the entire era, but the big jumps are in the median temperature and the record average low temperature, both steps up happening at the turn of the century.


Because of a record warm Summer in the late 1950s, there is no evidence of warming in the record high measurement and much less than a degree of warming shown in the median and record lows when comparing the first interval (1955-1975) and the last (1999-2010).


The Fall data is much like the Summer, except that the rise in the median and the rise in the low are larger when comparing the first time period and the fourth.

Simply put, this is a region where there is not data that convinces us to 95% confidence level that warming is occurring, which makes the early count in the Northern Temperate Zone 2-1, warming vs. not warming.

Later today, the fourth slice of the Northern Temperate Zone, which contains much of Siberia, Mongolia and the greater part of China.
